Western Digital's My Book series has been around for some generations now, catering to users who want huge capacity but are not necessarily looking at portable drives. With the My Book 4TB drive WD offers a desktop drive with the maximum capacity available on a single drive.

It worked fine for about 2 years, but almost exactly on the 2 year anniversary of the date that I bought it, my computer wouldn't recognize it, saying that the drive had malfunctioned. This is my 4th WD hard drive to fail. Stay far, far away from this.

So far so good, if it is as reliable as other WD drives we have in service, will be great

A good buy, but it is a 3400 rpm drive, not 7200. I should have perused the specs more carefully. Basically only good for storage of data. Not suitable for editing video as I had planned.

The second my book that I have installed and it works as well as the first one. Good value and great transfer speed. Will buy another as needed

Strangely mixed reviews. Editors of The Wirecutter award the My Book their "Best External Desktop Hard Drive" title partly because of its good record for reliability. In their analysis of Amazon.com reviews, they found a failure rate of under 5 percent.

Lots of capacity for the price; Fast transfer speeds; Easy setup

Mixed reviews for reliability; Some software glitches

Right away it's clear to see where the name of the product comes from - it looks like a book! The front of the My Book has two clear rings. The inner ring is lit with a blue LED to show the remaining free space on the drive.

First time using a WD hard drive, currently doing brilliantly. Price is very good on Play-Asia.

THIS IS ONE BAD ASS STORAGE DEVICE!!!

Why is this external hard drive different from all other external hard drives?
