Experience: 34 Months
Worked flawlessly after cloning the faulty drive to it.
Nove so far.
Not the best drive around but the best price/performance at the time of purchase. It was used to replace a failing 250go drive and it went smoothy.

Experience: 1 Months
 Verified Owner
Works, fast rpm, cheap
The HDD died in my HTPC, this was the perfect replacement for it.

Experience: 5 Months
 Verified Owner
Great Price
None sofar
Purchased these for customers laptops as replacements for dead drives. Great value for the money, and on sale they are the same price as 5400rpm drives, which doesn't hurt.

Experience: 3 Months
 Verified Owner
Fast, quiet, reliable so far
None to mention considering it's a mechanical drive
My ThinkPad X220 came with one of these preinstalled, and that's been reliable for a year and a half now, and I wanted to get something for a USB 3.0 enclosure - this drive was a great fit - there's really no disadvantages with the 7200rpm spindle speed compared to the 5400rpm drives, but you get a much quicker drive.

Comment: Not the largest capacity, but solid performance makes this an ideal upgrade disk for an aging laptop disk that's filled to capacity.
