    It just works great.

    I didn't time how speedy it is, or measure how quiet it was. I just needed another removable drive and this one works great. No problems. No noise. There are faster drives out there for money, but for home use, or backups, this is fine.

    It works!

    I bought this to replace the hard drive that failed in a Dell Latitude e6520 laptop. It was easy to replace and works perfectly.

    Excellent drive for the price

    Amazed with the speed. I backed my 3.5" system drive to this one and rebooted my system. It performed as well as the original 3.5" HDD that came with the desktop. I have bought 11 of those drives for various backups of my computers and I am very pleased. TK
