I put this in a Old (2007)

OK what would you like to hear? This HD works & spin's like it is suppose to; Spin is 5400 RPM, some people complain about the slower rate of data transfer compared to a 3.5 HD that spins at 7200 RPM; Not that noticeable to me.

Nada

It was the drive i needed for my Asus X401 however it came DOA. After 3 days working on the drive I had no success. Had to contact WD website. Now I am just waiting for the exchange. Will change the rating depending on how it comes back to me.

excellent drive for the price. been running for about 6 months now with no issues.

I was looking to purchase a bunch of HD's for my stock. These fit the cost I was looking to pay. So far, no issues with any of the drives.

Great item, will buy again, no problems at all, recommended to everyone A+++++++
