I doubt I would need their software for non raid use, so maybe it wouldn't matter. I'm considering using a software raid (server 2k3) or simply jbod. This isn't going to be a complex setup, so I wasn't looking for a higher class card like a 3ware, etc. It'll become another backup location for my main systems accessed via GigE network.
This card will be going in my PowerEdge sc420 which is limited to two onboard SATA ports and I'd like to expand on it. I guess I could use the PCIe 8x slot for the 4x card (I think they are backward compatible).
