WD drives do not have a high fail rate. Got myself a WD 3TB mybook, USB3 and it is quite awesome (aside from the noise and lengthy spinup time) but transfer rate is around 150MB/s (yes that's megabytes, not megabits) which is very acceptable for a spin drive.
See you in about Six months. While you about it, take the time too look at the forums here.
See how many times the same problems are duplicated.
There are about three symptoms that always crop up.
I must be lucky then as my 2 WD drives (Caviar SE 160GB from 2005 and a My Book Essentials 500GB drive from 2008) have have been working just fine (or WD sucked after that point.)
In all honesty though, You can go to any forum beyond tom's hardware and you'll find each place a bit different. Some forum, you'll see more seagate drive issues, others could be toshiba's, ect. Then there are other forums that you find a nice mix of different company drives that have issues.
Basically, all i'm saying is, a single forum isn't the best way to judge a hardware failure rate and even then, even multiple forums isn't the best place to judge. (Although multiple forums make it at least a little better in figuring it out.)
Have to find those statistics that actually show how an company overall is doing.
Just sent my 1 year old WD essential 2TB back to dealer, broken. They have the new ones in store now so i will get either money back or this new one. Hope it will be more reliable. I lost 2TB of data with it, dueto ecryption it cant be rescued.
