Hey guys, not to thread-jack, but how do you go about upgrading a hard drive on a Mac? My brother's got several devices I can use to convert SATA to USB, but being strictly a Windows guy, he's got no advise for me about how to clone a hard drive. How would you do it?

Also, would you recommend one of those hybrid drives? I've got a Macbook 4.1 running Snow Leopard and I'm wondering if it will offer any significant performance or efficiency upgrade over my stock Hitachi 120 GB drive.

Thanks!
