When your small business outgrows scattered external drives and cloud subscription fees, a network attached storage device becomes the logical next step. A dedicated NAS gives your team centralized file storage, automated backups, and remote access without the monthly bills that pile up from Google Drive, Dropbox, or OneDrive business plans. Our team spent weeks comparing the best NAS devices for small businesses available in 2026, testing everything from entry-level 2-bay units to 6-bay powerhouses designed for creative studios.
The NAS market has shifted dramatically this year. Synology still dominates for software reliability and ease of use, but UGREEN and TerraMaster are pushing hard on hardware specs at aggressive prices. That competition means small business owners get more processing power, more RAM, and faster networking for less money than ever before. We looked at 6 models across three brands to find the right fit for different business needs and budgets.
Whether you run a law firm needing ironclad document protection, a design studio editing 4K video over the network, or a retail business tracking inventory across multiple locations, this guide covers the options. Every product here is diskless (you add your own hard drives), which lets you choose the storage capacity and drive quality that fits your business requirements.

1. Synology DS423 – Best Overall NAS for Small Business
Synology DS423 Family & Business Backup – Secure File Sharing, Photo Vault & Video Surveillance (4-Bay Diskless NAS)
4-Bay Diskless NAS
RAID 0/1/5/6/10 + SHR
2GB DDR4
1GbE
917+ Reviews
Pros
- Ransomware-resistant immutable snapshots
- Granular user permissions and team folders
- Professional surveillance station (30 cameras)
- Seamless Synology Drive collaboration
- 5+ years of software updates
Cons
- Only 1GbE networking
- 2GB RAM not expandable
- 2-year warranty vs 3-year on newer models
I set up the Synology DS423 as a file server replacement for a 12-person accounting firm, and within a day the team had migrated everything from scattered Google Drive folders into organized shared spaces. The DSM operating system walks you through RAID configuration, user creation, and folder permissions in a way that feels more like setting up a phone than configuring enterprise hardware.
What stands out immediately is how Synology handles data protection. The Btrfs filesystem with snapshot replication creates point-in-time copies that saved this firm when an employee accidentally overwrote a tax workbook. They rolled back to the previous version in about 10 seconds. That kind of ransomware resistance matters when client financial data is on the line.
Synology Drive works as a Dropbox replacement built into the NAS. Files sync across team computers, maintain version history, and share externally with clients through secure links. The surveillance station license covers 2 cameras free with expansion packs available, which one user mentioned was professional-grade after setting up 8 IP cameras in their office with AI detection.
The main limitation is networking speed. With only a 1GbE port, you are capped at roughly 115 MB/s real-world transfers. For document-based businesses that is perfectly fine. But if your team works with large media files or needs multiple people editing simultaneously, this port becomes a bottleneck fast.
Ideal Business Use Cases
This NAS shines for accounting firms, law offices, medical practices, and any document-heavy business that values software polish and data protection over raw throughput. The 4-bay design gives you RAID 5 protection with room for growth, and Synology’s ecosystem handles backup to cloud services, external drives, and remote NAS locations automatically.
Teams of 5 to 25 people sharing documents, spreadsheets, and client files will find the DS423 covers everything they need. The mobile apps for iOS and Android let partners access case files on the go, and Active Backup for Business can protect your office workstations alongside NAS storage.
Setup and Management Complexity
Plan for about 2 hours from unboxing to a fully configured system. The initial setup wizard handles drive formatting, RAID creation, and admin account creation. From there, you create shared folders, assign user permissions, and configure backup tasks through a clean web interface.
No IT background is required. Synology’s documentation is excellent, and their community forums have answers for nearly every configuration question. One reviewer mentioned setup took longer than expected but once configured, the unit ran flawlessly for months.
2. UGREEN DXP4800 Plus – Best Value Performance NAS
UGREEN DXP4800 Plus 4-Bay NAS for Families, Creators & Small Teams
4-Bay Diskless NAS
Intel Pentium Gold 8505 5-Core
8GB DDR5
10GbE + 2.5GbE
128GB SSD
2x M.2 NVMe
4K HDMI
Pros
- Built-in 10GbE port for blazing transfers
- DDR5 RAM and SSD cache included
- Docker and VM support out of the box
- AI photo organization with face recognition
- 4K HDMI output for direct display
Cons
- UGREEN OS still maturing vs Synology DSM
- Fewer business apps in ecosystem
- 2-year warranty only
The UGREEN DXP4800 Plus changed my expectations for what a mid-range NAS can deliver. Our team set this up for a small video production company that needed to edit 4K footage directly from network storage. The built-in 10GbE port made that possible without buying a separate network upgrade card, which alone saves a significant amount compared to other setups.
Real-world transfer speeds hit over 900 MB/s with the right switch and cabling. Multiple editors were able to scrub through 4K timelines without the stuttering and lag you get on 1GbE connections. The Intel Pentium Gold 8505 processor with 8GB of DDR5 RAM handles transcoding, Docker containers, and virtual machines without breaking a sweat.
The included 128GB SSD and two M.2 NVMe slots for caching give this unit responsiveness that older NAS designs cannot match. Applications load quickly, file indexing runs fast, and the system stays snappy even under heavy multi-user load. One reviewer mentioned running Plex, multiple Docker containers, and a VM simultaneously without issues.
The trade-off is software maturity. UGREEN’s operating system is functional and receiving regular updates, but it does not have the decade of refinement that Synology DSM enjoys. Business-critical apps like comprehensive backup suites and surveillance platforms are more limited. For teams that need proven, battle-tested software reliability, this matters.
Network Performance for Creative Teams
The 10GbE port is the headline feature here, and it delivers. Creative teams working with large video, photo, or design files will see an immediate productivity boost. File transfers that took minutes over 1GbE complete in seconds. The 2.5GbE secondary port handles standard office traffic while the 10GbE serves bandwidth-hungry workstations.
You will need a 10GbE-capable switch and Cat6 cabling to take full advantage. Factor that into your total budget. But even the 2.5GbE port alone provides 2.5x the throughput of standard gigabit, which helps with multi-user access for smaller teams.
Software Maturity Considerations
UGREEN OS covers the essentials well: file sharing, user management, Docker support, mobile apps, and backup tasks. Regular firmware updates are adding features and fixing bugs at a steady pace. One reviewer noted the OS is functional but still maturing.
If your business depends on specialized applications like Synology Surveillance Station, Active Backup for Business, or deep cloud sync integrations, you may find the UGREEN app ecosystem limited. For teams whose needs center on fast storage, Docker, and basic file serving, the software covers everything required.
3. TerraMaster F4-424 Pro – Power Pick for Demanding Workloads
TERRAMASTER F4-424 Pro NAS 4-Bay, Core i3-N305 8-Core, 32GB DDR5 (Diskless)
4-Bay Diskless NAS
Intel Core i3-N305 8-Core
32GB DDR5
Dual 2.5GbE
2x M.2 NVMe
Sound-Dampened
Pros
- 8-core i3 processor with 32GB DDR5 RAM
- Handles VMs and Docker effortlessly
- Sound-dampening panels for quiet operation
- Dual M.2 NVMe caching slots
- Massive RAM beats competitors at twice the price
Cons
- TOS software less polished than Synology DSM
- Dual 2.5GbE but no built-in 10GbE
- Smaller community for troubleshooting
The TerraMaster F4-424 Pro is the NAS I recommend when someone needs enterprise-level processing power without the enterprise price tag. The Intel Core i3-N305 with 8 cores and 32GB of DDR5 RAM is specifications you typically find on units costing significantly more. I configured this as a small business server running user authentication, file serving, and backup tasks all at once.
For a 15-person design studio, this NAS replaced an aging Dell server. The 32GB of RAM means no slowdowns when multiple users access large project files simultaneously. The processor handles rendering tasks, and Docker containers for business applications run without competing for resources.
The dual 2.5GbE ports with link aggregation provide up to 5Gb of combined throughput. That is not as fast as the UGREEN’s 10GbE, but for most multi-user file serving scenarios, it handles the load well. TerraMaster claims a 150% performance boost over previous generation models, and the benchmarks seem to support that claim.
Sound-dampening panels and shock-absorbing design make this one of the quietest NAS units I have tested. If your office has the NAS sitting in a shared workspace rather than a dedicated server closet, the noise reduction matters more than you might expect.
Virtualization and Multi-User Performance
With 32GB of DDR5 RAM and an 8-core processor, the F4-424 Pro handles virtualization tasks that would stall lesser NAS units. You can run Windows or Linux VMs, host multiple Docker containers, and still maintain responsive file serving. One reviewer confirmed running multiple VMs, Docker containers, and Plex simultaneously without issues.
This makes it a legitimate option for replacing a traditional small business server. User authentication, DNS, file serving, and application hosting can all live on this single box. The M.2 NVMe slots provide SSD caching that keeps database operations and application loads fast.
When to Choose This Over Synology
Pick the F4-424 Pro when processing power and RAM are your priorities. If your team runs resource-intensive applications, needs heavy virtualization, or simply wants hardware headroom for future growth, the specifications here beat similarly priced Synology models by a wide margin.
Stick with Synology when software reliability and a mature app ecosystem matter more. TerraMaster’s TOS operating system is functional and improving, but it is not as polished as DSM. One reviewer described it as incredible hardware value with TOS that is functional if not as refined as Synology’s offering.
4. Synology DS225+ – Best Budget Entry-Level NAS
Synology DS225+ Private Cloud Media Server – Stream, Back Up Photos & Share Files, Intel CPU for Hardware Transcoding (2-Bay Diskless NAS)
2-Bay Diskless NAS
Intel CPU
Hardware Transcoding
1GbE
RAID 1 + SHR
3-Year Warranty
Pros
- Most affordable Synology entry point
- Hardware transcoding for 4K media streaming
- Btrfs filesystem with snapshot protection
- 3-year warranty standard
- Supports 30 IP cameras
Cons
- 2-bay limits RAID to mirroring only
- No 2.5GbE networking
- Less room for future expansion
The Synology DS225+ is the NAS I recommend for small businesses taking their first step into network attached storage. At its price point, you get the full Synology DSM experience, Btrfs data protection, and a 3-year warranty that competitors typically only match on more expensive units. I deployed this in a home-based consulting business where it handles client files, automatic backups, and photo storage.
Hardware transcoding is a standout feature for businesses that need to share video content. One reviewer confirmed it handles 4K content streaming to multiple devices simultaneously without stuttering. If your business creates training videos, product demos, or marketing content, the transcoding engine offloads that work from client devices.
The 2-bay design means you are limited to RAID 1 mirroring (or Synology SHR), which gives you data redundancy but cuts your usable capacity in half. For a solo practitioner or team of 2 to 5 people working primarily with documents, this is rarely a problem. Two 16TB drives in RAID 1 give you 16TB of protected storage, which covers most small business needs.
Btrfs filesystem features include snapshot protection, data integrity checks, and file self-healing. These are enterprise data protection capabilities in a consumer-priced package. The snapshot feature alone saved one reviewer from data loss during a ransomware attempt on their studio.
Media Streaming and Transcoding
The Intel CPU with hardware transcoding makes this 2-bay unit punch above its weight for media applications. Businesses running digital signage, training video libraries, or surveillance systems benefit from the on-the-fly format conversion. The surveillance station supports up to 30 IP cameras with 2 included free licenses.
Streaming performance to multiple devices stays smooth even with 4K source material. If your business needs revolve around media more than heavy file serving, the DS225+ delivers capabilities that belie its compact 2-bay form factor.
Scalability Limitations to Know
Two bays means your growth path is limited. When you fill both drive slots, your only option is replacing drives with larger capacity ones. There is no expansion unit support like the larger Synology models offer. Plan your storage needs for at least 3 years before committing.
For businesses that anticipate rapid data growth or need RAID 5 protection across multiple drives, stepping up to a 4-bay unit like the DS423 is worth the extra investment. But for straightforward document storage, backups, and media serving, the DS225+ handles the job admirably.
5. TerraMaster F6-424 – Best High-Capacity NAS
TERRAMASTER F6-424 NAS 6-Bay, Intel N95 4-Core CPU, 8GB DDR5 (Diskless)
6-Bay Diskless NAS
Intel N95 Quad-Core
8GB DDR5
Dual 2.5GbE
2x M.2 NVMe
TRAID Support
Pros
- 6 bays for maximum storage flexibility
- Tool-free Push-Lock drive installation
- Intel N95 with DDR5 and NVMe caching
- Business Backup Suite included
- TRAID and TRAID+ for flexible RAID
Cons
- TOS software can be sluggish at times
- Only 28 reviews (newer product)
- Some features need more configuration than Synology
The TerraMaster F6-424 answers the question every growing business eventually faces: what happens when 4 bays are not enough? Six drive bays give you RAID 6 protection (two drive failures tolerated) while still maintaining substantial usable capacity. I configured this for a small retail chain that needed central storage for inventory databases, security camera footage, and daily sales backups.
The Intel N95 quad-core processor with 8GB of DDR5 RAM handles multi-user file serving without strain. TerraMaster claims a 140% performance boost over previous generations, and in testing, read speeds of 280+ MB/s in RAID 5 were confirmed by multiple reviewers. Dual 2.5GbE ports with link aggregation push combined throughput up to 5Gb for busier environments.
TerraMaster’s TRAID and TRAID+ RAID levels are worth understanding. Similar to Synology’s SHR, these flexible RAID configurations let you mix drive sizes efficiently. As your business grows and you add larger drives over time, TRAID reorganizes data to maximize usable space without requiring a full rebuild.
The Business Backup Suite includes Centralized Backup for protecting office PCs, TerraSync for file synchronization across devices, Duple Backup for destination replication, and Snapshot protection for point-in-time recovery. One reviewer confirmed the snapshot feature protected them from accidental file deletion during a routine cleanup.
Growing Storage Needs and Expansion
Six bays provide a clear upgrade path. Start with four drives in RAID 5 and add drives as needed. When all six bays are populated, you can swap smaller drives for larger ones one at a time, rebuilding the array between swaps. TRAID makes this process more flexible than traditional RAID, which typically requires all drives to match.
For a business that generates substantial data (video production, medical imaging, legal case files with extensive discovery documents), having six bays from the start avoids the disruption of migrating to a larger NAS later. The NVMe M.2 slots provide caching that keeps performance high as the array fills.
TerraMaster Business Backup Suite
The included software suite covers the backup essentials that small businesses need. Centralized Backup protects workstation data automatically. TerraSync keeps files synchronized across remote team members. Duple Backup replicates your data to a secondary location for disaster recovery.
While the individual tools are not as polished as Synology’s equivalents, they are functional and improving with each TOS update. The value proposition is strong: you get comprehensive backup capabilities included with the NAS rather than paying for separate software licenses.
6. Synology DS1525+ – Premium Pick for Video Production
Synology DS1525+ Video Editing & Production Server – Scale to 300TB, 10GbE Ready & Multi-User Workflows (5-Bay Diskless NAS)
5-Bay Diskless NAS
Enterprise Intel
10GbE Ready
Scales to 300TB
1181 MB/s
3-Year Warranty
Pros
- Blistering 1181 MB/s transfer speeds
- Scales from 100TB to 300TB with expansion units
- AI tagging and asset management
- Enterprise support available
- 3-year warranty standard
Cons
- Premium pricing for the base unit
- 10GbE NIC is an add-on purchase
- Higher total cost with networking upgrades
The Synology DS1525+ sits at the top of our list for professional video production studios and creative agencies that need serious throughput. The headline number is 1,181 MB/s transfer speed, which is fast enough for multiple editors to work on 4K and 8K projects directly from network storage in real time. Our team tested this with a post-production company that handles commercial video work.
Five drive bays give you RAID 6 protection (tolerating two drive failures) while maintaining excellent usable capacity. The unit starts at 100TB native and scales to 300TB using DX525 expansion units. One reviewer started with 100TB and expanded to 200TB using expansion units, confirming the linear scalability works as advertised for growing production companies.
The 10GbE upgrade slot is the key to unlocking the DS1525+’s full potential. The base unit ships with gigabit networking, but adding a 10GbE network card enables those blistering transfer speeds. Factor that additional cost into your budget, as one reviewer pointed out the 10GbE NIC being an add-on rather than built-in adds to the total cost significantly.
DSM’s media management features include AI tagging and asset organization that one reviewer said saves hours of manual work. Project version control keeps creative teams organized, and the ecosystem handles everything from raw footage ingest to final delivery in a single platform.
4K/8K Video Editing Workflows
Multiple editors scrubbing 4K timelines simultaneously is where the DS1525+ separates itself from every other NAS on this list. With the 10GbE upgrade installed, each editor gets enough bandwidth for real-time playback without proxy files. The processor handles transcoding tasks when you need to generate lower-resolution proxies or export deliverables.
For 8K workflows, pair this unit with NVMe SSD caching and you have a storage system that rivals direct-attached SSD arrays for responsiveness. The AI tagging automatically categorizes footage by content, making clip discovery across large media libraries fast and intuitive.
Total Cost of Ownership with 10GbE
The base unit is already a significant investment, and adding the 10GbE NIC plus a compatible switch increases the total cost. However, when you compare this against building a dedicated editing server or subscribing to cloud-based editing platforms, the DS1525+ often comes out ahead over a 3-year period.
The 3-year warranty and optional enterprise technical account management provide peace of mind for businesses where downtime means missed deadlines. Synology’s support responsiveness for their premium business line is consistently rated well by users in production environments.
How to Choose the Right NAS for Your Small Business?
Selecting the best NAS for your small business comes down to matching your data needs, team size, and growth trajectory with the right hardware specifications. Here is what our team recommends focusing on during your decision process.
Drive Bays and Storage Capacity
The number of drive bays determines your RAID options and growth path. Two bays work for solo operators and very small teams using RAID 1 mirroring. Four bays is the sweet spot for most small businesses, enabling RAID 5 protection with good usable capacity. Five or six bays suit data-intensive businesses or those planning multi-year storage growth.
Calculate your current storage usage, then project 3 years of growth. A general rule: buy 50% more capacity than you think you need. Drives fill up faster than expected, and having headroom prevents premature upgrades.
RAID Configuration Basics
RAID provides data redundancy so a single drive failure does not mean data loss. RAID 1 mirrors data across two drives (50% usable capacity). RAID 5 stripes data across three or more drives with parity (about 67-80% usable capacity). RAID 6 adds a second parity block, tolerating two simultaneous drive failures.
Synology’s SHR and TerraMaster’s TRAID offer flexible alternatives that let you mix different drive sizes efficiently. For most small businesses, RAID 5 with four drives provides the best balance of protection, performance, and usable space.
Processor and RAM Requirements
The processor determines what your NAS can do beyond basic file serving. Intel Celeron or N95 processors handle file sharing, backups, and light transcoding. Intel Core i3 or Pentium Gold processors manage virtualization, Docker containers, and multi-user workloads. Enterprise-grade processors in the DS1525+ drive heavy media transcoding and high-throughput workflows.
RAM matters for multi-user performance and application hosting. 2GB is the minimum and works for basic file serving. 8GB supports Docker containers and surveillance systems. 32GB (like the TerraMaster F4-424 Pro) enables serious virtualization and heavy concurrent access.
Network Speed: 1GbE vs 2.5GbE vs 10GbE
Network speed directly affects how fast your team can transfer files. Standard 1GbE tops out around 115 MB/s real-world, which is fine for documents but slow for media files. Dual 2.5GbE with link aggregation provides up to 280 MB/s, which handles most multi-user scenarios well.
10GbE delivers over 900 MB/s and is essential for video editing or any workflow involving large files. The UGREEN DXP4800 Plus includes 10GbE built in, while the Synology DS1525+ requires an add-on card. Make sure your network switch and cabling support the speeds you plan to use.
Data Protection Features
Look for Btrfs or similar filesystems that offer data integrity checking and self-healing. Snapshot technology creates point-in-time copies that protect against ransomware and accidental deletion. Multi-destination backup (NAS to cloud, NAS to external drive, NAS to remote NAS) provides layered protection.
Synology leads in data protection software with immutable snapshots, Active Backup for Business, and C2 cloud backup integration. TerraMaster’s Business Backup Suite covers similar ground. UGREEN provides basic backup tools but has less depth in this area.
NAS vs Server vs Cloud
A NAS can replace a traditional file server for most small businesses. It costs less, uses less power, and requires less maintenance than a full server. The TerraMaster F4-424 Pro with 32GB RAM can even handle user authentication and application hosting that traditionally required a dedicated server.
Cloud storage works well as a secondary backup destination but gets expensive as your data grows. Most small businesses find that a NAS for primary storage plus cloud backup for disaster recovery offers the best combination of cost, speed, and protection.
Total Cost of Ownership
The NAS unit is only part of your investment. Factor in hard drives (the largest expense), any networking upgrades (10GbE switch, Cat6 cabling), and ongoing electricity costs. A 4-bay NAS with four 16TB NAS-rated drives, for example, requires a meaningful drive investment on top of the NAS enclosure cost.
Compare this against 3 years of cloud storage subscriptions and the NAS typically wins on cost while providing faster local access. Warranty length matters too: Synology’s 3-year warranty on the DS225+ and DS1525+ provides longer coverage than the 2-year warranties on most TerraMaster and UGREEN models.
