I'm converting my Mac Pro into a file server, and want to create a RAID 5 system with 1TB Seagate ES.2 Drives. I would like to use hardware RAID, but Apple's $700 price tag on even the older version of their controller is too much to swallow. I'm not too familiar with RAID controllers, and I don't know if my price range is reasonable, but I know that many of the newer controllers aren't compatible anyways. I would really appreciate any experience or advice with cards that might be a good solution. Thanks!
