Just becareful when suggesting that, as alot (3 to 1 ratio) of users are actually on laptops then desktops, so there is no way to install 4 SATAs, plus a second controller for the DVD Sata connection (5 Sata). Most people still have RAID listed but the risks (Raid breaks NO DATA is recoverable ever) outway the benefits. If you had 4 SATAs anyway, be better to be in RAID 5 so you can hot swap the drives if one fails and never lose data.
