Summary: It's a one terabyte drive, what more can you say about it? I tried to mirror this drive from an identical Seagate ST21000428AS but windows won't let me do it, saying there isn't enough room. I guess I should have bought the second drive slightly larger.
Summary: Bought this in May and now it is dead in November. I bought it because it was identical to my factory original. Worked fine until the last few days when i noticed a slight noise when it was running. Two hard drive failures in six months is hard to take.
