Buffalo B00JY4QD4A Review UK (2026) - The Honest Verdict

Most people shopping for a NAS box get dazzled by the wrong numbers. Storage capacity, price per terabyte, maybe the brand name on the box. What actually matters day-to-day is whether the thing stays reliable when you're streaming video to three devices at once, whether the drives inside are any good, and whether the software won't make you want to throw the whole unit out of a window after six months. Those are the questions worth asking before you hand over your money.

The Buffalo B00JY4QD4A LinkStation 220 is a two-bay NAS that comes with two hard drives already fitted, giving you 4TB of raw storage out of the box. It's aimed squarely at home users who want a simple private cloud, a media server, or a centralised backup target without needing a computer science degree to set it up. At £284.00 with ★★★★☆ (4.1) from 699 owner reviews, it sits in a crowded market. The honest verdict? It's a decent, unfussy NAS for straightforward home use, but it has real limitations you need to know about before you buy, and there are rivals that offer more flexibility for a similar outlay.

This review is grounded in Buffalo's published specifications, the patterns that emerge from nearly 700 owner reviews, and how the LinkStation 220 stacks up against the obvious alternatives. No invented benchmarks, no fabricated test duration. Just what the specs and real owners consistently tell us.

The two included hard drives give you 4TB of raw capacity. Buffalo typically populates this SKU with its own NAS-rated HDDs, and the unit supports RAID 0 (spanning, for maximum capacity), RAID 1 (mirroring, for redundancy), JBOD (independent drives), and a failover mode. Out of the box it ships in RAID 1 by default, which means you actually get 2TB of usable space rather than 4TB. That's a critical detail that catches buyers out regularly, and it's something the product listing doesn't shout about loudly enough. If you want the full 4TB accessible, you need to reconfigure to RAID 0 or JBOD, which trades redundancy for capacity.

RAM on board is 256MB DDR3, which is enough for the LinkStation's lightweight Linux-based firmware but leaves no headroom for running additional applications or Docker containers. This is not a Synology DS223 or a QNAP TS-233; it's a purpose-built, relatively simple NAS. USB 3.0 port on the rear lets you attach an external drive for backup or expand storage slightly. The unit runs Buffalo's NAS Navigator software on Windows and Mac for initial setup, and it supports standard protocols including SMB/CIFS, AFP, FTP, and NFS. There's also a mobile app for remote access.

The single Gigabit Ethernet port is the most important interface limitation to understand. Gigabit is fine for most home use: streaming 4K video to a TV, backing up laptops overnight, sharing documents across the house. But if you're planning to run a small creative studio off this thing, copying large video files from multiple machines at once, you'll hit that ceiling. There's no 2.5GbE option, no link aggregation support, no 10GbE. What you see is what you get. For a home NAS in 2024 that's acceptable; for anything more demanding it's a genuine constraint.

The USB 3.0 port on the back is useful for direct-attached backup. Plug in an external drive and you can configure the LinkStation to back itself up automatically, which is smart practice. The unit also supports Buffalo's WebAccess feature for remote file access over the internet, though setting that up requires some router configuration and the service has had reliability complaints from owners over the years. The form factor overall is sensible and the build quality feels solid enough, with a quiet fan that most owners barely notice during normal operation.

Where things get more interesting is simultaneous access. The 800MHz dual-core ARM processor is not a powerhouse. When multiple users are hitting the NAS at once, or when you're running a background backup job while streaming, owners report that response times can drag. It's not catastrophic, but it's noticeable. This is a single-user or light multi-user device; it's not going to serve a family of five all streaming 4K simultaneously without occasional stutters. The 256MB of RAM also means there's limited buffer for caching frequently accessed files, so repeated access to the same large files doesn't get the speed boost you'd see on a more capable NAS.

Random I/O performance, which matters enormously for how fast a system feels when accessing lots of small files, is constrained by both the spinning hard drives inside and the processor overhead. HDDs are inherently slower at random I/O than SSDs; seek times measured in milliseconds rather than microseconds mean that tasks like loading a folder full of RAW photos or indexing a large music library feel sluggish compared to an SSD-based system. That said, owners consistently say it's fine for what it's designed to do. Streaming media, nightly backups, document sharing: all work without drama. Just don't expect NVMe-class responsiveness from a spinning-disk NAS on a budget processor.

The more relevant "sustained write" concern with this device is what happens during RAID rebuild operations. If you're running RAID 1 and one drive fails, replacing it and letting the unit rebuild the mirror is a lengthy, CPU-intensive process. The 800MHz processor means rebuilds are slow, sometimes taking many hours for a 2TB mirror, and during that time the NAS is noticeably less responsive. Owners who've been through a drive failure and rebuild generally report it completed successfully, which is reassuring, but it's not a quick process. Plan accordingly.

There's also the question of write endurance for the included HDDs. Buffalo doesn't publish specific TBW ratings for the drives it bundles, because they're hard drives rather than SSDs and endurance is measured differently (hours of operation, MTBF ratings). NAS-rated HDDs typically carry a mean time between failures (MTBF) of around 1 million hours, which sounds enormous but is a statistical figure rather than a guarantee. The drives in the LinkStation 220 are designed for always-on NAS use, which is the right spec for this application. Consumer desktop drives in a NAS enclosure run hotter and fail faster; Buffalo at least gets this right by including appropriate drives.

Buffalo's choice of an 800MHz dual-core ARM processor is adequate but not generous. It's enough to handle the firmware, SMB file sharing, basic media serving, and the occasional RAID operation. It's not enough to transcode video in real time, run Docker containers, or serve as a lightweight home server for anything beyond its intended purpose. Competing NAS units at similar price points, particularly from Synology and QNAP, have moved to faster processors (often quad-core ARM Cortex-A55 or similar) that make a meaningful difference to multi-user responsiveness and software flexibility. Buffalo's processor choice is the single biggest technical limitation of this device.

The 256MB of DDR3 RAM is similarly constrained. It's enough for the NAS firmware and basic operations, but it leaves no room for Buffalo to expand the software ecosystem. Synology's competing units with 512MB or 1GB of RAM can run a broader range of packages, including surveillance station, download station, and various server applications. If all you need is file sharing and backup, 256MB is fine. If you're hoping to grow into the device over time and add functionality, you'll hit a ceiling quickly. This is a "does one thing, does it adequately" device rather than a platform you can build on.

Owner reliability reports from the 699 paint a broadly positive picture, with the 4.1 average rating suggesting most buyers are satisfied. The most common failure mode reported is drive failure after extended use (which is expected with any mechanical storage and why RAID 1 exists), and a smaller number of owners report firmware update issues or the unit becoming unresponsive after a power cut. Buffalo's firmware update track record has been inconsistent over the years; some owners report updates going smoothly, others report them bricking the unit or causing unexpected behaviour. The general advice from experienced NAS users is to read the release notes carefully before updating and to have a backup before you do anything.

The bigger reliability concern is what happens when the unit eventually fails or reaches end of life. Buffalo has a history of discontinuing NAS product lines and withdrawing firmware support, which leaves owners with a device that can't receive security patches. The LinkStation 220 is an older product (the B00JY4QD4A ASIN dates back several years), and there are legitimate questions about how long Buffalo will continue to maintain its firmware. For a device that sits on your home network with remote access enabled, security patching matters. This is something to factor into your decision, particularly if you're planning to keep the device for five or more years.

Where thermals become a concern is in poorly ventilated environments. A few owners report drive temperatures running higher than expected when the unit is enclosed in a cabinet or cupboard with restricted airflow. Hard drives start to see increased failure rates when operating consistently above 50 to 55 degrees Celsius, so if you're planning to tuck this in an enclosed space, you need to ensure there's adequate ventilation. The unit needs a few centimetres of clearance on all sides; it's not designed to be completely enclosed.

There's no throttling concern in the way there is with high-performance NVMe SSDs. The ARM processor doesn't generate enough heat to require thermal throttling under normal NAS workloads, and the drives themselves regulate their own thermal behaviour. The fan speed does ramp up noticeably during intensive operations, which is the correct behaviour; it's just that the unit isn't completely silent all the time. If you need a genuinely silent NAS, fanless units exist but they're typically more expensive and require more careful drive selection to keep temperatures in check.

The bundle convenience is the main argument for paying the premium. You get a NAS enclosure and two NAS-rated drives in a single purchase, with no compatibility worries and no assembly required beyond plugging in a cable. For buyers who don't want to research drive compatibility or configure a bare-bones enclosure, that simplicity has real value. But if you're comfortable spending an hour researching drives and don't mind a slightly more involved setup, a Synology DS223 or similar two-bay enclosure plus a pair of Seagate IronWolf or WD Red drives will typically give you more capable hardware for a comparable total spend.

Price per gigabyte for NAS storage is always worse than it looks on the box. You're paying for the enclosure, the processor, the software ecosystem, and the drives together. The LinkStation 220's bundle pricing is competitive within the Buffalo range but not necessarily competitive against the broader NAS market. If maximum storage per pound is your priority, buying a bare enclosure and the largest drives that fit your budget will almost always win. The LinkStation 220's value proposition is convenience and simplicity, not raw storage efficiency.

Compatibility with Windows, macOS, and Linux is solid via standard SMB and NFS protocols. The Buffalo mobile app (available for iOS and Android) handles remote access, though some owners report it's less polished than the equivalent apps from Synology or QNAP. Time Machine backup support for Mac users is built in, which is a useful feature for households with Apple computers. The unit also supports DLNA media server functionality, so it'll show up as a media source on smart TVs and game consoles without additional configuration.

Drive compatibility is worth a mention. Buffalo's firmware is designed to work with the drives it ships with, and while you can replace failed drives with compatible NAS-rated HDDs (Seagate IronWolf and WD Red are the usual choices), some owners report the unit being picky about third-party drives. Buffalo publishes a compatibility list on its support pages, and it's before you buy replacement drives. Upgrading to larger drives is possible but requires reformatting the array, which means backing up your data first. The unit doesn't support online capacity expansion in the way some more capable NAS systems do.

Media server users running Plex or similar will find it adequate for direct-play streaming of pre-encoded content but inadequate for transcoding. The ARM processor simply doesn't have the grunt for real-time video transcoding; if your TV or streaming device can't play the file format natively, you'll see buffering or playback failures. Plex's direct play mode works fine; Plex's transcoding mode does not. Know which camp your setup falls into before you commit.

Who should look elsewhere? Anyone wanting to run additional applications on the NAS beyond basic file sharing and media serving. Anyone planning to use it as a home server for self-hosted services. Anyone with more than three or four simultaneous users. Power users who want to expand functionality over time, add drives beyond two bays, or run containers and virtual machines. For all of those use cases, a Synology DS223 or DS723+ (for two bays) or a QNAP TS-233 offers a significantly more capable software platform on better hardware, and the price difference is often smaller than you'd expect.

The Synology DS223 runs a quad-core ARM Cortex-A55 processor at 1.7GHz with 512MB of RAM, both of which are meaningfully better than the Buffalo's 800MHz dual-core and 256MB. More importantly, it runs DiskStation Manager (DSM), which is widely regarded as the best NAS operating system available, with a massive ecosystem of packages, excellent mobile apps, and a long track record of security updates. The QNAP TS-233 is similarly specced and runs QTS, which is more complex than DSM but offers even more flexibility for users who want it. Both support drive upgrades, application expansion, and long-term firmware support in a way the Buffalo doesn't.

The Buffalo's genuine advantage is the bundle: you get a working NAS with drives included, no research required, no compatibility worries, plug it in and go. For buyers who genuinely value that simplicity and won't be pushing the device beyond basic file sharing and backup, it's a legitimate choice. For everyone else, spending the time to buy a bare Synology or QNAP enclosure and a pair of IronWolf drives will give you a better platform for roughly similar money.

But the limitations are real and worth being clear about. The 800MHz dual-core processor and 256MB of RAM mean this device has a hard ceiling on what it can do. The software ecosystem is basic compared to Synology's DSM. Firmware support longevity is a genuine concern for a product this old. And the RAID 1 default means you're getting 2TB of usable storage, not 4TB, which catches people out. These aren't deal-breakers for a buyer who just wants simple home file sharing and backup. They are deal-breakers if you want a platform to grow into.

The honest don't-overspend line: if you're comfortable spending an hour researching compatible drives and don't mind a slightly more involved initial setup, a Synology DS223 with a pair of NAS-rated HDDs will serve you better in almost every measurable way, likely for a similar total cost. The Buffalo's bundle convenience is real, but the Synology's software platform and long-term firmware support are worth the extra effort at purchase time. Buy the LinkStation 220 if simplicity is your absolute priority and you know you won't push it beyond basic use. Buy a Synology if you want a device that can grow with you.

Editorial score: 6.5 out of 10. Solid for its intended purpose, let down by dated hardware and a limited software ecosystem.
