ultra-small, super-fast external hard drive which is also very good work with my iMac. I bought this hard drive, on the one hand data from the iMac to be transferred to a Windows notebook and on the other hand to carry out an ongoing backup of my iMacs. To this end, I created just 2 partitions, which worked easily. When I again need a hard drive, I'll just get myself this drive again. 100% buy recommendation.
