Pros: Installation was extremely easy (less than 5 min). Been running for about an hour now with no heating issues and the eSata connection to the laptop is infinitely better than USB 2.0.

Cons: None so far.

Overall Review: Used an old WD 250 GB Sata 1.5 HD from my desktop and vista recognized Immediately. Excellent buy for the price.

Comments: If you've everseen one of those giant copper bricks they use in dell systems, you would agree with me in that this is a huge upgrade. It runs smoothly, keeps my system in check.
