Hi. Got an old early '08 2.8 GHz 'Penryn' octocore MacPro with 10 gig RAM, nVidia 8800 series video card (which was an upgrade option purchased with it), and a 1 terabyte HD. I've added a 2'nd terabyte HD and a 1.5 terabyte HD in a couple of other drive bays. General home user. iPhoto library is very bloated; bit over 100 gig.s, I'd say. primary 1 terabyte HD is a bit over 90% full, but still some free space. OS is Mountain Lion. Runs pretty well, but occasional app. freezes, once in awhile need a cold boot, can be a little slow to get things done at times... Did a little online checking. Looks like I could in theory get a 240 gig SSD from OWC, somehow pair it up with the old 1.5 terabyte drive by using step-by-step instructions via Terminal per a MacWorld Article (which I know almost nothing about), use some sort of software (Migration Assistant? Carbon Copy Cloner?) to move things from the 1 terabyte drive to the new Fusion drive afterward, somehow set it has the boot drive, then good to go, faster boot ups & much faster general performance. But I might need some sort of adapter kit to make the SSD fit i the HD bay. Is that all accurate? Anything else I need? I'm not a skilled techie, so instructions need to by pretty basic for me. Thanks in advance, guys. Richard.
