Pros: Installed this in my MacBook Pro 15" CoreDuo model (bought new in April 2006). Lots of space. Quiet and just as speedy as the 100gb drive it replaced.

Cons: Tedious installation, but that's not the drives fault. Google "macbook pro hard drive replace" and you'll get several sites to help guide you through the install.

Overall Review: Highly recommended for anyone that needs to add more storage to their MacBook Pro or MacBook (much easier installation).
