I was under the impression that the promise cards actually offloaded some of the work, but I guess that can only happen with raid cards that present one disc to the OS. > How about something like this: > http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=330240176734 > (PERC 5/i SAS RAID controller HBA, PCIe x8, 256MB RAM) -- $120 > > This should give you ~300-400 MB/s with your 5 drives.

I think I might first focus on a motherboard that has a well supported IO chipset. If I can get over 200Mb accross the whole array then I'll be happy. After that I will look at a decent quality raid card. -D
