See this thread on Hardforums: http://hardforum.com/showpost.php?p=1032222973&postcount=111 for more details. He's got a 1280ML and 24 disks with 22 in raid 6 and 2 hot spares, getting up to 588 MB/s sustained block read according to HDTach. Two other people on that forum (handles Ockie and odditory) have those cards, and are similarly impressed, but I don't see benchmarks from them. In any case, I agree with your suggestion: get two 12-port cards, or three 8-port cards, and save money and get better performance anyways.
