I am due to receive my new MBPr next week (2.3/8/256 version) and need a fast external HD to use for storage (mostly large Dslr raw files). These files will also be shared on my iMac (purchased late 2011, maxed out). I've considered using one of the new USB3.0 drives which would work fine for the MBPr but would be painfully slow on the iMac, which doesn't have USB 3.0. It looks like the Buffalo 1 TB Thunderbolt Ministation would solve my problem as it uses thunderbolt. It also has a USB 3.0 port included. eshop.macsales.com/item/Buffalo/HDPA1.0TU3/ Is this the best setup for me or is there another solution for portable storage that would be more versatile or cost effective? I see the great review below, but want to ensure I look at all options before pulling the trigger. FYI, I'm a middle aged Mac newbie. Lifelong Windows user. Really looking forward to my new MBPr!
