Read on for the detailed analysis.

Synology DS925+ Business Storage Capabilities

Synology's 4-bay flagship delivers the most polished NAS software on the market, with trade-offs in processor generation and expansion options.

Price: ~$640 | Bays: 4 (expandable to 9) | Networking: Dual 2.5GbE

DiskStation Manager remains the most mature NAS operating system available, with an extensive app ecosystem, thorough documentation, and the broadest third-party integration support of any platform in this comparison.

Hardware Specifications:

The DS925+ runs on AMD's Ryzen Embedded V1500B—a quad-core processor released in 2018. For straightforward file sharing and backup, it performs adequately. Compared to the Intel Pentium Gold 8505 in UGREEN's lineup, the V1500B is a generation behind:

  • No hardware video transcoding (Plex users will hit CPU limits quickly)
  • Slower performance for Docker containers and virtual machines
  • Higher idle power draw (18–28W) relative to performance output

Synology also removed the PCIe expansion slot from the DS925+. Unlike the older DS923+, you cannot add a 10GbE card later. If you need 10GbE, the dual 2.5GbE ports with link aggregation are your only option—or you need to step up to the DS1525+.

Where Synology Excels:

  • DSM software: The backup solutions, photo management, and surveillance apps are best-in-class
  • Synology Hybrid RAID (SHR): Unlike standard RAID, SHR lets you mix drive sizes and expand storage without wiping drives—ideal for businesses that add capacity gradually
  • QuickConnect + Tailscale: Easy remote access without complex VPN setup
  • Long-term support: Software updates for 6+ years; established VAR channels for enterprise support

Drive Compatibility (DSM 7.3+)

Synology reversed their 2025 drive restrictions. Third-party drives now work with only a warning message. Use any compatible drive.

Growth Path: Expansion Support

The DS925+ is the only 4-bay NAS in this comparison that supports expansion units. The DX525 adds 5 more bays, scaling to 9 drives total. UGREEN and UniFi currently require a new chassis for more capacity.

The Verdict

Best for businesses prioritizing software stability over hardware specs. The aging CPU limits transcoding and VM performance.

UGREEN DXP4800 Plus Hardware and Value Proposition

The DXP4800 Plus offers more processing power and connectivity per dollar than any other 4-bay NAS in this comparison, including built-in 10GbE networking.

Price: ~$560-700 | Bays: 4 | Networking: 1× 10GbE + 1× 2.5GbE

For roughly the same price as the DS925+, UGREEN ships a newer Intel processor, DDR5 memory, and 10GbE connectivity without add-on cards.

What Sets It Apart:

  • Intel Pentium Gold 8505: 5-core hybrid architecture delivers measurably higher throughput than the Synology's V1500B in transcoding, Docker, and VM benchmarks
  • Built-in 10GbE: No add-on cards needed; the second 2.5GbE port enables network segmentation
  • 8GB DDR5 RAM: Expandable to 64GB for memory-intensive workloads
  • Performance per watt: The Intel chip delivers substantially more compute per watt for transcoding and Docker workloads, though absolute idle draw (25–30W) is slightly higher than the DS925+'s 18–28W
  • No drive restrictions: Use any compatible SATA or NVMe drive

Why M.2 Slots Matter:

The two NVMe slots enable SSD caching, which noticeably improves multi-user access to frequently-used files. If your team runs QuickBooks, databases, or collaborative documents, SSD cache eliminates the lag of spinning drives.

Where UGREEN Falls Short:

UGOS PRO is functional but noticeably less polished than DSM. The app ecosystem is smaller, documentation is thinner, and some enterprise features (like advanced snapshot management) are still in development.

Support & Compliance Considerations:

UGREEN lacks established enterprise support channels—most purchases go through Amazon or Newegg with standard consumer warranty. For businesses with strict compliance requirements (HIPAA, localized data sovereignty), UGREEN's newer entry into the market may require deeper security vetting compared to Synology's proven track record. Using non-listed RAM or drives may also void support.

The Verdict

Best hardware-per-dollar in this comparison. Weaker enterprise support and compliance track record are the trade-offs.

UniFi UNAS Pro 8 Rackmount Storage for UniFi Environments

The UNAS Pro 8 delivers eight hot-swap bays and triple 10GbE connectivity at a price point typically reserved for 4-bay NAS systems.

Price: $799 (MSRP via Ubiquiti Store) | Bays: 8 | Networking: 2× 10G SFP+ + 10G RJ45

Third-party retailers like CDW and B&H may charge $830–$960 due to demand markups. Purchase directly from the Ubiquiti Store to secure the $799 MSRP. For IT-managed offices already running UniFi switches, access points, and Protect cameras, the UNAS Pro 8 consolidates storage management into a single platform.

The Hardware:

  • Eight 3.5" bays plus two internal M.2 NVMe slots
  • 16GB RAM
  • Three 10GbE ports (two SFP+, one RJ45)
  • 2× 550W hot-swap redundant PSUs
  • 2U rackmount form factor

UniFi Ecosystem Integration:

UniFi OS consolidates storage, network, and camera management into a single interface. Adding UNAS means one fewer management platform to maintain.

Noise Warning: This Is Not a Desktop NAS

The UNAS Pro 8 is enterprise rackmount hardware. The cooling fans are designed for server rooms and IT closets, not open office environments. For quiet desktop use, the UNAS 4 ($379) launched in early 2026 and is currently sold out—sign up for back-in-stock notifications on the UniFi store.

Software Maturity in 2026:

UniFi's NAS software has progressed since launch but remains notably behind DSM and UGOS PRO in depth. As of mid-2026 it handles: file sharing (SMB/NFS), user management, snapshot scheduling, and UniFi OS app integration (Protect cameras, network dashboards). What's still missing: granular ACLs, advanced backup scheduling, and a mature app ecosystem. If your business relies on active directory integration or detailed audit logging, verify feature availability before purchasing.

The Full Desktop Option — UNAS 4:

The UNAS 4 ($379, 4-bay, 2.5GbE, M.2 NVMe slots, desktop form factor) launched in early 2026 and immediately sold out. It fills the gap for smaller UniFi offices that need a quiet, rackmount-free option. Check the UniFi store for restock availability.

Ecosystem Risk

UniFi's tight integration is a double-edged sword. If your UniFi OS Controller goes down or an update breaks compatibility, you may lose management access to both network and storage. Third-party drives are supported, but verify compatibility before purchasing.

The Verdict

Strong bay-per-dollar value for UniFi shops with proper rack space. Not suitable for quiet office environments.

For setup guidance, see our complete UniFi NAS business guide. If you're comparing the UNAS 4, Pro 4, and Pro 8 head-to-head, see our detailed UNAS model comparison.

Key NAS Market Developments in 2026

Three trends are shaping the small business NAS market this year.

10GbE Is No Longer Optional for Growing Businesses

WiFi 7 access points, modern workstations, and video workflows can saturate gigabit connections. UGREEN includes 10GbE in the DXP4800 Plus base price. The DS925+ does not offer a 10GbE upgrade path—without a PCIe slot, teams working with large media files may find the 2.5GbE ceiling limiting. For a deeper look at when 10GbE is worth the investment, see our 10 Gigabit Ethernet guide.

Drive Policies Have Normalized

Synology's initial push toward branded-only drives created friction, but DSM 7.3 effectively reversed the policy. All three vendors now support third-party drives without feature limitations.

QNAP's 2026 Lineup Is Worth Watching

QNAP shipped several new models in 2026, most notably the TVS-h877AX, TVS-h1277AX, and TVS-h1677AX—all running AMD Ryzen 5 PRO 7645 processors (Zen 4 architecture, 6-core/12-thread, up to 5.1 GHz) with the QuTS hero OS and ZFS file system. ZFS brings self-healing storage, inline deduplication, and compression that Synology's ext4/Btrfs can't fully match. For businesses with large datasets, frequent snapshots, or VM workloads, that's meaningful.

QNAP also released QuTS hero h6.0 with dual-NAS high availability—active/active failover between two NAS units—which is enterprise-grade functionality at a price point that's now within reach for larger small businesses.

The caveat: these are enterprise-class systems priced accordingly (the TVS-h877AX starts above $3,000 diskless). QNAP's setup is also more complex than Synology DSM. The dual-OS architecture (QTS vs. QuTS hero), extensive networking options, and less polished UI make it better suited to environments with dedicated IT management. We'll cover QNAP directly in a future comparison.

The TrueNAS Alternative

For teams comfortable with Linux and ZFS, the TrueNAS Mini X+ (~$2,700 diskless) from iXsystems offers a turnkey ZFS appliance with 5+2 hot-swap bays, an octa-core Intel C3758, 32GB ECC DDR4, and dual 10GbE—backed by enterprise support. TrueNAS SCALE (free, open-source) can also run on any x86-64 hardware, giving budget-conscious IT teams ZFS-grade data integrity, native Docker support, and zero licensing costs. The trade-off is a steeper learning curve and the absence of polished mobile apps. If your priority is data integrity over software convenience, TrueNAS belongs on the shortlist.


AI NAS Features for Small Business

Most AI NAS marketing refers to photo organization and ransomware detection, not on-device LLM inference. Here's what each feature tier delivers in practice.

What AI NAS delivers right now:

  • Smart photo/video organization: Facial recognition and object tagging for media libraries. Available on Synology Photos, QNAP QuMagie, and UGREEN's photos app. Works on standard hardware—no NPU required.
  • Ransomware detection: Synology Active Insight and QNAP Security Center monitor for unusual write patterns and trigger alerts. This is the most practically useful AI feature for small offices without a dedicated security team.
  • Document de-identification: Synology's AI Console (available on DS1525+ and above) can strip PII from documents using on-device processing—relevant for healthcare, legal, and financial offices.

What AI NAS marketing sometimes implies but most SMBs don't actually need:

Running a local LLM (private ChatGPT equivalent) directly on the NAS. This requires a dedicated NPU or GPU, substantial RAM, and hardware like the QNAP QAI-h1290FX—an enterprise AI storage server well above small business budgets.

Future-Proofing Guidance

If AI features matter for your roadmap, the DS1525+ (PCIe expansion slot for future cards) and UGREEN DXP6800 Pro (Intel Core i5, 64GB RAM ceiling) offer more headroom than the DS925+. For most teams, the AI NAS pitch is ahead of practical SMB needs in 2026—buy for your current workflow, not the one vendors are projecting.

Storage Sizing and Capacity Planning

Calculating usable NAS capacity requires accounting for RAID overhead, and most first-time buyers underestimate total cost.

Use this formula:

Usable Capacity = (Number of Drives - 1) × Drive Size (RAID 5)

Current DataRecommended ConfigUsable Space
2-5 TB4× 4TB12 TB
5-15 TB4× 8TB24 TB
15-40 TB6× 12TB (RAID 6)48 TB

Plan for 2× your current data to accommodate growth.

Not Sure What You Need?

Capacity planning is where most businesses get tripped up—RAID overhead, future growth, and drive selection add up quickly. If you're unsure whether you need 20TB or 50TB, or which platform fits your workflow, we can help.

Total Cost of Ownership: What You'll Actually Spend

NAS vendors list prices for diskless enclosures. The actual upfront cost is significantly higher once you add drives. Here's what a fully populated setup looks like:

ComponentDS925+ BuildDXP4800 Plus BuildUNAS Pro 8 Build
NAS unit (diskless)~$640~$600$799
4× 8TB NAS drives (WD Red Plus)~$680~$680~$680 (partial fill)
8× 8TB NAS drives~$1,360
NVMe cache (optional, 2× 1TB)~$120~$120~$120
10GbE switch (if needed)N/A~$300–800~$300–800
Typical total (4 drives)~$1,320~$1,400~$1,600
Typical total (8 drives)~$2,280

Budget for the full build, not just the enclosure. A $640 NAS with four 8TB drives is a $1,300+ investment.

SMR vs. CMR: Choosing the Right NAS Drives

When purchasing NAS drives, verify that every drive uses CMR (Conventional Magnetic Recording) technology. SMR (Shingled Magnetic Recording) drives are cheaper per terabyte but can cause RAID rebuilds to stall or fail entirely—the sustained write load overwhelms SMR's internal cache, and the RAID controller may flag healthy drives as failed.

Safe choices: WD Red Plus, WD Red Pro, Seagate IronWolf, Seagate IronWolf Pro, Toshiba N300.

Avoid: Plain WD Red (all capacities use SMR), standard Seagate Barracuda, and any drive whose spec sheet does not explicitly state "CMR" or "PMR."

Manufacturers have historically changed recording technology within the same product line without updating model numbers. Always verify the specific model number against current spec sheets before purchasing.

Power Consumption Comparison

For NAS units running 24/7, power draw affects operating costs over time. Based on published specifications and independent reviews:

MetricSynology DS925+UGREEN DXP4800 PlusUniFi UNAS Pro 8
Idle (drives active)18–28W25–30W~35W (est.)
Active workload38–42W45–55W~55W (est.)
HDD hibernation~12W~18W (est.)N/A

The DS925+'s older Ryzen V1500B is a lower-power chip, which partially offsets its performance disadvantage. Over three years of 24/7 operation at $0.13/kWh, the difference between 28W and 40W average draw works out to roughly $40–45 per year.

The 3-2-1 Backup Rule

Follow the industry standard: 3 copies of your data, on 2 different media types, with 1 copy offsite. Your NAS handles the first two; script nightly backups to iDrive, Backblaze B2, or AWS Glacier for the offsite copy. Our complete 3-2-1 backup rule guide walks through implementation step by step.

Frequently Asked Questions

Is the Synology DS925+ worth buying in 2026?

For straightforward file storage and backup, the DS925+ remains a solid choice thanks to Synology's mature software. However, the AMD V1500B processor dates to 2018 and struggles with Plex transcoding, heavy Docker workloads, and virtualization. If those matter to you, the UGREEN DXP4800 Plus offers more capable hardware for similar money.

Can I upgrade the DS925+ to 10GbE later?

No. Synology removed the PCIe expansion slot from the DS925+. Your only option is dual 2.5GbE with link aggregation (theoretical 5Gbps). If 10GbE is on your roadmap, consider the DS1525+ or the UGREEN DXP4800 Plus, which includes 10GbE out of the box.

Is UGREEN's software reliable enough for business use?

UGOS PRO handles the essentials: file sharing, user management, Docker, and media streaming. But it's noticeably less polished than Synology's DSM. Documentation is thinner, the app ecosystem is smaller, and you'll occasionally hit rough edges. If you're comfortable troubleshooting or have IT support, it's fine. For hands-off operation, Synology is still the safer choice.

Is the UniFi UNAS Pro 8 too loud for an office?

Yes, unless you have a dedicated server closet or IT room. The UNAS Pro 8 is a 2U rackmount with enterprise-grade cooling fans. It belongs in a rack, not under a desk. The UNAS 4 ($379), a quiet desktop 4-bay option, launched in early 2026 but is currently sold out. Check the UniFi store for restock or consider the UNAS 2 ($199) for a smaller footprint in the meantime.

Which NAS offers the best value in 2026?

The UGREEN DXP4800 Plus delivers the most hardware per dollar: Intel Pentium Gold 8505, 8GB DDR5, and built-in 10GbE for around $600. By comparison, the similarly priced DS925+ ships with a 2018-era CPU and no 10GbE upgrade path.

Should I use a NAS or cloud storage for my business?

Both. A NAS gives you fast local access, one-time cost, and full data privacy. Cloud storage provides offsite redundancy for disaster recovery. The practical approach: use your NAS for active data and script nightly backups to cold cloud storage like iDrive or Backblaze B2. For a full breakdown of cloud options, see our best cloud storage for small business comparison.

Should small businesses consider QNAP in 2026?

QNAP is worth evaluating if your team needs ZFS-based storage, advanced virtualization, or Docker-heavy workloads. New 2026 models like the TVS-h877AX feature AMD Ryzen 5 PRO 7645 processors (Zen 4 architecture, 6-core/12-thread) with strong multi-core performance and QuTS hero's ZFS file system. These are enterprise-class systems priced accordingly—the TVS-h877AX starts above $3,000 diskless. The trade-off: QNAP's dual-OS environment (QTS and QuTS hero) is more complex to configure than Synology DSM. For straightforward file storage and backup at a lower budget, Synology or UGREEN are easier to deploy and operate day-to-day.

What does "AI NAS" actually mean for a small business?

It depends on the vendor. Most AI NAS marketing refers to AI-assisted photo organization and ransomware detection—features present across Synology, QNAP, and UGREEN at current price points. True on-device LLM inference (running a private AI model on the NAS) requires dedicated NPU hardware and substantially more budget. For most 5–20 person businesses in 2026, the practical AI features are smart photo management, automated backup verification, and anomaly-based threat detection—all available on standard models without a premium.
