I'll look at the link, thanks. my current intention is linux, software raid, raid5, and sata 2. I already have a disk array on-site from dell using scsi drives on another box. I like scsi, but for the disk density I'm thinking the largest drive I can easily get is 146gb. Sata drives I can get in 500gb or 750gb and the cheaper price for the sata drives make the sata drives more attractive than scsi drives.
