Pros: Very solid.

Cons: none that I have noticed at this time

Overall Review: I have it hooked up to an external 500gb hard drive and it appears to work just fine hard drive ran for over 3 hours while copying files from my old hard drive with no problems.

Pros: Quick, quite, plenty of storage

Cons: Only shows as 430gb but see other thoughts

Overall Review: Drive has 70gb set as a hidden partition that I can't do anything with, however this may have more to do with my copying program than the drive

Pros: Made changing out my laptop's hard drive from 80gb to 500gb a snap. I wouldn't think of trying to do it with out this now.

Cons: Should come standard with the dual connector

Overall Review: I purchased the dual connector to be safe, they should consider bundling the two products since most people will be going to a hd on the larger end.
