and one last question: do I only need 32gb or should I get 64gb?
as of now i'm looking at the Imation 32gb
$99 and the Imation 64gb
you can fit a lot more onto a 64gb drive, but I checked and without my dvd collection I only use 21gb for OS7 and a bunch of cache crap. also I've heard that ssd's power efficiency is reduced when you are doing large file reads, so I probably would just plug in the old drive into a usb port via enclosure to watch movies.
so, should I consider a 32gb drive as a possibility?
