Hi Just taken delivery of my BTO 27" iMac and was wondering how to best connect my external SSD. Does any of you learned ladies or gents have any direct experience with hooking up an external SSD via USB 3 or USB C? I have a spare SSD that I wan't to connect but not sure of which external closure to buy. Also is it worth paying that little bit extra for a genuine Apple USB C cable or is a third party one good enough not to compromise transfer rates? Thanks in advance.
