The regular GT70 2PE Dominator Pro comes with three mSATA drives standard, but I haven't found anything to indicate that the 1461US has an option to mount mSATA drives in addition to the HDD. If you're willing to give up your HDD, you can get an mSATA caddy that plugs into your HDD drive bay and mount one or two mSATA SSDs, or an MSI Super Raid 2 caddy which will mount three mSATA SSDs. You'll want to check on availability of the caddy options before you order though.
