Perhaps that will offload the CPU. Loading PCI bus with more plain SATA controllers? Don't expect any positive results. 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. It might not work with your mainboard, though -- but there's a trick to isolate SMBus pins the card edge connector (search the Net). > -D [SorAlx] ridin' VN1500-B2
