Hi, new member here (been lurking a lot though) with my first question. I have a new late 2012 Mac mini i5 and I fitted a OCZ Agility 3 120 Gb SSD, using the OWC fitting kit. The factory fitted 500Gb HDD was attached to disk0 sata connector & the SSD to disk1 sata connector. When I used diskutil to create a fusion drive I chose /dev/disk0 /dev/disk1, which, I think means the fusion is using the HDD (disk0) as the o/s install disk and not the faster SSD. Am I right in thinking this??? Should I do it again in diskutil but as /dev/disk1 & /dev/disk0 ??? Sorry for the long winded question but I want to get it right. regards all.
