A NAS (network-attached storage) device fixes that. It centralizes files, backs up automatically, and lets your team collaborate without paying for a full IT department. This guide covers the best NAS devices for small business in 2026, what to look for before buying, and how a local partner like Epic IT Solutions helps get it set up right.
TL;DR
- Centralize files, automate backups, and give small teams secure remote access from one box
- Match the job: budget 2-bay units for basics, expandable 4-5 bay systems when you need RAID room to grow
- Rank capacity, RAID, network speed (1GbE vs 2.5/10GbE), and business apps over brand hype
- Configure RAID, user permissions, and backup jobs correctly on day one—or pay for cleanup later
Overview of NAS Storage in the Small Business Market
A NAS is a dedicated, network-connected device that centralizes file storage and sharing for multiple users. According to the Storage Networking Industry Association, NAS devices connect to a network and provide file-access services at lower cost and complexity than traditional storage area networks.
SMB-class NAS sits between consumer drives and enterprise arrays: more capable than a single external hard drive, far simpler than a full storage array. These systems are built for small teams without dedicated IT staff and typically include:
- 2–5 drive bays for expandable capacity
- RAID redundancy to protect against drive failure
- Snapshot protection for quick file recovery
- Remote access for off-site sharing and work
Below are the top NAS picks for small businesses, based on specs, RAID support, and real-world value.
Best NAS Devices for Small Business
Picks are ranked by performance, scalability, RAID support, and overall value for small business use cases.
Synology DiskStation DS1525+
The DS1525+ is a 5-bay NAS built for businesses that expect to grow. It supports Synology's Hybrid RAID (SHR) along with RAID 0/1/5/6/10, and can expand to 15 total bays using add-on units.
What sets it apart:
- DSM OS with a clean admin UI that most small-business teams can run without a full-time specialist
- Dual 2.5GbE ports, with an optional 10GbE upgrade, for steady multi-user throughput
- Broad app catalog for backup, surveillance, and light virtualization
| Bays | RAID Support | Best For |
|---|---|---|
| 5 (expandable to 15) | SHR, RAID 0/1/5/6/10 | Scaling small businesses |
QNAP TS-464
A 4-bay NAS with a strong app ecosystem and hardware transcoding, well suited to small offices that need file storage plus media services.
- Two M.2 slots and a PCIe expansion slot for caching or future upgrades
- Dual 2.5GbE networking included out of the box
- Solid fit when one box needs to handle shares, apps, and light media work
| Bays | RAID Support | Best For |
|---|---|---|
| 4 | JBOD, RAID 0/1/5/6/10 | Multi-purpose small office server |
Asustor Lockerstor 4 Gen 3 (AS6804T)
This is the speed option. The AS6804T packs two 10GbE and two 5GbE ports, an AMD Ryzen Embedded processor, and M.2 NVMe caching slots. It handles demanding workloads well, but only pays off if your switches and workstations can use multi-gigabit speeds.
| Bays | RAID Support | Best For |
|---|---|---|
| 4 | RAID 0/1/5/6/10 | Speed and expandability |
QNAP TS-233
An affordable 2-bay NAS for very small teams that need centralized storage and basic backup. Setup is simple, and file transfer performance is solid for the price.
- App selection covers core backup and file-share needs
- RAM fixed at 2GB, so heavy app stacks are a poor fit
- Networking tops out at 1GbE
| Bays | RAID Support | Best For |
|---|---|---|
| 2 | JBOD, RAID 0/1 | Budget-conscious startups |
Buffalo TeraStation (TS3020 Series)
Buffalo's TeraStation line focuses on straightforward setup and reliable bulk storage at competitive per-terabyte pricing. It offers Active Directory integration and consistent performance for basic file sharing. One caveat: the older TS3000 series is discontinued, so confirm you're buying current TS3020 inventory with active firmware support.
| Bays | RAID Support | Best For |
|---|---|---|
| 2-4 | RAID 0/1/5/6/10, JBOD | Simple, no-frills file storage |
How We Chose the Best NAS Devices
We ranked devices on what small businesses actually need day to day, not brand recognition alone:
- RAID and data redundancy
- Network speed for real office workloads
- Room to scale past year one
- App ecosystem for backup, sync, and remote access
That lines up with PCMag's testing methodology, which also weighs bays, CPU/RAM, remote access, and security alongside raw performance.
We screened out setups that match the mistakes small businesses make most often:
- Buying single-bay units with zero redundancy, so one drive failure means total data loss
- Ignoring growth and outgrowing a 2-bay system within a year or two
- Choosing 10GbE hardware without a switch or clients that can use it
Ease of management and vendor support matter as much as specs. A NAS that's hard to monitor or slow to patch becomes a liability, especially when you have no in-house IT.
Why Small Businesses Need Professional NAS Setup and Support
Buying the right hardware is only half the job. Proper RAID configuration, user permissions, and backup scheduling all require technical know-how most small business owners simply don't have time for.
RAID is not backup. RAID protects against a failed drive, not accidental deletion, ransomware, or theft — a security best practice confirmed across QNAP's own product security guidance. A proper setup still needs a separate 3-2-1 backup strategy: three copies, two media types, one offsite.
Misconfigured NAS devices are a common cause of data loss and security gaps, particularly for owner-run businesses without dedicated IT staff. Common gaps include:
- Default admin accounts left active
- No multi-factor authentication or login lockout
- Direct internet exposure instead of VPN access
- Untested backups that fail when you actually need them
Closing those gaps is where professional setup pays off. Epic IT Solutions acts as a personal IT department for businesses across North Central Florida, Orlando, Tampa, and Jacksonville.
Through Server Installation & Management and Backup Solutions (Cloud & Local), Epic IT handles centralized file sharing, secure data backup, and network infrastructure, on-site or remote. Backups use 256-bit AES encryption and SSL transmission, with HIPAA- and FINRA-compliant encryption and offsite storage in SSAE 16 Type II-compliant datacenters.
Conclusion
The best NAS is the one that matches your data volume, growth plans, and budget. Before buying, evaluate scalability, RAID redundancy, and how well the vendor's app ecosystem supports backup and remote access.
Once you've picked the hardware, setup matters as much as the hardware. If you'd rather not handle RAID configuration and backup scheduling yourself, contact Epic IT Solutions to help select, install, and maintain the right NAS solution for your business.
Frequently Asked Questions
How much does it cost to run a NAS?
Hardware runs from about $200–$400 for a 2-bay unit to $1,000+ for a 5-bay system, before you add drives. Electricity is minor: a typical unit costs roughly $17 to $72 per year running 24/7 at average U.S. residential rates.
Which NAS storage is best for small businesses?
It depends on team size and growth plans. Very small teams do fine with a budget 2-bay like the QNAP TS-233, while growing businesses benefit from the Synology DS1525+'s scalability and RAID flexibility.
How long will an SSD last in a NAS?
Endurance varies widely by model. A 500GB WD Red SA500 is rated for 350 TBW, while some 3.84TB NAS SSDs exceed 7,000 TBW. Heavier write workloads shorten lifespan, so match capacity and rating to your usage.
What is RAID and why does it matter for a NAS?
RAID combines multiple drives into one logical unit, spreading data so the system survives a drive failure. It's essential for business continuity, but it doesn't replace a real backup.
Can a NAS replace a traditional server for a small business?
For file sharing, backup, and light workloads, yes. A NAS is simpler to set up and manage. Businesses running databases, custom applications, or heavy virtualization still need a traditional server's flexibility.
How do I keep NAS data secure from ransomware and unauthorized access?
Disable default admin accounts, enable multi-factor authentication, and never expose the NAS directly to the internet. Use a VPN instead. Keep firmware updated and test backup restores regularly to confirm they actually work.
