I have a 2010 mac pro and I would like to get a SATA III SSD to boot from. I also have 2 3TB disks in raid 1 right now for my media library but since that is running out of room (Only 3 TB usable) I would like to get another 3TB disk and put them in raid 5 for 6TB of usable space as well as protection from 1 disk failure (Correct?). Ive been looking for a card but cant really find anything that will boot. Looking to spend around $300-$400 on a card + SSD. Any suggestions? Not extremely educated on the topic so any help is appreciated.
