4tb hard disk compatible with mac pro 2007 for mac#
Put the system on its own SATA II bus - the ODD port for one is great, put audio on a PCIe SSD controller and go for one or two SSD (RAID0 for max) and use an 8x slot you have (Sonnet Tempo Pro is the only one they have certified for Mac Pro 2006-7) and one or two 250 or 500GB ($270 or $500 the pair) SSDs. I don't know about Crucial but for me, I have half a dozen Samsungs. Only time you see real b enefit from 6G is scratch, Aperture and audio libraries, and that from PCIe SSD cards, but that also frees up drive bays not having to be used, the SSD fits on the controller, and moving high IO off t he slow limited native SATA II bus itself which has less than 800MB/sec of bandwidth to share. The Samsung EVO works fine, and on ANY Mac Pro until 2013 model, SATA II is fine for system. Best upgrade I made - and I have made dozens in terms of RAM, 10K Raptors and later, gpu three times.
