Its standout specification is support for sequential read and write throughput of up to 522 MB/s and 565 MB/s. That makes it well suited to moving substantial file sets between computers and the NAS, running a small business file service, maintaining backups, or supporting a modest virtualization and surveillance environment. Two independent network ports can also provide useful flexibility for switched networks, link aggregation, or increased redundancy, depending on the surrounding infrastructure.
The model is sold as a diskless unit, so suitable drives must be selected separately and installed by the owner. This adds an initial configuration step and requires attention to the official compatibility list. It is also more substantial than the two-bay DS223, DS225+, and DS725+ models. Those trade-offs are reasonable because the DS925+ offers additional bays, stronger throughput, and a longer three-year limited hardware warranty.
The DS925+ is the right recommendation for a growing home, a small company, a creative professional, or a power user who wants fast networking and useful redundancy without moving to a much larger enterprise chassis. It is particularly compelling for consolidating family files, backing up several computers, or creating a private media and document repository. Buyers seeking the simplest possible setup should consider a bundled alternative, while users planning intensive shared 4K or 8K production should look toward the DS1825+.
Fast Networking for Growing Workloads
Dual 2.5GbE ports provide substantially more headroom than a single gigabit connection for large backups, media libraries, and shared project files. They also create options for redundancy or aggregation when the rest of the network is prepared to support them.
Protection Built Into the Platform
Synology packages file management, photo management, data protection, virtualization, and surveillance capabilities into the platform. These features make the DS925+ more than a basic enclosure and allow the system to serve several practical roles.

Two-year warranty coverage
The Synology DS223 offers a focused, affordable way to centralize files, automate backups, and create a private collaboration space. Its 4.6 rating is among the strongest in this roundup, and its two-bay diskless format is aimed at home offices, families, and small teams that want ownership of their data without a complex enterprise deployment.
Pros
- Straightforward two-bay layout
- Strong 4.6 customer rating
- Useful collaboration features
- No recurring subscription required
- Compact personal-data focus
Cons
- Drives not included
- Less expansion flexibility

The supplied feature set covers several needs that are often distributed across separate subscription services. Users can consolidate files from computers, phones, and external drives into one accessible location, share project material, and maintain version control. Automated backups can target multiple destinations, including cloud storage and external drives, which is valuable for protecting against device failures, accidental deletion, and ransomware.
The DS223 can also operate as a DIY surveillance system when compatible IP cameras are connected. Motion alerts, recording schedules, and remote viewing make it a versatile addition to a home or small office. The trade-off is that this is a two-bay and diskless product: owners need to provide their own drives, and adding storage eventually means changing the drive configuration rather than adding more bays.
This model is an excellent budget pick for someone moving away from scattered local folders and cloud-only storage. It may not satisfy intensive shared workloads or large media archives, but it addresses the core needs of backup, organization, collaboration, and property monitoring in a manageable two-bay system. Its two-year warranty and ongoing software support provide additional reassurance for owners who want a straightforward first Synology NAS.
A Practical Private File Hub
Centralizing documents, photos, and project files on the DS223 gives family members or collaborators a consistent place to access information. Shared folders and permissions can replace some of the friction associated with moving attachments and maintaining separate copies.
Surveillance Without a Separate Platform
Compatible IP cameras can be organized into a monitoring system with remote viewing, motion alerts, and scheduled recording. This adds security functionality to a device that already serves as a backup and storage hub.

We may earn a commission when you buy through this link, at no additional cost to you.
Its headline capability is support for more than 50 concurrent users working with 4K and 8K projects at speeds of up to 2,239 MB/s. Optional 10GbE or 25GbE upgrade cards allow administrators to match the network path to demanding transfer requirements. Eight hot-swappable bays provide room for dense storage, while expansion units can extend the system from 160TB to as much as 360TB.
Reliability features are another reason to consider this model. High-availability clustering, automated failover, and comprehensive backup options can help maintain access and protect important production data. Enterprise support and dedicated technical account management are also available for business-critical environments. As a diskless product, it requires compatible drives and careful planning, and maximum performance depends on appropriate storage, memory, networking, and configuration.
The DS1825+ is recommended for post-production facilities, broadcast teams, and growing enterprises that already have substantial network and storage requirements. It is less compelling for ordinary household backups because its size, setup demands, and upgrade potential go far beyond those needs. For organizations that can make use of eight bays, high-speed networking, and resilience features, however, it offers the most ambitious capacity and performance in this guide.
Built for High-Bandwidth Production
Optional 10GbE and 25GbE network upgrades give creative teams the bandwidth required for active editing, large media transfers, and simultaneous access by many users. The platform can also host databases, virtual machines, and media services alongside shared project storage.
Resilience for Business-Critical Data
High-availability clustering, automated failover, and comprehensive backup options address the continuity needs of demanding organizations. These features are most valuable when access to shared data and production assets cannot be interrupted casually.

We may earn a commission when you buy through this link, at no additional cost to you.
Hardware includes an AMD Ryzen V1500B quad-core processor, 4GB of DDR4 ECC memory expandable to 32GB, and two M.2 NVMe slots. The NVMe options can be used for cache or storage pools, while four hot-swappable 2.5-inch and 3.5-inch drive bays hold the included hard drives. Dual 2.5GbE LAN ports and two USB 3.2 Gen1 ports provide flexible connectivity.
The included drive set creates a convenient initial capacity, but it also makes this bundle less flexible than buying the diskless DS925+ and selecting capacities independently. Users who may outgrow equal-sized drives or want a different mix of storage should compare that option carefully. The product also supports expansion to nine drives with a DX525 unit, so the platform itself has a clear growth path.
This is a strong choice for a home laboratory, small business, or creative professional who prefers a single package containing the NAS and four hard drives. It is also listed as compatible with third-party hard drives since DSM 7.3, which gives buyers more freedom when replacing or extending the set later. For the least assembly and a balanced 32TB starting point, this bundle is more convenient than the bare DS925+.
Storage and Computing in One Package
Four 8TB Ironwolf drives provide the initial storage while the Ryzen processor and ECC memory provide the processing foundation. The combination is suited to storage consolidation and business-oriented applications without requiring a separate parts search.
Useful Acceleration Options
Two M.2 NVMe slots allow compatible flash storage to be used for cache or storage pools. This can help separate frequently accessed data or active workloads from the hard drive array, depending on the chosen configuration.

Its backup emphasis is a major strength for individuals and families that want automatic copies of important phone and computer data. The system can also act as a private file cloud, making large projects accessible from anywhere and easy to share with family or clients. This approach places control with the owner rather than requiring reliance on a recurring cloud subscription.
The DS124 also supports smart-home security functions, including AI-powered detection of people and vehicles with instant alerts. That makes it more versatile than a basic external drive, particularly for owners who want storage and basic camera monitoring in one device. Its limitations are equally clear: the single bay cannot provide RAID redundancy, and the enclosure offers little room for future drive expansion.
Choose the DS124 when the priority is an approachable personal backup and file hub rather than business continuity or high-volume storage. It is best suited to a secondary copy of important data, not the only copy, and users should retain an appropriate additional backup strategy. For a first NAS in a small home, it provides a manageable introduction to centralized storage, remote access, and basic surveillance.
Automatic Protection for Everyday Devices
Scheduled backups from major mobile and desktop platforms can reduce the risk of losing irreplaceable photos, videos, and documents. Automating the process makes regular protection easier than remembering to copy files manually.
Compact Security Hub
AI-assisted detection can identify people and vehicles and send immediate alerts through the surveillance feature set. It offers a practical way to monitor a home environment while retaining the NAS as the central storage device.

The enclosure uses an Intel Celeron J4125 quad-core processor and includes 2GB of non-ECC DDR4 SODIMM memory, expandable to 6GB with a compatible 4GB module. Networking includes one 2.5GbE and one 1GbE RJ-45 port, offering flexibility for connecting to faster networks while retaining a standard Gigabit option. Synology Hybrid RAID helps users manage the two-bay array with greater flexibility than rigidly matching capacities.
Data protection is a major strength. Btrfs and snapshot technology provide tools for creating recovery points and limiting the effect of accidental changes or malicious activity. The product is also listed as compatible with third-party drives since DSM 7.3, making it less restrictive over time. Its main limitation is the two-bay design, which cannot offer the same later expansion path as four-bay models.
This bundle is a strong fit for a home or small office that wants a two-drive private cloud, automated backups, and snapshot-based recovery in a straightforward package. It is also more convenient than a diskless system for buyers who want a complete initial configuration. Users with rapidly growing archives should start with the DS725+ or another expandable platform instead.
Flexible Two-Drive Storage
Synology Hybrid RAID gives owners a practical way to manage drives of different sizes. That flexibility is useful when one drive eventually needs to be replaced with a larger model.
Recovery-Oriented File System
Btrfs and snapshot functionality help users recover older versions of files and protect against unwanted changes. These features add value beyond simple shared storage, particularly for documents and active project data.

The device can operate as a private cloud for accessing and sharing files and media from different locations. File-server features include team folders and permission control, providing a local alternative to maintaining a separate share point for collaborative work. For media, the photo vault features keep photographs organized and available within the same private environment.
Protection options include backups to multiple destinations, snapshots, versioned files, and immutable snapshots. Those features make it easier to establish an approach that is resistant to malware and accidental changes. The surveillance feature set supports up to 30 IP cameras with monitoring, archiving, and analysis tools, although camera licenses must be purchased separately. The primary compromise is that a camera-focused buyer should account for those extra requirements before installation.
The DS423 is well suited to households or small teams that want more bay flexibility than a two-bay unit but do not need the network throughput of the DS925+. It also works for organizations that want stronger recovery features than the DS223 while remaining within a two-year warranty framework. For shoppers prioritizing protection and collaboration over maximum speed, it offers a particularly balanced feature set.
Ransomware-Resistant Protection Layers
Immutable snapshots, versioned files, and multi-destination backups create several ways to recover when unwanted software changes data. A layered approach is more dependable than relying on one scheduled copy alone.
Sharing for Families and Teams
Team folders, permissions, and secure remote access let collaborators work with shared files without relying on a separate hosted file-sharing service. The same functions can organize family media and everyday household documents.

Cons
- Disks not included
- Lower user rating than leaders
We may earn a commission when you buy through this link, at no additional cost to you.
Capacity growth is a central advantage. A home or small office can begin with two drives, add a DX525 expansion unit for five additional bays, and build a much larger storage pool as its media library or business data grows. This approach makes the DS725+ a potential middle ground between a compact personal NAS and a large eight-bay system that is unused from the beginning.
Protection is built around several layers, including RAID redundancy, automated backups, and snapshot technology. The surveillance feature set supports home or business cameras with advanced analytics, unlimited retention periods, motion detection, and secure remote access. The stated support for up to 30 IP cameras makes it useful for distributed properties or a larger small-business installation.
The DS725+ is ideal for a buyer who anticipates growth but wants to avoid a large initial enclosure. Its diskless format means drives are selected separately, and its 4.1 rating may warrant checking current owner feedback before committing. Even so, the expansion path, multi-site camera support, and three-year warranty separate it from simpler two-bay models. It is a sensible platform for organizations that want to start modestly without closing off future capacity.
Room to Grow the Storage Pool
Adding a DX525 expansion unit increases the enclosure from two bays to seven, enabling a maximum stated capacity of 140TB. This lets a small installation expand according to actual storage demand rather than requiring a large system immediately.
Surveillance Across Multiple Sites
The platform can organize security cameras across a home or small business with motion detection, analytics, remote access, and unlimited retention periods. This makes the DS725+ relevant to owners monitoring more than one property.

Synology DS925+ 48TB Bundle
Four included 12TB drives
Ryzen V1500B quad-core
Four-gigabyte ECC memory
Expansion to nine drives
The 48TB DS925+ bundle is the high-capacity version of the four-bay platform, arriving with four 12TB Seagate Ironwolf hard drives. It combines a 4.5 rating with a substantial initial media library, making it a logical choice for users who already know they need considerable storage and would rather install a ready-made set.
Pros
- Large 48TB starting capacity
- Four matching drives included
- ECC memory and strong processor
- Dual fast network ports
- Clear DX525 expansion path
Cons
- Large bundle footprint
- Mixed capacities harder later
We may earn a commission when you buy through this link, at no additional cost to you.
The Ryzen V1500B quad-core processor and 4GB of expandable ECC DDR4 memory provide a capable foundation for storage, backup, virtualization, and surveillance. Dual 2.5GbE ports support faster network transfers, while two M.2 NVMe slots offer options for cache or additional storage pools. Four hot-swappable drive bays and a DX525 expansion path provide a maximum of nine drives.
Compared with the 32TB bundle, this version starts with 16TB more raw listed capacity because each included drive is larger. That difference is valuable for large photo collections, video archives, or business datasets, but it also means a larger initial financial commitment. The four equal drives may be less flexible than a mixed-capacity arrangement if one drive must eventually be replaced with a different size.
This package is best for a media-heavy household, creative studio, or small business that can use the included capacity immediately. It inherits the platform's three-year hardware coverage and third-party drive compatibility listed since DSM 7.3. Buyers with smaller needs should choose the 32TB bundle or a diskless DS925+, while those requiring even more room can evaluate the eight-bay DS1825+.
Ready-Made Media Storage
Four 12TB Ironwolf drives provide a large starting point for photographers, editors, and teams accumulating large media files. Having the drives included simplifies the initial assembly and capacity planning.
Expandable High-Speed Architecture
Dual 2.5GbE networking, NVMe slots, ECC memory, and support for a DX525 unit create a foundation that can expand as workloads change. It combines high initial capacity with several avenues for future growth.

The DS225+ 16TB bundle provides a middle ground between the compact eight-bay option and a more premium two-bay system. It includes two 8TB Seagate Ironwolf drives with the two-bay Synology enclosure, earning a 4.6 rating and offering a higher starting capacity than the DS225+ 8TB bundle without requiring a four-bay chassis.
Pros
- Includes two 8TB drives
- High 4.6 customer rating
- Snapshot-based data protection
- Flexible SHR management
- 2.5GbE and 1GbE options
Cons
- Only two primary bays
- Memory begins at 2GB
We may earn a commission when you buy through this link, at no additional cost to you.
The Intel Celeron J4125 quad-core processor supplies the computing foundation, while 2GB of non-ECC DDR4 memory can be expanded to 6GB by adding a compatible 4GB module. One 2.5GbE and one 1GbE RJ-45 port provide a useful mix of fast and standard connectivity. The included drives allow a Synology Hybrid RAID setup, and the platform supports Btrfs and snapshot technology for recovery-oriented data protection.
Third-party hard drive compatibility since DSM 7.3 gives owners greater freedom when replacing or supplementing storage. The two-drive design is simple and suitable for homes and small offices that want mirrored protection without managing a large number of bays. The main limitation is that expansion beyond the two bays is not part of the supplied specification, so buyers expecting rapid growth should consider a four-bay or expandable system instead.
This bundle works well for a family photo archive, a small business file server, or a compact private cloud with adequate starting capacity. It is more convenient than a diskless purchase because the storage is included, and its high rating reflects a favorable balance of simplicity and capability. For users who need more memory, more bays, or additional network performance, the DS925+ family offers a clear next step.
Higher Starting Capacity in Two Bays
Two 8TB drives provide 16TB of listed combined capacity while preserving the simplicity of a two-bay arrangement. This configuration is easier to house and manage than a larger multi-bay system.
Protection and Recovery Tools
Btrfs and snapshot technology support creation of recovery points, while Synology Hybrid RAID provides flexible management of the two-drive pool. These capabilities strengthen the system as a central repository for important files.

Buying Guide – How to Choose the Best Synology NAS
The best Synology NAS is not determined by bay count alone. Start with the data you need to protect, the number of users and devices involved, the required network speed, the importance of redundancy, and whether the same system will also support cameras, virtualization, or media production.
Storage Capacity and Expansion
Begin by estimating how much raw capacity you need today and how quickly that amount will grow. Photo collections, home videos, backups, and business datasets can expand much faster than expected, while the usable capacity of a protected array will always be lower than the sum of its drive capacities. A four-bay model offers a useful balance between present flexibility and future room, while a two-bay system is generally easier to accommodate physically but places greater pressure on its initial capacity decision.
Pay close attention to whether the enclosure supports an expansion unit. The DS725+ can add a DX525 and grow to seven bays and a stated 140TB, while the DS925+ supports expansion to nine drives. The DS1825+ begins with eight bays and can scale to 360TB. If your storage needs are uncertain, an expansion-capable model is usually safer than filling every available bay immediately.
Diskless Model or Ready Bundle
A diskless NAS gives you control over drive type, capacity, brand, and budget, but it requires sourcing compatible storage and assembling the system yourself. It is a better option when you want a specific configuration or may replace drives with different capacities later. A bundle arrives with hard drives included, making it more convenient and often simpler to calculate the complete setup.
The DS925+ 32TB and 48TB bundles include four matching Seagate Ironwolf drives, while the DS225+ 8TB and 16TB bundles include two matching drives. Bundles are attractive for first-time owners who want a ready-to-configure system. Diskless models offer greater purchasing flexibility and can be preferable when long-term drive mix is already planned.
Network Speed and Workload
The network connection can be the real limit on a NAS even when the processor and drives are capable. A single-gigabit connection is adequate for basic backups and light file sharing, but larger transfers benefit from 2.5GbE. The DS925+ family and DS225+ bundles include 2.5GbE connectivity, and the DS1825+ can add 10GbE or 25GbE upgrade cards for demanding creative teams.
Consider whether the rest of the network can support the port. A fast NAS connected through slow switches, old client adapters, or congested Wi-Fi will not deliver its full potential. For the DS1825+, the published performance of up to 2,239 MB/s makes the storage and network configuration particularly important. For routine family use, the difference is less visible than for large media files and many simultaneous users.
Protection, Snapshots, and Backups
RAID helps a system continue operating after a drive failure, but it is not a replacement for backups. Important files should be copied to at least one additional location, and snapshots can provide rapid recovery from accidental edits or malware. The DS225+ bundles include Btrfs and snapshot technology, while the DS423 highlights immutable snapshots, versioned files, and multi-destination backup strategies.
Think about recovery scenarios rather than the number of protection features. Decide how many data copies you need, where the extra copy will live, how quickly you need to restore files, and whether the NAS itself must remain available during a failure. Enterprise-oriented models add clustering and automated failover, while the DS725+ combines RAID redundancy with automated backup and snapshot support.
Surveillance and Camera Support
A Synology NAS can serve as a private storage and backup hub while also operating as a video surveillance system. The DS124 is positioned around compact home monitoring with AI-powered detection and alerts. The DS423 and DS725+ support up to 30 IP cameras, with features covering recording schedules, motion detection, remote viewing, analytics, archives, and retention management.
Camera licenses may need to be purchased separately, so the number of cameras supported by the storage and feature set is not the same as the number included without additional licensing. Consider camera count, retention requirements, viewing access, and whether the locations involved are connected over a reliable network. A surveillance deployment also needs sufficient storage for continuous recording and a deliberate plan for protecting the recorded footage.
Memory and Application Workloads
Memory matters most when a NAS runs heavier applications such as virtual machines, databases, and concurrent media services. The DS925+ family uses 4GB of ECC DDR4 memory and can expand to 32GB. The DS225+ begins with 2GB of non-ECC DDR4 SODIMM memory and can reach 6GB. The DS1825+ is aimed at demanding environments, including databases, virtual machines, and media services running alongside shared production storage.
For basic file sharing, photo management, and routine backups, the included memory may be sufficient. Virtualization and multi-user production deserve a closer look at recommended memory and application requirements. ECC memory can suit business environments where memory reliability is important, while non-ECC SODIMM is simpler and more economical in compact home-oriented models.
Form Factor and Noise
The single-bay DS124 is the most compact option, the DS223, DS225+, and DS725+ occupy the two-bay tier, and the DS423 and DS925+ offer four bays. The DS1825+ and its eight-bay enclosure are best suited to dedicated equipment rooms or business installations. A larger chassis can also require more power, cooling, and physical desk space.
Consider where the system will live and whether it will run continuously. Office and living-space placement may make fan noise more noticeable, while a dedicated cabinet or equipment area can better accommodate a larger multi-bay system. Do not compromise on cooling or place drives in a confined area without adequate airflow. The most important factor is choosing an enclosure that fits the available space and the intended expansion plan.
Drive Compatibility and Ownership
Drive compatibility should be checked before buying, particularly for diskless units. The DS925+ supports drives listed on the official compatibility list, while the DS225+, DS925+ bundles, and their listings note third-party compatibility since DSM 7.3. Compatibility helps preserve a wider choice of replacement and expansion drives over the life of the system.
Synology's platform centers on local ownership, private file access, and the ability to use the NAS without depending on a recurring cloud subscription for basic storage functions. That approach can suit households and businesses that want to control where their files are stored. It also means the owner remains responsible for drive health, backups, security, and keeping the software environment current.
How to Use and Care for Your Synology NAS
Begin by placing the NAS in a cool, ventilated, stable location and installing only compatible, fully tested drives. Connect the system to the network, use the Synology setup process to create an administrator account, and configure a strong password and appropriate administrator account name. If the unit includes preinstalled drives, verify that every drive appears in the storage manager before creating any shared folders or schedules.
After the initial setup, organize data into shared folders rather than placing important files in a single catch-all location. Assign permissions according to who needs access, enable the relevant backup applications for computers and phones, and create a second backup destination. For a camera system, install required licenses, define recording schedules, confirm motion alerts, and test remote viewing before relying on the system for security.
Ongoing care matters. Monitor drive health, review backup logs, confirm that snapshots or versioned files are being created, and keep enough free capacity for maintenance. Test restoring important files occasionally, maintain a separate copy of critical data, and apply software updates through the normal management interface. If performance declines, check network conditions and storage configuration before adding hardware, and back up the data before replacing drives or expanding the system.
Frequently Asked Questions
Which Synology NAS is best for a home user?
The best home model depends on how much the NAS will do. The DS124 is the simplest choice for personal backups and a basic camera hub, while the DS223 adds a two-bay protected configuration and broader collaboration features. Home users with large media libraries or faster networking needs may prefer a four-bay DS925+ or an expandable DS725+.
Do diskless Synology NAS models include hard drives?
No, a diskless model is sold without the drives that the owner will install. The DS925+, DS223, DS1825+, DS124, DS423, and DS725+ listings identified in this guide are diskless. The separate DS925+ and DS225+ bundle listings include Seagate Ironwolf hard drives as part of the package.
Is RAID a substitute for backing up important files?
No. RAID is intended to help an array continue functioning when a drive fails, but it does not protect against accidental deletion, malware, device failure, theft, or a problem affecting the entire NAS. Important data should also be copied to another location and protected with snapshots or versioned recovery where appropriate.
Do I need 2.5GbE for a home NAS?
It is helpful when you routinely transfer large media files, maintain several devices, or share substantial project folders. A gigabit connection can still work well for routine documents and smaller backups, but the faster connection offers more headroom. The benefit also depends on compatible client devices, switches, and network cabling.
Can I use third-party hard drives with these Synology NAS models?
The supplied information for the DS225+, DS925+, and the listed DS925+ bundles states that they are compatible with third-party hard drives since DSM 7.3. The diskless DS925+ listing specifically says it supports drives on the official compatibility list. Check the current model-specific requirements and select carefully before purchasing or replacing a drive.
How many IP cameras can Synology NAS systems support?
The DS423 and DS725+ are described as supporting up to 30 IP cameras, and the DS124 is focused on compact home security. Additional camera licenses may be required, and the listed camera limit is not a statement that every license is included. Account for licensing, storage retention, network quality, and monitoring requirements.
Should I buy a diskless NAS or a hard drive bundle?
A diskless model offers more control over drive brands, capacities, and replacement strategy, making it suitable for buyers who already have a storage plan. A bundle is more convenient and gives a clearer starting configuration. The included DS925+ and DS225+ bundles are particularly helpful for first-time owners who want a complete system with less assembly.
What does a two-year or three-year warranty mean for a Synology NAS?
The warranty periods shown in the product information apply to the listed Synology hardware and are accompanied by customer support and ongoing software updates. A bundle may also include separately sold Seagate hard drives, whose own warranty terms should be checked. Keep purchase documentation and confirm the current coverage terms before making a claim.
Final Thoughts on Choosing the Best Synology NAS
The DS925+ is the strongest overall recommendation for buyers who want a balanced combination of four bays, fast networking, broad applications, and room for expansion. The DS223 stands out as the best budget-oriented choice for straightforward family or small-office backup and collaboration, while the DS1825+ is the premium option for demanding multi-user production environments.
Prioritize your actual workload before choosing a model. One-bay buyers should focus on simple personal backups, two-bay users should consider RAID and future capacity, and four-bay or eight-bay systems make more sense when media growth, camera recording, virtualization, or shared production files are central. Also compare diskless systems with ready bundles, and check drive compatibility, memory, network speed, expansion requirements, and license needs.
Finally, check current prices and listing contents before ordering because costs, bundles, availability, and technical details can change. The supplied product information is the factual basis for this guide, but the current Amazon listing should confirm the exact model, included drives, specifications, warranty, and any optional requirements that may apply to your configuration.
