Not sure this helps you (since it sounds like you want a desktop mobo with socket 115x), but you can buy a clevo/sager laptop with 2 mSata slots (plus a third pci-e-based mini-card slot for wifi). The model-numbers (sager-style) that I know of are NP9390, NP9380, NP8295, NP8275, NP8255, NP8235, NP7330, but there could be more where those came from, or from other vendors. Rather than a desktop socket, these would use something like the i7-4700MQ laptop cpu and the HM87 chipset. You could use the two mSata slots for RAID-1, or RAID-0, but if you are looking for RAID5/RAID10 setup you would fall short. Have you considered pci-e based SSD units, like the ones used in blade servers? Not as compact as mSata, but might work. What...
