Enterprise hard drives will probably work quite nicely with the Pegasus, because they will be better equipped to talk well with the RAID controller. It's unfortunate there aren't more enterprise drives on the Pegasus compatibility list. (I believe only the Toshiba drives on the list are classified as "enterprise".) I wanted to stick exclusively to the compatibility list and work within a limited budget, so I went with the 3TB Seagate disks.
