Doesn't work with PS3

Not sure why but it isn't compatible with my PS3, which was my main purpose of buying. Also, there is no on-off switch. It will be returned to the store.

WD Has always had reputable product. The price for the 4TB is perfect if you're looking to build up for your home media. Runs smooth, quite, and does NOT overheat. Great product!

Fast and Dependable

This huge-capacity storage device is particularly suited to archiving large media files like video, audio, and photo files, as well as backing up hard drives. File transfers are USB3.0 fast, as long as your computer and operating system are USB 3.0 compatible. One of these USB HDs survived a light bump; an equal bump disabled a USB drive by a different manufacturer, so I am quite pleased with the MyBook.

Exceeded my expectations

Excellent performance

Better Than The Rest

I have many external HDs, all of the big name brands, but this one is by far my favorite. It's fast, reliable, and holds a lot of "stuff" :) I currently have two of these, and am going out to get 3 more - they're that good!

Good drive so far

Software didn't install seamlessly on XP as advertised but did fine on Win7. No matter since I already have backup software and need the drive for secondary backup storage only. USB 3.0 makes a big speed difference compared to my older drives. I've already had 3 Ext HD failures in the past so will have to wait and see how long this one lasts.
