I'm struggling to make a decision on a thunderbolt drive. It's going to hold sound banks and sample libraries for music production so a standard USB drive wont cut it. I want a drive with 7200rpm, thunderbolt with possible backwards compatibility with older machines (USB3?) ... I've been recommended to get an enclosure and add the drive myself? And also suggested a 3.5 7200rpm drive instead of 2.5 7200rpm as the 3.5 is faster (i thought it 7200rpm was 7200rpm regardless of form factor) So taking all that into account i can't seem to find a drive that will fit my needs, can, i'd love to hear some recommendations and places to buy them in the UK. So either a thunderbolt 1TB unit or a thunderbolt enclosure and a 1TB drive to suit.
