Just submitted this feedback to Apple: " I just lost my System drive in my MP3,1. I had Fusion drive made from 128GB OWC ssd and 1TB hdd. Ssd died. First thing that comes to mind is, can I recover the data I was working after last timeMachine backup? Since ssd's are usually small and hdd's can be very big, wouldn't it be nice, if you could have a version of Fusion drive, where ssd's content is duplicated also to hdd? And you could boot from hdd only, if ssd dies? System would be slow, but you could keep working and at least easily copy data to new Fusion drive. " Good idea? Any thoughts?
