Hitachi Deskstar 7K500 In Depth review
 

Hitachi's Deskstar series of drives have always been rather polarizing here at StorageReview as well as around the enthusiast community in general. One reason is sheer capacity and performance... Hitachi's (and formerly IBM's) drives have always been among the largest and speediest around. Another cause, however, is a legacy of troubles. Two iterations, the 75GXP and 60GXP, have been dogged by allegations of high failure rates.

Deskstar failure rate remains high in my opinion; 4 drives in 3 years with the latest in May of this year.

I must point out that the replacement drive came back hell a lot faster now than say a year ago. This time it took 2 weeks from the day I shipped back the dead drive to receiving a new one versus 4-5 weeks.
