I've got a 2011 Mini coming and i want add an SSD and keep the original HDD in place. I believe you can add a 2nd disk with a kit, is this possible to buy in the UK? Can anyone also recommend a cheap SSD that will work, it only needs to be small like 60GB or something just to run software then i'll use secondary disk for media. If i was to upgrade the HDD can i put anything in there? or do only specific disks work with macs?
