I'm looking to upgrade my 250GB HDD in my MacBook to something bigger. My external hard drive I was using is out of state (long story), plus I'd like a larger backup drive. Any suggestions as to brand? I like the flex series of Seagate so that in the future I can get a Thunderbolt connection if needed. Of course, price will be an issue too, but I'm just looking for suggestions. If I do decide to "make" my own with an HDD and enclosure, a suggestion on an enclosure would be great. I want something inexpensive but that looks nice and could possibly use Thunderbolt, FW, and/or USB.
