Travelstar Z5K320 is a 7mm, 5400 RPM 2.5-inch hard drive with capacities ranging from 160GB to 320GB. The 320GB per platter one-disk models are designed as a direct replacement for standard 9.5mm HDDs, for use in notebook PCs, external storage and gaming consoles. The Z5K320 also accommodates new thinner and more robust device designs. These models deliver best-of-breed acoustics for near silent operation.
This was a replacement drive for me. It installed without any problems and I was able to transfer all data from old drive to this drive without any issues.
Great Product at decent price4/22/2012
I purchased this hard drive as replacement for my laptop hard drive which died within 1 year. I received this product within 3 days of order. Put it in the laptop, load OS and my laptop was up and running. I found this hard drive much slimmer than the original one and also faster. I am very happy with the purchase.
