Your correct about that. As for the original posters question I also know of no SATA PCI card that is non-RAID. However, it is possible to pick up used Adaptec 1200A pci RAID sata card off Ebay for about $15, all this is, is a re-branded Highpoint 1520 card and will work with FreeBSD. For some reason the equivalent Highpoint cards sell for a little more on Ebay. I personally don't understand the bias against these cards in the Windows community but there obviously is some. Adaptec discontinued these cards a while back, perhaps that is why. Ted
