Oh Apple, you sly devil, what with all the secretly upgrading hardware
and not even telling us. Thanks to eagle-eyed reader Eric Wortman, we now also found that the Mac Pro gained a RAID card option for those who need mounds of storage and a secure, redundant system with which to manage it. The card supports RAID 0, 1, 5, 0+1, and Enhanced JBOD. The card also features a 256MB cache and a 72 hour battery with which to protect that cache, and it occupies the top PCI Express card slot, connecting to all four internet drive bays.
What's all this RAID connectivity going to cost you? A cool $999 on top of the price of your Mac Pro.
