How To Choose The Best 2TB NAS Device
You want a 2TB NAS device so every computer, phone, or TV on your home network can reach the same hard drives—no more juggling USB sticks. A NAS (Network Attached Storage) is a mini-server that plugs into your router. Your main choice is how much you value data safety versus how much you want to tinker.
The Safety Net: RAID and Drive Bays
Your biggest decision is one drive bay versus two. A 1-bay unit with a 2TB drive gives you 2TB of space, but if that drive fails, your data is gone. A 2-bay unit running RAID 1 (a mode that writes the same data to both drives) gives you 2TB of usable space with an automatic backup—if one drive dies, the other still holds your files.
Speed and Your Daily Reality
Transfer speed decides whether backing up feels instant or like watching paint dry. A basic NAS might move files at around 17 to 24 MB/s (megabytes per second), which is fine for documents and family photos. Newer models with faster processors and DDR3 memory can hit much higher rates, which matters if you regularly move large video files between machines.

In‑Depth Reviews
1. BUFFALO LinkStation 710 2TB 1-Bay NAS
A slim metal box that hides 2TB of storage inside a desktop-friendly frame.
This single-bay unit is the most straightforward pick here — plug the included Cat 6A ethernet cable into your router, and the 2TB drive inside becomes shared storage for every computer on your network. It is the smallest footprint of the group at 8.07″D x 1.77″W x 5.02″H, so it tucks onto a shelf or beside a desk without dominating the space.
This pick leans on simplicity. There are no RAID settings to learn because there is only one drive, and Buffalo includes NAS Navigator software to automate backups from multiple computers. The closed system reduces vulnerabilities from third-party apps, and SSL encryption (a security protocol that scrambles data during transfer) keeps file transfers secure—real confidence for a personal cloud you access without monthly fees..
The honest catch is reliability. Buyers report “Device failed within 6 months; clicking sounds dismissed by support,” and the recurring theme across owners is that some units run quietly for years while others fail early. One owner saw 80 MB/s on Windows but only 30 MB/s on a Mac Mini M1, and the fan is noticeably loud during backup jobs — a trade-off to accept if you want this price point.
Data safety note: Because it has one drive bay, there is no built-in redundancy. If the drive fails, the data on it is gone unless you back it up elsewhere.
Who it fits: A single-computer household that wants a no-frills, subscription-free cloud without paying for a second drive bay.
Reach for this if: you value the smallest possible footprint and don’t mind a single point of failure.
Look elsewhere if: your files are irreplaceable — you want a second bay for mirrored safety.
2. BUFFALO LinkStation 220 4TB 2-Bay NAS
Two 2TB drives working as one safety net, ready in about five minutes.
Setup is the thing that wins people over here. — reviewers describe a 5-minute install with a simple web interface and quick DLNA setup for streaming to a Roku or TV. The unit ships with two 2TB drives configured in RAID 1, which means you get 2TB of usable capacity and every file is automatically written to both disks.
That dual-drive layout is the defining advantage over the single-bay LinkStation 710 above. If one drive fails, the other still holds your complete data. Owners who have kept this unit since 2014 report it as reliable with no dropouts, and the 4TB total capacity leaves room to replace drives with larger ones (2T to 4T) as your collection grows.
The trade-off is speed and interface. Transfers run around 17 MB/s single and 24 MB/s dual, which is noticeably slower than newer units, and the bundled backup software leaves some owners unimpressed. Time Machine on Mac works immediately, though the drive can sleep and disconnect, requiring a manual reconnect in Finder now and then.
Balance of price and safety: No other pick gives you two bays and automatic mirroring at this value tier, which is why it earns the budget-safety crown.
The slowness reality: Large video backups will test your patience — this is a set-and-forget unit, not a speed demon.
Pick it for: a home that wants mirrored data protection without spending premium money.
Skip it for: heavy media editors who need fast multi-gigabyte transfers every day.
3. BUFFALO LinkStation 720 4TB 2-Bay NAS
The modern upgrade that syncs with Dropbox, Azure, and OneDrive from one box.
This is the step-up model Buffalo positions against its own older LS 200 line. It keeps the same 2-bay RAID 1 layout — so you still get 2TB usable out of the 4TB total — but adds macOS 26 compatibility and hybrid cloud integration with Dropbox, Azure, and OneDrive for extra flexibility.
The added reach matters if you already live in the cloud. Instead of choosing between local and online storage, this unit syncs with those services to create a hybrid setup, giving you data security and scalability without juggling multiple accounts. The metal enclosure and tower mounting keep it stable on a desk, and the included Cat 6A cable supports fast wired connections.
What holds it back is a mixed reliability record. Owners mention easy, smooth setup and working transfers, yet others describe a unit that lost power and became unresponsive after two months, with support slow to respond. An occasional DLNA issue for streaming to TVs is the most common recurring gripe — a minor annoyance if you mainly use the NAS for backups.
What you gain
- Hybrid cloud sync with three major services
- RAID 1 mirroring for automatic backup
- Modern macOS 26 compatibility from the start
Where it stumbles
- Mixed reports of units failing after a few months
- DLNA streaming to TVs can break after updates
- Customer support described as unresponsive by some
Grab it for: the cloud-sync convenience and modern OS support — a genuine step up from the 220.
Think twice if: you need bulletproof reliability; the history here is more varied than the 220’s.
4. AmberPRO Personal Cloud Storage + AC2600 Router
A dual 2TB RAID 1 vault that also replaces your Wi-Fi router.
This is the most ambitious pick on the list because it is two devices in one. The AmberPRO packs 2TB of storage (two 2TB drives in RAID 1 for data protection) and a built-in AC2600 Wi-Fi router with 4×4 MIMO (four antennas for faster, more reliable connections) and beamforming (which focuses the signal toward your devices), so one compact box can handle both your home network and your backups. An HDMI output means you can plug it into a TV, and Docker support opens the door to apps like Plex and Home Assistant.
The expansion options are generous for a unit this size. Two USB 3.0 ports (one Type-A, one Type-C) let you attach extra storage, while one Gigabit Ethernet WAN port and two LAN ports keep wired devices connected. The 2600 Mbps data transfer rate is the headline spec, and the promise of a single box replacing a router and multiple external drives is genuinely appealing.
The reality is rougher. Owners describe a convoluted setup with conflicting instructions and two admin pages that rarely match, and one reviewer found the unit failed after less than three years, calling the backup software unreliable. Support from LatticeWork drew complaints for being unresponsive even under warranty. The idea is smart, but the execution demands patience and technical comfort.
All-in-one appeal: No other pick combines a full router, two drive bays, and an HDMI port in one compact chassis.
Setup reality: This is for tinkerers who enjoy configuration; anyone wanting plug-and-play should look at the Buffalo units instead.
Choose it for: a small apartment where one device can cover routing, storage, and media streaming.
Avoid it for: a stress-free first NAS experience — the configuration demands are real.
Understanding the Specs
RAID 1 vs RAID 0
RAID (Redundant Array of Independent Disks) is a way to combine multiple drives. RAID 1 writes the same data to two drives, so you get an automatic backup — if one drive dies, your files survive on the other. RAID 0 combines drives for full capacity but offers zero protection. For a 2TB NAS, RAID 1 means you pay for 4TB of drives but get 2TB of safe, mirrored storage.
Transfer Speed (MB/s)
Megabytes per second (MB/s) tells you how fast files move between your computer and the NAS. At 17-24 MB/s, a large video backup takes a while but finishes overnight. Newer models with faster processors can hit rates several times higher, which makes a real difference when you move many gigabytes of photos or footage regularly.
