Have an iMac 2011 and didn't have an ssd installed, i can get this done for about £100 quid but it then voids my warranty. So i've thought bout getting one of the seagate thunderbolt enclosures as theoretically it should give the same boot time/response as if it was internal. (anyone disagree?) My question is, whether its worth paying another £70!! just to have this version on my desktop, i can see myself using thunderbolt in the future so it would future proof myself for further TB devices. http://store.apple.com/uk/product/H...x-thunderbolt-adapter-for-desktop-hard-drives or i can go with the "cheap" version for £100 and not be future proof, thoughts?
