Summary: I own 6 of these, all internal drives and four of them in a WHS, the other two in an office desktop. I've had two and as of this week, three replaced through WD RMA process. They never run hotter than 37 degrees C but still they start having data inconsistencies or damaged sectors after 1 to 2 years...
Pros: Quiet, cool, lot's of storage space and when I bought, cheap! (before the flooding in Thailand)
Summary: Purchased this drive about an year ago and it failed on me. Windows would stop recognizing it, I scanned the drive and it detected bad sectors. Have sinced RMA'd it and WD sent me a new one. I used to be a big supporter of WD hard drives. Now not so much.
Summary: Couldn't find much info on this hard-drive. Finally after receiving the drive it stated plainly on the drive that it was a 16mg/cache, not 32. Returned the item and ended up buying a 32mb cache seagate 1TB drive for a few dollars more.
Summary: 1.5TB is really less than 1.5tb, in actual usable space. Still, this drive works, despite falling from dinner table height to a plush medium shag carpet. The warranty and company are rock solid. Can't go wrong there.
