hi all. I have a 2008 Mac Pro with 32GB of ram, four 2tb drives. I'm a musician so all PCI slots are taken: two UAD audio processor cards and a FireWire PCI because the native FireWire ports stopped working a couple of years ago (I need this because my audio interface uses FireWire ). It seems like the last thing I can do to get even better performance is to add a ssd drive and of course I'd like to use one that would replace my main drive which has all my software and virtual instruments. Samsung makes a 2tb evo for around $600. My question is, are ther any limitations to using such a drive? Can I connect it to the second optical drive on that machine? Will the improvement in speed be significant if the drive is about 80% full? I'm on Yosmite btw. And I can lose one of the Sata drives if it's a better way to connect the ssd. Alternatively is this silly? Should I just find a faster 2012 12 core and have a more recent machine to work with? Would it be just as fast as my 3.1 with an ssd? Thanks in advance for your input. Cheers.
