What customers say about "Key Specs"
Buffalo LinkStation 220 8TB NAS for Home/Office
  • Capable of holding lots of storage, which is pretty cool.
  • The price was so cheap that I wondered if it had the drives in it. YES, the two 4 TB drives were installed. It is really plug and play.
  • This is my 2nd LS 220 and it works great for my archives and other services. I love the availability to select HD's to install up to 8 Tb. I recommend for ease of install. I'm planning on a third soon.
  • The unit is designed to stand vertically, and the slots for cooling are at the top. This doesn't work well for a dusty environment. It would be better if the slots were on the side.
  • Performance isn't great - roughly 40 MB/sec with SMB over gigabit (FTP will nearly saturate gigabit)
Buffalo LinkStation 420 (LS420D0602) 6 TB 2-Drive NAS for Home/Home Office
  • I am using this as another level of storage for our devices and mainly for pictures. We have about a million pics
  • Capable of holding lots of storage, which is pretty cool.
  • Easy little 2 bay personal data storage for home network. You do not need to install the included programs just map the network drive as normal.
  • Bought mainly to store backups - but now finding more uses than just for storage.
  • Transfer rate is pretty damn slow at 10-12 MB/s tops, and much less over wifi for some reason. So beware that if you intend to back up a few TB to this you will need a couple of days.
  • This NAS is very slow, so it's not worth it, for what I'm using it right now (as a suivellance camera recording) it does the job.

What customers say about "Features"
Buffalo LinkStation 220 8TB NAS for Home/Office
  • Good set of folder-specific options to play with (DLNA, FTP and WebAccess)
  • Email alerts are informative and work very well
  • Supports both local and AD user accounts
  • Works well with Seagate NAS disks
  • Comes with only US power adapter, no option to switch the plug head to any international standard. (major drawback)
  • Bright white leds in front make it a hassle to keep on your desktop.
  • No cloud backup
Buffalo LinkStation 420 (LS420D0602) 6 TB 2-Drive NAS for Home/Home Office
  • Easy to install and now doing a great job of backing up my files. The whole family are now using it as their file transfer and backup device.
  • The product itself suits my needs well - I am using it as a basic file server for the three PCs on my network and as an occasional media server. Speed is fine for this purpose and set-up was easy.
  • Really easy set up and easy to use apart from the remote access apps which are clunky by design and not reliable.
  • Noisier than I had expected and took 37 hours to Raid a 4TB setup. So be prepared for a couple of days to set it up properly.
  • Bad. Initially wouldn't show up in NAS navigator (unlike my existing Linkstation which shows up every time), and when it did, it stated that it couldn't return drive info.

What customers say about "Interfaces"
Buffalo LinkStation 220 8TB NAS for Home/Office
  • Connects to APC UPS units via USB to shut down the unit before the battery is exhausted
  • USB 3.0 and the USB auto-copy is a nice feature.
  • Ability to automatically backup any devices plugged in to USB
  • Make sure to hook it up to a 1GB ethernet port for full performance.
  • There is a wonderful USB 3 port and one would think the touted ability to use a USB drive is limited to Buffalo drives only.
Buffalo LinkStation 420 (LS420D0602) 6 TB 2-Drive NAS for Home/Home Office
  • USB direct copy feature is particularly useful as do not have to turn any computers on to copy stuff onto NAS box.
  • I bought it for copying my movies, pictures and songs from an USB drive, and keep it secure for the future in raid 1 mode.
  • Works very well for what I use it for. Mainly streaming movies throughout my house and data backup. Make sure to hook it up to a 1GB ethernet port for full performance.
  • The rear has a power connection, a port for the RJ-45 connection to the network, and a USB port that allows you to plug in another hard drive, which can be shared on the network or used to backup the Buffalo.
  • The Link Station 420's outer case is entirely made of plastic. On the back there is a single USB 2.0 port, which confuses me, since this is a new device. Why not USB 3.0?
