I would like to get a M.2 drive to dual boot Linux with my existing Win 10 install, I'm running out of places to put drives so that little M.2 slot looks handy. I have an ASRock Extreme 4 x99 motherboard with a 5820K (so 28 PCIE lanes) and it's manual says it supports:
• 1 x Ultra M.2 Socket, supports M.2 SATA3 6.0 Gb/s module
and M.2 PCI Express module up to Gen3 x4 (32 Gb/s)
- If the Ultra M.2 Socket has been occupied, the internal S_SATA3_2 will not function.
- If M.2 PCI Express module is installed, PCIE5 will be disabled
It doesn't say anything about NVMe in the manual, so I assume it doesn't support it.
So will any of the M.2 SSDs I see work?
Does NVMe work as Gen3 x4 in a board that doesn't support it? I read in one article that it would work but not as a boot device?
I have 2 GPUs which would use 24 PCIE lanes, is using the 4 remaining going to cause an issue if there are no other PCIE devices present?
I don't need blistering speeds for my purpose, SATA is probably fine. but some of the cheaper SATA M.2 drives seem to have poor write performance when I look at reviews?
