X99 With 2 M.2 Slots Online
Apr 20, 2015 Newegg's product photos & specification lists should provide enough info, although I've never seen such a dual M.2 slot X99 board. Also: I'm not so sure about the M.2 form factor's ability to avoid overheating. However: instead of wishing for a board with dual M.2 slots, maybe dual Intel 750 series PCIe SSD's would be a more practical possibility. What you need to watch out for is whether M.2 slot occupation reduces your active SATA port number. It should be on mobo manual somehwere. It mainly effect lower end mobo where the lane # gets tight. Top-end, Z-line (Z170, Z270, or even X99) shouldn't suffer from any issues. Personally, I see the only major benefit of M.2 is reduction of cables.
