I needed extra help with installing this backup on my mac laptop. WD tech support was extremely helpful and the follow up was not expected but most appreciated. I have bought WD backups before and was always pleased. I was installing on an older OS and WD walked me through it. It is running great. We buy at NewEgg because they are reputable too.
I'm not into the third generation of Buffalo DriveStations. I use them in fours for backups; two alternating and two alternating off-site. I alternate two on-site so that if there's a drive failure, I'll still have a relatively recent backup. That has never happened with DriveStations. I've bought new DriveStations because, when I get a new computer, it inevitably has a larger disk. The Axis Velocity drives are nearly silent (you can hear disk seeks sometimes) and take full advantage of USB 3.0. With the two drives I just bought, I backed up 257 GB in less than 90 minutes per drive, using AES encryption, which slowed the process.
Easy plug and play
