I have all the SATA ports on this board populated. I do not use a RAID array. I am eager to purchase/install the new Samsung 960 EVO 250GB PCIe M.2. I am aware that this disables SATA ports. When reviewing forum posts, people most often report that each M.2 drive installed disables two SATA ports. The manual for this board seems to suggest otherwise. I need fresh eyes to confirm how many SATA drives I lose if I put an M.2 drive in the M2A slot. To me it looks like installing the M.2 drive in the M2A slot disables the SATA3_0 port only making this a viable upgrade for me.
