Summary: I wrote an earlier review lambasting the drive for not having the stated 750 GB's, however, after further research I learned that HD manufacturers determine capacity different then the way Windows Explorer calculates it. Thus resulting in the difference.!
Summary: I used this to test system imaging software by first saving the images from Lenovo laptops and then restoring them to this drive. It worked fine and is currently holding a working backup for my primary laptop.
Summary: It's fast and quiet in my laptop. How long it will last is anybody's guess, but so far I've had very good luck with these HDs. I have them in several laptops where they get used all day, every day, and have not had one fail. Yet.
Summary: I'm only rating on use quality because I haven't had it long enough to judge failure rate. However, before buying I did a little research and found Hitachi drives have a lot of good marks from actual users. I wanted to replace a smaller SSD with this so I could use the SSD on a different netbook. Once I got it all running, the speed was only slightly slower (barely even noticeable) than the SSD it replaced. I love it!
