I built my filer about a year ago so drives were a little more expensive, but I spent a little over $2000 overall to go with hardware RAID6 on 12 drives. If you get one of the areca PCIe x8 controllers you should be able to pull 800mb/s+ off the disks. The areca 1231-ML ($650) says it does Performance: (Sustained Rate / All-in-Cache) RAID 0: Read - 885 / 1624 MB/s; Write - 847 / 1295 MB/s RAID 5: Read - 846 / 1624 MB/s; Write - 816 / 1295 MB/s RAID 6: Read - 811 / 1624 MB/s; Write - 776 / 1295 MB/s
Based on real benchmarks I have seen these are pretty real numbers. The card can have a cache of up to 4gb and modules aren't too expensive. The other benefits to a card like the 1231 is that it has an integrated NIC and management software so you really can go barebones on the OS and be able to use the full functionality of the card. A friend of mine went with one of these non-hardware raid cards ( http://www.newegg.com/Product/Product.aspx?Item=N82E16815121009) and is using OpenSolaris/ZFS with it and has been pretty happy. I can't really give performance numbers because he used the PCI-X card in a standard PCI slot, but it was nowhere near the areca.
