Pros: I've been through dozens of laptop hard drives, and this is by far the fastest. Very quiet to boot. Check the net for benchmarks, you will have a hard time finding a faster laptop hard drive.

Cons: Always would like more space.

Overall Review: Contrary to other reviews, this drive is compatible with Core 2 Duos and Windows XP. Most likely the other reviewer had motherboard/controller issues. I've used it with XP, Vista, and Mac OS for many months with zero problems.
