A NAS for a small business has to hold up under several people pulling files at once, not just a single home user, which puts real weight on network speed, directory integration, and warranty tier that a personal NAS review rarely covers. It's also easy to forget that the NAS itself needs backing up, ransomware targets NAS devices specifically, and a power outage mid-write can corrupt a RAID array without a UPS in the loop.
Below are 8 NAS options for small businesses we evaluated on concurrent-user network throughput, bay count, directory and backup integration, and warranty tier, ranging from a 2-bay entry point to a 4-bay unit built for a growing team's file and media library.
6 Criteria to Look For Before Buying a NAS for Small Business
Key buying criteria so you get the right fit the first time.
A gigabit network becomes the bottleneck before the NAS does
On a standard 1GbE connection, 5 people transferring files simultaneously split that bandwidth, adequate for documents but noticeably slow for large media files. Moving to 2.5GbE or 10GbE networking, on both the NAS and a matching switch, multiplies per-user throughput and is worth the upgrade once a team regularly works with large files together.
Directory integration gets complex past about 5 users
Most small businesses eventually migrate from individual NAS accounts to a centralized directory sync as the team grows. That setup is complex enough that it typically needs IT help to configure correctly the first time, so budget for that either as internal time or an outside consultant rather than assuming it's a quick toggle.
The NAS itself needs to be backed up, not just used as a backup target
Most buying guides treat a NAS purely as a backup destination for computers, but ransomware attacks specifically targeting NAS devices are increasing. Set up cloud backup integration for the NAS's own data, not just the devices backing up to it, so a ransomware event or hardware failure doesn't take out the only copy of your files.
Pair a business NAS with a UPS, it's not optional
A power outage mid-write can corrupt a RAID array, which is a much bigger problem for a business NAS holding shared files than for a personal one. A USB-connected UPS lets the NAS detect the outage and shut down safely, and it should be budgeted as a required companion purchase, not an accessory.
Value-tier and Plus/Pro-tier warranties are not interchangeable
Value-tier NAS models typically carry a shorter warranty with no enterprise support option, while Plus or Pro-tier models offer longer coverage and an enterprise support add-on. For a NAS holding business-critical files, the longer warranty and support option are usually worth the price step up over a Value-tier equivalent.
Match bay count to team growth, not just current headcount
A 2-bay NAS covers a small team today but leaves little room to add storage later without replacing the whole unit, unless it's specifically built as expandable like the Synology DS725+. A 4-bay unit costs more upfront but avoids a second purchase in a year or two if the business is actively growing.
8 Best NAS for Small Businesses in 2026
Synology 4-Bay DiskStation DS925+ (Diskless)
About this pick
The DS925+ is Synology's current 4-bay business-tier NAS, built to handle a small team's shared files, backups, and growing storage needs in one unit. As a Plus-tier model, it's positioned for the enterprise support add-on and longer warranty coverage that Synology's Value-tier models don't offer.
For a team past 5 concurrent users, pair it with a 2.5GbE or faster network switch rather than plain gigabit, since several people transferring large files at once on a 1GbE connection quickly becomes the bottleneck, not the NAS itself.
Best for: Small businesses that want the most headroom for team growth and enterprise support
Check price on AmazonPros
- +4 bays give real room to grow with a small business
- +Plus-tier warranty and enterprise support option
- +Synology DSM includes directory sync tools for centralized accounts
- +Strong RAID redundancy options
Cons
- −Diskless, drives are an additional cost
- −Most expensive pick in this list
- −Needs a faster-than-gigabit switch to avoid becoming a bottleneck with several concurrent users
UGREEN NAS DXP4800 Plus 4-Bay NAS
About this pick
UGREEN's DXP4800 Plus pairs an Intel Pentium Gold 8505 5-core CPU with 4 bays, giving it enough processing headroom to run business apps and backup jobs alongside file sharing without stalling. It undercuts the Synology DS925+ by about $80 while still offering 4 bays of expansion room.
As with any device holding your business's only copy of critical files, plan for the NAS itself to be backed up, cloud backup integration for the NAS is a genuine requirement given rising ransomware activity targeting NAS devices specifically, not an optional extra.
Best for: Businesses that want 4-bay capacity and strong CPU performance without the Synology premium
Check price on AmazonPros
- +Strong 5-core CPU for the price
- +4 bays at a lower price than the Synology equivalent
- +Supports cloud backup of the NAS itself
- +Good balance of performance and cost
Cons
- −Diskless, drives are an additional cost
- −Value-tier warranty and support versus Synology's Plus-tier enterprise add-on
- −Newer platform than Synology's more established DSM ecosystem
UGREEN NAS DXP2800 2-Bay
About this pick
The DXP2800 is a 2-bay NAS aimed at content creators and small teams that don't yet need 4 bays of storage. It's the cheapest 2-bay pick in this list and a reasonable entry point for a business just starting to centralize file storage.
For teams under 5 people on a standard gigabit network, this is usually adequate throughput for document and small-file work. Once the team grows past that, plan for either a network upgrade or a move to a 4-bay unit with faster networking.
Best for: A small team or solo business just starting to centralize file storage on a budget
Check price on AmazonPros
- +Cheapest 2-bay pick in this list
- +Solid entry point for a small, growing team
- +Simple 2-bay RAID 1 setup for basic redundancy
- +Good value for content-creator workflows
Cons
- −Only 2 bays, less expansion room than the 4-bay picks
- −Standard gigabit networking may bottleneck once the team grows past 5 users
- −Value-tier support versus a Plus-tier model
Synology DS725+ Expandable NAS Storage (2-Bay, Diskless)
About this pick
The DS725+ starts at 2 bays but is built as an expandable private cloud platform, letting a business grow storage capacity without replacing the whole unit later. It's positioned for home and small business use, with Synology's Plus-tier support and warranty options.
As the business scales past 5 or so regular users, most small businesses eventually migrate from individual NAS logins to centralized directory sync, and that integration is complex enough that it typically needs IT help to set up correctly the first time.
Best for: A small business that wants to start at 2 bays with a clear path to expand later
Check price on AmazonPros
- +Expandable path avoids a full NAS replacement later
- +Plus-tier Synology warranty and support option
- +Strong DSM software ecosystem
- +Solid choice for a business planning to scale
Cons
- −Pricier than the UGREEN 2-bay for the same starting bay count
- −Directory integration setup usually needs IT assistance
- −Expansion unit is a separate purchase
Synology DS225+ Private Cloud Media Server (2-Bay, Diskless)
About this pick
The DS225+ includes an Intel CPU built for hardware transcoding, useful for a small business that streams or shares video content internally, marketing teams, agencies, or any office regularly reviewing media files together. It also covers general photo backup and file sharing duties.
Since it's a Value-tier model rather than Synology's higher business tier, expect a shorter warranty and no enterprise support add-on, a real tradeoff to weigh if this NAS will hold business-critical data rather than just media files.
Best for: Small teams that regularly stream or review video and photo content internally
Check price on AmazonPros
- +Hardware transcoding useful for media-heavy small teams
- +Solid photo backup and sharing features
- +Competitive price for the transcoding CPU included
- +Good fit for agencies or content-focused offices
Cons
- −Value-tier warranty, no enterprise support option
- −Only 2 bays
- −Less suited to pure business file storage than the Plus-tier models
Synology DS423 Family & Business Backup (4-Bay, Diskless)
About this pick
The DS423 is a Value-tier 4-bay NAS built around secure file sharing, photo vault duties, and video surveillance storage, a solid fit for a small business that wants a security camera backend alongside general file backup. Four bays at this price make it the most affordable 4-bay pick in this list.
Because this NAS is likely to become the single copy of both surveillance footage and business backups, treat it as a device that itself needs backing up, cloud backup integration for the NAS's own data protects against both hardware failure and the rising rate of ransomware attacks targeting NAS devices.
Best for: Small businesses that want a combined surveillance and backup NAS on a budget
Check price on AmazonPros
- +Cheapest 4-bay pick in this list
- +Built-in support for video surveillance storage
- +Solid photo vault and file sharing tools
- +Good entry point into 4-bay Synology hardware
Cons
- −Value-tier warranty and support, not Plus-tier
- −Weaker CPU than the Plus-tier 4-bay picks
- −Best suited to backup and surveillance rather than heavy concurrent file access
QNAP TS-264-8G-US 2-Bay Desktop NAS
About this pick
The TS-264 gives small businesses that prefer QNAP's software ecosystem over Synology's DSM a 2-bay option with 8GB of RAM included, more memory out of the box than most 2-bay competitors in this list. That extra RAM helps when running multiple business apps or virtualization features alongside file sharing.
QNAP's own directory and backup tools cover similar ground to Synology's, centralized directory sync and cloud backup of the NAS itself are both available, but the interface and setup flow differ enough that IT staff already trained on one ecosystem should account for the learning curve switching to the other.
Best for: Small businesses that prefer QNAP's software ecosystem over Synology DSM
Check price on AmazonPros
- +8GB RAM included out of the box
- +Solid alternative for businesses preferring QNAP's software
- +Supports centralized directory integration
- +Good multitasking headroom for a 2-bay unit
Cons
- −Pricier than the UGREEN or Synology DS423 2/4-bay options
- −QNAP's ecosystem has a learning curve for teams used to Synology
- −Only 2 bays despite the higher price than some 4-bay picks
Western Digital 8TB WD Red Plus NAS Internal Hard Drive
About this pick
This is a bare 3.5-inch hard drive, not an enclosure, built specifically for NAS use with CMR recording and a 256MB cache rated for continuous multi-bay operation. Every diskless NAS in this list needs drives like this one purchased separately to actually function.
At 5640 RPM and SATA 6 Gb/s, it's built for the always-on, multi-drive vibration environment inside a business NAS rather than a single external drive, which matters for long-term reliability once several of these are running together in a RAID array.
Best for: Populating any of the diskless NAS units in this list with drives built for 24/7 business use
Check price on AmazonPros
- +Purpose-built for NAS vibration and always-on workloads
- +CMR recording, not the less NAS-friendly SMR type
- +256MB cache supports smoother multi-user access
- +Needed to actually populate any of the diskless NAS units above
Cons
- −This is a drive, not a NAS enclosure, buy alongside a diskless unit above
- −8TB may need to be purchased in pairs or more for full RAID capacity
- −Higher RPM competitors exist at a premium if raw speed matters most
How We Evaluated These NAS for Small Businesses
Each pick was assessed across 5 criteria weighted for real-world use.
Concurrent-user network throughput
Weighed each NAS's network speed against how many people would realistically pull files at once, since a 1GbE connection bottlenecks fast with 5 or more simultaneous users.
Directory and account integration
Checked whether each platform supports centralized directory sync as a business scales past individual per-user accounts, and how complex that setup realistically is.
Backup of the NAS itself
Looked at whether each NAS supports cloud backup of its own data, not just backup of connected computers, given rising ransomware activity targeting NAS devices directly.
Bay count and expansion path
Compared 2-bay versus 4-bay options and whether each platform offers a genuine expansion path without a full unit replacement as storage needs grow.
Warranty and business support tier
Compared Value-tier versus Plus/Pro-tier warranty length and enterprise support availability, since business-critical data justifies a different tier than personal use.
How to Choose the Right NAS for Small Businesses
By Team Size and Network Throughput
Concurrent users, not just total headcount, determine what network speed your NAS actually needs.
| Team size | Recommended network | Best pick |
|---|---|---|
| Under 5 concurrent users | Standard 1GbE is adequate | UGREEN DXP2800 2-Bay |
| 5-15 concurrent users, document-heavy | 2.5GbE recommended | Synology DS725+, QNAP TS-264 |
| 5-15 concurrent users, large media files | 2.5GbE or 10GbE required | Synology DS925+, UGREEN DXP4800 Plus |
| Media/streaming-focused team | Hardware transcoding matters more than raw network | Synology DS225+ |
By Bay Count and Growth Plan
Starting small, may never need to grow
UGREEN DXP2800 2-Bay or Synology DS225+ cover a small team's basics without paying for expansion room you may not use.
Starting small, but expect to scale
The Synology DS725+ starts at 2 bays with a genuine expansion path, avoiding a full replacement later.
Already need real headroom now
The Synology DS925+ or UGREEN DXP4800 Plus give 4 bays from day one for a growing business.
Need surveillance storage alongside backup
The Synology DS423 combines 4-bay backup capacity with built-in video surveillance storage support.
Protecting the NAS Itself
A business NAS is often the single copy of critical files, so protecting the NAS is as important as what it protects.
| Risk | Protection | Applies to |
|---|---|---|
| Ransomware targeting the NAS directly | Cloud backup of the NAS's own data | Every pick in this list |
| Power outage corrupting RAID mid-write | USB-connected UPS with safe shutdown trigger | Every pick in this list |
| Directory sync complexity past 5 users | Budget IT time or a consultant for setup | Synology and QNAP picks with directory sync |
None of the NAS units above include a UPS in the box, treat a UPS as a required companion purchase rather than an optional accessory once the NAS holds business-critical data.
Warranty Tier Quick Reference
| Pick | Tier | Enterprise support |
|---|---|---|
| Synology DS925+ | Plus | Available as add-on |
| Synology DS725+ | Plus | Available as add-on |
| UGREEN DXP4800 Plus | Value/Plus hybrid | Limited |
| Synology DS225+ | Value | Not available |
| Synology DS423 | Value | Not available |
| UGREEN DXP2800 | Value | Not available |
| QNAP TS-264 | Standard | Limited |
Choosing Your Drives
Every diskless NAS in this list needs drives purchased separately, and not every hard drive is built for NAS duty.
Buying drives for any diskless NAS above
The WD Red Plus 8TB is CMR-based, not SMR, and rated for continuous, always-on, multi-bay operation, which matters more for a business NAS than a single external drive's specs would suggest.
Populating a 4-bay unit
Buy at least 2 matching drives at once for RAID redundancy from day one rather than adding a second drive later once the array is already full of data.
Frequently Asked Questions
How many concurrent users can a small business NAS handle on gigabit Ethernet?
A standard 1GbE connection works fine for document-heavy work with under 5 simultaneous users, but throughput per person drops noticeably once more people are transferring large files at the same time. Upgrading to 2.5GbE or 10GbE, on both the NAS and a matching switch, multiplies per-user throughput for larger or media-heavy teams.
Do I need Active Directory integration for a small business NAS?
Most small businesses eventually migrate from individual NAS logins to centralized directory sync as the team grows past roughly 5 users. It's genuinely useful for managing accounts at scale, but the setup is complex enough that it usually needs IT help to configure correctly the first time.
Does the NAS itself need to be backed up?
Yes. Most guidance treats a NAS only as a backup destination for computers, but ransomware attacks specifically targeting NAS devices are increasing. Set up cloud backup integration for the NAS's own data so a ransomware event or hardware failure doesn't destroy the only copy of your business files.
Do I really need a UPS for a business NAS?
Yes, treat it as a required companion purchase. A power outage that hits mid-write can corrupt a RAID array, and a USB-connected UPS lets the NAS detect the outage and shut down safely before that happens.
What's the difference between Value-tier and Plus-tier NAS warranties?
Value-tier models, like the Synology DS225+ or DS423 in this list, carry a shorter warranty with no enterprise support option. Plus-tier models, like the DS925+ or DS725+, offer longer coverage and an enterprise support add-on, worth the price step up for business-critical data.
Should a small business start with a 2-bay or 4-bay NAS?
If the team is small and unlikely to grow much, a 2-bay unit like the UGREEN DXP2800 covers the basics affordably. If growth is likely, either start with an expandable 2-bay unit like the Synology DS725+ or go straight to a 4-bay model like the DS925+ or UGREEN DXP4800 Plus to avoid a second purchase within a year or two.
