Here are my thoughts: The card itself was $175.00 and the 4 250GB brives were $150 bucks a piece, so the cost is considerable. If you are only going to have two disks mirrored, you can get the two channel card and two drives and mirror them which is obviously less money. My system is a Tyan Transport GX-28 with 2 Opteron 246's and originally I had the drives on the onboard controller. First, there is a very noticable increase in performance going from the integrated (software) raid controller to the hardware raid controller. For my percieved needs it was definitely worth the money. Second, its a nice reassurance to know that if a drive (or even two drives) fails the hardware controller can restore the array by popping in a new disk without me having to do much...I'm not sure if this is the case with the integrated or linux raid. With the hardware controller, if I wanted a bit more storage space, I could have chosen to make a raid five array, something that as far as I know is unavailable in both integrated and Linux array (at least now without a significant performance hit.) Hope that helps. Frank scotthathcock@comcast.net wrote: > I currently have an ASUS K8V Deluxe system with an 80GB SATA drive. It > used to have a old 10GB PATA disk for M$ dual boot.
