So, the M.2 Socket is actually your fastest option. It's hooked straight to the PCI-e bus and I typically see sustained transfer speeds of about 3.6GB/s on those. Those have sort of replaced the SATA SSD as the fastest option, and 2TB is a pretty standard and affordable size (got one for $180 this past year).
You would be able to put that in your array and it would mitigate the expansion card need. There are also M.2 riser cards.
