Centralized storage has quietly shifted from a server-room curiosity into a household essential. Anyone juggling years of photos, 4K video projects, or a growing small business knows the pain of scattered external drives. A well-chosen NAS keeps files accessible from every device, backs up automatically, and stays online even when your laptop is closed. The picks below cover home offices, creative studios, and rack-ready environments where uptime really matters.
The Lineup, Simplified
Synology RS1221+ 8-Bay RackStation (Diskless)
Synology RS822+ 4-Bay RackStation (Diskless)
UGREEN DXP4800 GT 4-Bay Desktop NAS
UGREEN DXP4800 Plus 4-Bay Desktop NAS

Asustor AS5404T 4-Bay NAS
Asustor AS5402T 2-Bay NAS
Taking A Closer Look At The Options
The RS1221+ lands at the heavy end of Synology’s rackmount lineup, built for businesses that treat storage as infrastructure rather than a desk-side accessory. Its 2U short-depth chassis slips into cabinets where full-length servers won’t fit, which matters in older server closets and small IT rooms.
Compared to the RS822+ that follows in this roundup, this unit doubles the bay count and trades the entry price for genuine scale. Synology’s DiskStation Manager handles backups, file syncing, and surveillance in one interface, so the hardware rarely needs babysitting once configured.
Notable Upsides
- Eight hot-swappable bays accommodate tens of terabytes across RAID configurations
- Short-depth 2U chassis fits cramped server closets and wall-mount racks
- DiskStation Manager ecosystem covers backups, virtualization, and surveillance out of the box
- ECC memory support (where equipped in this series) protects against silent data corruption
Things To Consider
- Diskless purchase means budgeting separately for enterprise-rated drives
- 2U rack format requires a proper rack or shelf, not a desktop placement
- Setup complexity runs higher than consumer 2-bay units like the DS225+
Quick Facts
Who It Suits Best
Small businesses and IT teams running virtual machines, file shares, or surveillance workloads on dedicated infrastructure.
Where Another Pick Suits Better
Home users without a rack should consider the Synology DS225+ instead, since its 2-bay desktop form factor needs no special mounting.
The RS822+ brings rackmount discipline to branch offices that don’t need the eight-bay scale of the RS1221+. Its 1U chassis keeps rack space lean, which helps when you’re paying by the unit in a colocation rack.
For shops standardizing on Synology’s DSM interface, the learning curve carries over directly from the larger units. That makes onboarding a new technician less of a gamble.
Good Reasons To Consider
- Sequential throughput above 2,000 MB/s read for fast backup windows
- Four 1GbE ports enable link aggregation and network failover on a budget
- Optional 10/25GbE expansion cards future-proof the network side
- Scales to eight drives with one RX418 expansion unit when needs grow
Worth Noting
- 1U rack form factor demands rack rails or a shelf tray for proper mounting
- SSD cache is an add-on, not included at base configuration
- 1GbE baseline may bottleneck multi-user video workflows without expansion

Consider Something Else When
Creatives wanting NVMe cache out of the box should look at the UGREEN DXP4800 GT, which ships with two M.2 slots ready to use.
The DXP4800 GT is UGREEN’s take on a prosumer powerhouse, pairing an AMD Ryzen Embedded R2514 with two 10GbE ports. That’s a rare combination outside rackmount territory, and it puts serious throughput on a desktop.
Next to Synology’s rack units, this is a totally different conversation: no rails, no rack depth to worry about, just a chunky tower that lives next to your monitor. The 4K HDMI output also doubles it as a media box if you want a Plex-style setup.
Well-Handled Touches
- Dual 10GbE ports enable multi-gig transfer speeds for video editors moving terabytes
- Two M.2 NVMe slots add cache or fast storage tiers without taking drive bays
- AMD Ryzen R2514 with 8GB DDR4 (expandable to 64GB) handles Docker and VMs comfortably
- 4K HDMI output makes it useful as a living-room media player too
Trade Offs
- Diskless means separate spend on NAS-rated drives, which adds up quickly
- UGREEN’s NAS software ecosystem is newer than Synology’s, so third-party app support varies
- Two 10GbE ports require a compatible switch to fully exploit, adding hidden cost
Best Suited To
Power users with multi-gig networking, video editors, and smart-home enthusiasts who want desktop form without rack noise.
Look Elsewhere When
Buyers wanting a battle-tested software experience should consider the Synology DS225+ for its mature DiskStation Manager.
The DXP4800 Plus slots into UGREEN’s desktop lineup as a balanced pick: Intel Pentium Gold 8505 silicon, DDR5 memory, and a built-in 128GB SSD for the OS. That last detail trims boot times and keeps the drive bays free for bulk storage.
Where the DXP4800 GT pushes toward extreme throughput, this Plus model focuses on everyday office use. You still get one 10GbE and one 2.5GbE port, which is more than enough for most file-share workflows.
Features That Help
- Intel Pentium Gold 8505 (5 cores) handles Docker containers and small virtual machines comfortably
- 8GB DDR5 RAM provides headroom for multitasking apps
- Built-in 128GB SSD separates the operating system from bulk drive bays
- 4K HDMI output supports direct media playback to a monitor or TV
Points To Note
- Capacity caps around 144TB require verified-compatible drive lists that change over time
- 10GbE is single-port, so no link aggregation on the fastest interface
- Software updates cadence is improving but still trails established brands in third-party testing
Technical Highlights
Perfect Match For
Small offices running shared file services, lightweight virtualization, or cross-platform collaboration tools.
A Better Fit Elsewhere
Developers needing more compute headroom will find the UGREEN DXP4800 Pro a stronger match with its Intel Core i3.
The DXP4800 Pro is UGREEN’s developer-grade desktop unit, built around an Intel Core i3-1315U. That CPU is a real step up from the Pentium Gold in the Plus model, and it shows when you’re running virtual machines or compiling code on the box itself.
For IT pros, the appeal is having enough horsepower to treat the NAS like a small workstation. The built-in 128GB SSD and dual M.2 slots give you room to separate hot and cold storage tiers cleanly.
Noteworthy Benefits
- Intel Core i3-1315U handles multiple VMs and Docker stacks without thermal throttling
- 10GbE plus 2.5GbE ports give flexibility for mixed network environments
- Built-in 128GB SSD plus two NVMe slots allow layered storage strategies
- Diskless configuration lets you pick drives sized to your workload
Less Ideal Details
- Four-bay ceiling limits raw capacity compared to six- or eight-bay alternatives
- Higher sustained CPU draw means a slightly louder fan profile under load
- Total cost rises quickly once NVMe cache drives and NAS HDDs are added
Who Should Grab It
Developers, IT professionals, and power users who want workstation-class compute inside a NAS chassis.
Skip It When
Households looking for quiet operation should consider the Synology DS225+ instead, which stays unobtrusive in a living room.
The DS225+ is Synology’s mainstream home-and-family pick, a 2-bay unit with hardware transcoding built in. That last bit matters: it means Plex and similar media apps can convert 4K video on the fly without choking the CPU.
Compared to the rackmount RS822+, this is the approachable sibling. The footprint fits a bookshelf, the fan stays quiet, and DiskStation Manager gives first-time owners a polished interface to learn on.

- Drive cost multiplies when filling four bays with NAS-rated HDDs
Built With In Mind
Home offices and small studios that want four-bay scale without paying for Intel silicon or rack rails.
Swap It Out When
Users planning to run virtual machines should step up to the Asustor AS5404T for its Intel CPU and NVMe slots.
The AS5404T jumps up to an Intel Celeron N5105 quad-core and adds four M.2 NVMe slots, a combo you rarely see at this tier. It’s built for users who treat the NAS as a hybrid storage and streaming platform.
Compared to the Drivestor 4 above, you’re trading a quieter entry-level price for more CPU muscle and cache potential. Live streamers and gamers benefit most from the NVMe caching layer.
The Value In It
- Intel N5105 quad-core at 2.0GHz handles multi-user streaming without lag
- Four M.2 NVMe slots allow extensive SSD caching or all-flash storage
- Two 2.5GbE ports support link aggregation for higher sustained throughput
- 4GB DDR4 RAM provides more headroom than the 1GB Drivestor models
Some Limits To Know
- Filling four M.2 slots with NVMe drives raises the total cost substantially
- ADM app catalog lags Synology’s, particularly for niche media tools
- Fan noise climbs under sustained cache-heavy workloads
Whose Shelf It Belongs On
Live streamers, gamers, and small studios wanting NVMe caching in a desktop NAS without rack hardware.
Not Your Match When
Quiet operation matters most: the Synology DS225+ stays more discreet on a bookshelf for typical home media use.
The AS5402T takes the silicon from the AS5404T and trims it into a 2-bay chassis. You keep the Intel N5105 and four M.2 slots, but lose the extra drive bays, which makes the unit notably more compact.
For small creative studios that prize fast cache over raw capacity, this is a tidy middle ground. The 2.5GbE dual-port setup also lets you aggregate bandwidth for editing directly from the NAS.
Everyday Wins
- Intel N5105 quad-core CPU handles video transcoding and small VMs cleanly
- Four M.2 NVMe slots allow hybrid caching strategies even in a 2-bay chassis
- Two 2.5GbE ports support aggregation for sustained multi-stream workloads
- 4GB DDR4 RAM runs ADM apps smoothly out of the box
What To Weigh
- Two-bay RAID 1 halves usable capacity, so expansion requires external units
- NVMe drives for all four slots push the configuration cost upward fast
- Tool-less trays are convenient but feel lighter than Synology’s metal construction
The Right Fit
Small creative studios and editors who want NVMe cache and Intel CPU in a compact 2-bay desktop unit.
A Better Fit Elsewhere
Buyers needing more drive bays from the Asustor stable should look at the AS5404T, which doubles storage headroom.
Factors To Weigh Before Choosing A NAS
Drive bay count sets the ceiling for capacity, but real-world performance depends on what sits behind them. A 2-bay unit like the Synology DS225+ suits families mirroring a few terabytes of photos. A four-bay enclosure lets you run RAID 5, balancing capacity against redundancy. Eight-bay rackmounts only earn their cost when you’re storing tens of terabytes or running multiple concurrent users.
Network speed matters more than people expect. A Gigabit NAS bottlenecks quickly when several users stream or back up at once. Multi-gig ports (2.5GbE, 10GbE) on picks like the UGREEN DXP4800 GT and Synology RS822+ future-proof throughput, but only if your switch and cabling support it.
CPU and RAM dictate what the NAS can do beyond file serving. Intel chips with hardware transcoding, found in the DS225+ and AS5402T, convert video on the fly for streaming. More RAM means smoother Docker, VMs, and multi-user workloads. AMD and Intel Core i3 options like the UGREEN DXP4800 Pro unlock workstation-class tasks.
Software ecosystem matters for long-term happiness. Synology’s DiskStation Manager is the most mature, with the broadest app catalog. UGREEN and Asustor cover essentials well but trail on niche apps. Plan on living inside the chosen interface for years.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
Underestimating drive costs is the classic trap: every NAS here ships diskless, and four NAS-rated HDDs can equal the price of the enclosure. Many first-time buyers also skip RAID planning and later regret single-drive setups that fail without warning. Ignoring network bottlenecks frustrates people who expect Gigabit-class speeds from a 10GbE-capable unit.
What Separates Premium From Basic
Premium NAS units add features that earn their cost in specific scenarios: ECC memory for data integrity, 10GbE networking for high-throughput workflows, hardware transcoding for media servers, and scalable chassis for growing storage. The Synology RS1221+ and UGREEN DXP4800 GT carry these premiums for users who genuinely need them. Entry-level picks like the Asustor AS1202T serve lighter workloads at friendlier prices.
Frequently Asked Questions
How many drive bays do I really need?
Most households manage fine with two bays running mirrored storage. Four bays make sense once you’re storing tens of terabytes or want RAID 5’s balance of capacity and redundancy. Eight-bay rackmounts are reserved for small business workloads.
Do I need 10GbE networking at home?
Not usually. Multi-gig ports on picks like the UGREEN DXP4800 GT help video editors and heavy multi-user households. For typical backup and streaming duties, 2.5GbE or Gigabit suffices.
What’s the advantage of hardware transcoding?
A CPU with hardware transcoding, like the Intel chip in the Synology DS225+, converts video formats on the fly without maxing out the processor. This matters for Plex-style streaming to phones and TVs with mixed codec support.
Can I mix drive brands and sizes?
NAS operating systems tolerate mixed drives, but RAID arrays usually default to the smallest drive’s capacity. Match drive sizes when parity matters, and stick with NAS-rated models designed for 24/7 operation.
How long do NAS drives typically last?
NAS-rated drives commonly run for five to seven years under constant use. Most owners replace drives on a rolling schedule rather than waiting for failures, and rebuilding RAID arrays with modern drives usually completes in under a day.
Closing Remarks
The right NAS depends on how much storage you actually need, how many people hit it at once, and whether you care more about silence or raw speed. Home users get the most from a polished 2-bay or 4-bay desktop unit, while small businesses benefit from rack-ready units with redundant power and ECC support. Match the hardware to the workload, budget for drives, and pick the software ecosystem you can live with for the long haul.
