Looks like Hitachi would be the best choice, they are more or less the cheapest on my list too...
Both drives of WD i have are elements, both failed, but i was able (after 9 hours each) to get all my info back and restore to another drive.
WD Told me that its my fault i break them (i agree kinda)... They said that each time you need to make sure you "safely remove hardware" and not just rip out the usb like i do. Always make sure you boot the drive down before ripping out the power adaptor.
In short WD said, if the blue light is on, its not safe to turn off...
I have been using my maxtor in my usual careless manour, and had no issues at all. So all i can conclude is, the WD is fine unless your careless like me.
I have had a few friends having bad WD drives too, but again, then always do what i do and unplug the usbs with a further thought to eject or power down.
