"Ideal for video and creative professionals with demanding storage needs as well as for tower server applications, this hardware RAID option supports RAID levels 0, 1, 5, 0+1, and Enhanced JBOD. It has 256MB of cache and an integrated 72-hour battery for protecting the RAID cache. The card occupies the top PCI Express slot (slot 4) and connects to the four internal drive bays. To enable your Mac Pro for hardware RAID, select the Mac Pro RAID card option and two or more hard drives in bays 1 through 4. Each RAID level has minimum requirements for the number of hard drives"
