Pros: Quiet & Fast Drive that works well with Macbook. First drive received was DOA, but NewEgg replaced relatively fast and paid for return shipping.

Cons: Not as fast as 7200rpm.

Pros: fast & quiet (when working)

Cons: 2nd drive attempt after DOA; Second drive stopped working after 2 weeks ownership - lost some data in process.

Overall Review: First drive received in Dec. 09 was DOA; NewEgg replaced and worked great for 2 weeks before giving out. I didn't want to try replacing again, so NewEgg graciously allowed for refund with paid return shipping and no restocking fee as this was the second defective drive sent. Thanks NewEgg! Going to try Hitachi once refund is complete.
