Pros: I bought this drive to replace the aging Fujitsu 4gig 4200rpm drive that came in my Dell Inspiron 3500 laptop. This drive put new life into that old laptop! The screaming bearings from the Fujitsu are a thing of the past. In fact, this drive is so quiet that I can only hear it when working in the small hours of the morning when everyone else is asleep! Installed very easily (just make sure you pull the adapter off the old drive first) and took all the software quickly and easily. The 5400rpm with 8mb cache is noticeably faster, too! The machine now boots in less than 90 seconds, where it used to take a little over 3 minutes. Newegg's shipping was very prompt, too!

Cons: Ummmmm ... it won't make my processor run faster? Otherwise, I can't think of any!
