Your phone is full of family photos, your laptop groans under video projects, and cloud subscriptions keep creeping up. A home NAS (network attached storage, basically a private cloud that lives in your house) solves all three problems at once, giving you one place to store, share, and protect everything. The right model depends on how much storage you actually need, how many people stream from it, and whether you want room to grow. The picks below cover everyone from first-time owners to households running creative studios.
A Closer Look At The Lineup
TERRAMASTER F4-425 Pro NAS 4-Bay (Intel N350, 16GB DDR5)
Synology 8 Bay RackStation RS1221+ (Diskless)
Synology DiskStation DS1019+ NAS 5-Bay (8GB DDR3L)
UGREEN NASync DXP4800 GT 4-Bay Desktop NAS (AMD R2514, 8GB DDR4)
Synology DiskStation DS218+ NAS 2-Bay (Diskless)
Synology DiskStation DS920+ NAS 4-Bay (4GB DDR4)
Synology DiskStation DS1621+ NAS 6-Bay (Diskless)
TERRAMASTER F2-425 Plus NAS 2-Bay (Intel N150, 8GB DDR5)
TERRAMASTER F4-424 Pro NAS 4-Bay (Core i3-N305, 32GB DDR5)
More On The Choices That Made The List
Most home NAS units give you one fast network port and a quiet CPU. The F4-425 Pro skips that compromise by pairing an 8-core Intel N350 chip with two 5GbE jacks (gigabit Ethernet ports that handle five times the data of a standard one-gig connection) you can bond together for up to 10Gb of throughput. That kind of bandwidth matters when several family members stream 4K video while a backup runs in the background.
Four front-loading drive bays hold most household libraries, and three M.2 NVMe slots (small, stick-shaped SSDs that plug straight into the motherboard) let you add cache or fast storage pools without eating into the main bays. Compared with the smaller F2-425 Plus later in the list, this Pro model trades compactness for raw horsepower.
What It Does Well
- Bonded 5GbE networking keeps multi-user 4K streaming smooth even during heavy backup jobs.
- Triple M.2 NVMe slots add caching without sacrificing a drive bay, speeding reads for media servers.
- 16GB of DDR5 RAM out of the box handles several Docker containers (lightweight apps that run isolated on the NAS) and a Plex library at the same time.
- The 7W CPU sips power, so leaving it on 24/7 won’t spike your utility bill noticeably.
Worth Bearing In Mind
- Drives aren’t included, and the four-bay chassis works best with matched NAS-grade drives you buy separately.
- You’ll need a managed switch (a network box that lets you combine ports for faster speeds) to actually realize the 10Gb aggregated throughput.
- Firmware updates occasionally require a manual reboot, which can interrupt scheduled backups.

Right Fit For
Creators and households streaming 4K to multiple TVs while running backups and apps in the background will appreciate the breathing room this unit provides.
Swap It Out When
The Synology DS1621+ is a stronger call if you need six drive bays today and want Synology’s mature DiskStation Manager software for fleet management.
Picture a small studio with terabytes of raw footage piling up, or a household that treats the NAS like a digital vault. Either way, eight bays solve the “running out of room” problem in a single box. The RS1221+ is a short-depth rackmount unit, so it fits in tighter AV closets and half-height racks where a full server wouldn’t.
DiskStation Manager (Synology’s operating system that runs the NAS) turns the hardware into a versatile server, and Synology’s ecosystem of backup, sync, and surveillance apps means you can grow into the unit over time. Compared with the desktop DS1621+ further down, this rackmount trades quiet living-room aesthetics for raw expandability.
Bright Spots
- Eight 3.5″ bays hold tens of terabytes in a single RAID array (a configuration that stripes data across drives so one failure doesn’t lose your files).
- Short 2U depth (about 14 inches deep) slides into cabinets a full server can’t.
- DSM software gives you Active Backup, virtualization, and cloud sync without extra licenses.
Trade-Offs To Consider
- Rack fans run louder than a desktop tower, so it belongs in a closet, not on a desk.
- Requires rack rails or a shelf, which adds setup friction for first-timers.
Built With In Mind
Small offices and home studios that already own a rack, or anyone with serious multi-terabyte storage needs, will get the most out of this configuration.
Where A Sibling Pick Shines
The Synology DS1019+ suits living-room use much better if you want Synology software without the rack footprint or fan noise.
Five bays hit a sweet spot that two-bay units can’t. You can run a four-drive SHR (Synology Hybrid RAID) or RAID 5 array, which means one drive can fail without taking your data with it, and still keep a fifth bay as a hot spare ready to rebuild automatically. That kind of fault tolerance used to require an IT department.
The quad-core CPU with AES-NI hardware encryption (a chip-level feature that encrypts data on the fly without slowing transfers) keeps speeds above 225 MB/s even with full-disk encryption turned on, and 4K transcoding works for two simultaneous streams. Compared with the older DS218+ covered later, the DS1019+ adds more RAM and an extra bay for the same living-room-friendly form factor.
Positive Points
- Hardware encryption keeps private data safe without crippling transfer speeds.
- 4K transcoding handles two simultaneous streams, great for a couple of TVs playing different movies.
- 8GB of RAM out of the box supports several apps running side by side.
- Synology’s DSM app ecosystem covers backups, photos, mail, and surveillance without extra fees.
Honest Caveats
- Only 2.5GbE isn’t built in, so fast transfers depend on link aggregation (combining two Ethernet cables for double the speed) through the dual gigabit ports.
- DDR3L RAM is older, and finding compatible upgrades can be a little trickier than DDR4.
Whose Shelf It Belongs On
Streaming households and small offices that want mature software, fault tolerance, and 4K playback without paying for a six-bay unit will find a comfortable home here.
Look Elsewhere When
The Synology DS920+ is a smarter step if you want M.2 caching built in, or pick the TERRAMASTER F4-425 Pro for much faster networking.
Few home NAS units ship with two full 10GbE ports. The DXP4800 GT does, and that one spec changes how a backup feels. Dragging a 50GB video project onto the box takes seconds rather than minutes, which is why editors working from home keep gravitating toward this category of hardware.
The AMD Ryzen R2514 chip handles four cores and eight threads at up to 3.7GHz, and an HDMI output lets the unit double as a media player plugged straight into a TV. The 8GB of DDR4 RAM expands to 64GB, so you can grow into heavier workloads. Compared with the Synology DS920+, this UGREEN trades software polish for raw connectivity.
Reasons It Performs
- Dual 10GbE ports handle multi-gig networks without buying extra adapters or switches.
- HDMI output turns the NAS into a direct-play media box for any monitor or TV.
- RAM scales to 64GB, supporting heavy virtual machines and Docker setups.
- Two M.2 NVMe slots add cache or fast storage pools.
Some Limits To Know
- UGREEN’s NAS software is younger than Synology’s DSM, so you may find occasional rough edges in app polish.
- To use full 10GbE speeds, your switch and client devices need to support it too.

Best Suited To
Home media hubs and creative households that need fast network speeds and an HDMI hookup for direct playback will get a lot of mileage out of this pick.
Not Your Match When
The Synology DS1621+ makes more sense for a buyer who values mature software, longer refinement, and proven reliability over raw port speed.
First-time NAS owners often buy more box than they need. The DS218+ keeps things simple with two bays, a friendly setup wizard, and a desktop chassis that fits next to a router without looking like a server. For a household storing documents, photos, and a modest movie collection, that’s plenty of room.
The dual-core CPU with AES-NI encryption keeps encrypted reads above 113 MB/s, and the Btrfs file system (an advanced file format that protects against silent data corruption and supports point-in-time snapshots) supports up to 65,000 system-wide snapshots (saved copies of your data you can roll back to if something goes wrong). Compared with the bigger DS920+, this unit costs less and runs cooler, but you lose expansion room.
Strong Points
- DSM setup walks you through user accounts, shares, and apps in under an hour.
- Btrfs snapshots protect against accidental file deletion or ransomware-style corruption.
- Compact, quiet enclosure works on a desk or shelf.
Points To Keep In Mind
- Two bays cap your storage and limit RAID options to mirroring (copying the same data to both drives, so you only get half your total capacity for safety).
- 4K transcoding tops out at two concurrent streams, which may feel tight for busy media households.

A Better Fit Elsewhere
The TERRAMASTER F2-425 Plus is a stronger call if you want modern DDR5 RAM and a 2.5GbE option in a similar two-bay footprint.
Many households start with two drives and a vague plan, then outgrow it within a year. The DS920+ plans for that moment with a scalable storage design: add a Synology DX517 expansion unit later, and you can stretch to nine drives without migrating data. That’s real headroom.
Two M.2 SSD slots (small internal SSDs that act as a turbo boost for the system) sit underneath, ready to accelerate read-heavy tasks like photo syncing without using up the four main bays. For most families, this balance of capacity, expandability, and software polish hits the right note. Compared with the older DS1019+, the DS920+ adds newer DDR4 memory.
What Pays Off
- Expansion chassis support means you can double storage without rebuilding the array.
- Built-in M.2 slots accelerate hot data without sacrificing main drive bays.
- DSM’s Hyper Backup covers cloud, local, and offsite destinations in one tool.
Small Caveats
- 4GB of RAM out of the box is workable but light for multiple apps and containers.
- Realizing the expansion option requires buying a separate DX517 unit, which adds cost.

Who Will Love This
Growing families that want a polished software experience and room to add capacity over time will feel right at home.
Consider Something Else When
The TERRAMASTER F4-425 Pro is the better match for households prioritizing 10Gb-class networking speed over software maturity.
Once you start editing video or backing up multiple computers nightly, two or four bays fill up surprisingly fast. Six bays give you enough capacity to grow into without juggling external drives, and the DS1621+ pairs that with Synology’s strongest app ecosystem. You can add two DX517 expansion units and reach sixteen drives total, which is more headroom than most homes will ever need.
Compared with its predecessor, the DS1621+ roughly doubles 4K random read IOPS (input/output operations per second, a measure of how many small file requests the system can handle at once) and adds dual M.2 slots for SSD cache. For most media households, that translates to a snappier feel under load.
Everyday Wins
- Six bays handle today’s library and tomorrow’s expansion without re-architecting.
- Dual M.2 slots cache hot data, speeding photo and video apps noticeably.
- Synology’s Active Backup suite covers PCs, servers, and cloud destinations at no extra cost.
- Optional 10GbE upgrade (sold separately) keeps the unit relevant for years.
Possible Compromises
- 10GbE networking isn’t built in, so heavy transfer speeds require buying a PCIe network card.
- The desktop tower runs warm under sustained load, so plan airflow around it.
Who Should Grab It
Media pros, photographers, and busy households managing large photo or video libraries across multiple devices.
Reach For A Different Pick When
The UGREEN NASync DXP4800 GT fits better for buyers who want dual 10GbE built in and an HDMI output for direct media playback.
Two-bay NAS units used to mean compromise: a slow CPU, modest RAM, and a single gigabit port. The F2-425 Plus refuses that bargain. It runs an Intel N150 quad-core chip, ships with 8GB of DDR5, and stashes three M.2 SSD slots inside, which is unusual in a chassis this small.
Dual 5GbE ports give the unit more network headroom than most two-bay boxes, and the all-SSD option is appealing for people who want quiet operation in a living room or bedroom. Compared with the older Synology DS218+ earlier in the list, this TERRAMASTER brings far newer internals to the same compact footprint.
A Strong Showing
- Three M.2 slots allow all-SSD storage pools or dedicated cache without using main bays.
- Modern DDR5 RAM improves app responsiveness compared with older DDR3L units.
- Dual 5GbE ports add real headroom for fast transfers on a 2-bay box.
Where It May Fall Short
- Two main bays limit traditional HDD capacity, so large media archives may outgrow it fast.
- To benefit from 5GbE, your network gear and client devices need to support that speed.

Skip It When
The Synology DS1019+ is the more sensible pick for households that need five or more bays or prefer the more mature DSM app ecosystem.
Most home NAS units top out at modest RAM and a quiet CPU, because most households don’t need more. The F4-424 Pro lives in the other camp: an 8-core Core i3-N305 chip, 32GB of DDR5, and an integrated UHD graphics engine capable of driving 4K streams. It’s essentially a small server wearing NAS clothes.
Four drive bays plus dual M.2 slots give you a flexible mix of capacity and speed, while dual 2.5GbE ports handle modern home networks. For households running virtual machines, a small home business, or heavy Docker workloads, the headroom is meaningful. Compared with the Synology DS1621+ above, this TERRAMASTER trades six bays for far more raw compute.
Noteworthy Benefits
- 32GB of DDR5 RAM supports heavy multi-app use without breaking a sweat.
- 8-core CPU handles virtual machines, transcoding, and backups running simultaneously.
- Integrated UHD graphics assist 4K transcoding without overloading the CPU.
- Dual 2.5GbE ports aggregate for 5Gb total throughput on capable networks.
Potential Sticking Points
- 32GB of RAM is non-upgradable, so you’re locked into this configuration from the start.
- Four bays cap your raw storage compared with the six-bay Synology DS1621+ for a similar spend.
Who It Suits Best
Home business owners, prosumers, and tech enthusiasts running VMs or many containers alongside media and backup tasks.
Another Choice May Suit
The Synology DS1621+ is worth a look for shoppers who want more drive bays and a longer track record of software refinement at the cost of CPU power.
What To Weigh Before Picking A Home NAS
Drive bay count sets the ceiling for everything else. Two bays work for document and photo backups in a small household, while four to six bays give you room for media libraries, surveillance footage, and future growth. If you anticipate doubling your storage in three years, choosing one tier higher now avoids a migration headache later.
CPU and RAM determine how many things the box can do at once. A NAS used solely for file storage does fine with a modest processor, but the moment you add 4K transcoding, virtual machines, or several Docker containers, an 8-core chip with 16GB or more of RAM pays for itself. DDR5 memory is faster and more future-proof, though DDR4 still runs most apps without complaint.
Networking speed matters more than people expect. Gigabit Ethernet caps transfers at about 110 MB/s in real conditions, which feels slow when moving hundreds of gigabytes. Look for 2.5GbE, 5GbE, or 10GbE ports if your switch and computers support them, since the upgrade transforms how backups feel day to day.
Software ecosystem is the long-game factor. Synology’s DSM is the most polished option with the deepest app catalog, while TERRAMASTER and UGREEN are catching up with faster hardware. If you value plug-and-play apps, that maturity may matter more than raw port speed.
Pitfalls Shoppers Hit And How To Dodge Them
Buying drives that aren’t NAS-rated. Desktop drives can fail faster under 24/7 operation. Choose NAS-specific drives from the start, and you avoid the most common cause of early data loss.
Underestimating the network. Even a powerful NAS bottlenecks at a gigabit port, leaving its CPU and SSDs idle. Match the NAS to your switch and client hardware, or the speed you paid for never shows up.
Ignoring backup strategy. A single NAS, even with RAID, isn’t a complete backup. Plan for an offsite copy, whether that’s a cloud service, a second NAS, or rotated external drives, and your data survives even the worst-case scenarios.
Skipping RAM and expansion. Many people buy just enough RAM for day one, then run out as they add apps. Choose a unit with upgrade room, or with more RAM than you currently need.
Frequently Asked Questions
How much storage do most households actually need?
For a family of four storing photos, documents, and a moderate movie collection, 8TB to 16TB of usable space covers most situations. Heavy video editors or photographers may want 32TB or more to avoid constant pruning.
Do I really need RAID?
RAID protects against a single drive failure, which is valuable, but it isn’t a substitute for a real backup. Pair your RAID array with an offsite or cloud copy for complete protection.
Can a NAS replace cloud storage entirely?
For households with decent upload speeds, yes, though initial setup takes more effort than signing up for a cloud service. The long-term savings on subscription fees often pay back the hardware cost within a few years.
How loud are these units in a living room?
Most desktop NAS enclosures run quietly, though spinning hard drives add a constant low hum. For silent operation, look for an all-SSD configuration like the TERRAMASTER F2-425 Plus.
Is setup hard for someone non-technical?
Synology’s DSM and most modern NAS operating systems walk you through the process with friendly wizards. First-timers comfortable installing a smart home device should manage fine.
Wrap Up
The right home NAS depends on what you store, how many people use it, and whether you want room to grow. Two-bay units cover simple backups, four-bay models handle most families, and six-bay or eight-bay boxes serve creative households and small offices. Match the hardware to your real needs rather than the most expensive option, and you’ll end up with a private cloud that quietly does its job for years.
