Customer Reviews of HGST Travelstar Z7K320 HTS723232A7A364 320 GB 2.5" Internal Hard Drive - SATA - 7200 rpm - 16 MB Buffer
Needed to replace a failing drive in a couple year old laptop. At 7200 RPM this is just the ticket for a little performance boost, and the price was within two dollars of the 5400 RPM drives. No brainer!
Excellent product works great
This hard drive is working great. Booting up and transferring files are very quick. I should recommend to friends.
