I needed a new external hard drive for my iMac. I'm running Lion 10.7.3. I was in Best Buy and they had a LaCie minims 2TB, usb 3.0 on clearance for $113. I picked it up but before I open it, I wanted to ask opinions. Is this going to be compatible with my iMac (newest model) and is it a good choice? Do you have better recommendations? Thanks so much.
