X61T Mini PCI Express SSD?

[KosanRio]

Hi! I recently installed a modded BIOS to remove the Whitelist and now I have a free Mini PCI Express slot. I understand "mSATA" SSDs will not work, I've been told there are actual Mini PCI Express SSDs that have their own SATA controller, Can you boot off of these directly? Thanks.
Also does anyone know if the Mini PCI Express slots are v.1 or v.2 of PCI Express?
