Sorry my mistake (corrected) yes a sata drive. Ah ok I'll go for a nvme drive then! Once again thanks for your help guys now to find a 500gb in a black Friday dealI think you mean a sata m.2 drive. No, an nvme drive will still be faster with the constrained bandwidth.
Yes your board will boot with the NVME in it as long as you got the latest BIOS installed.
I have a similar board Z97X-UD3H-BK , which i got just brought a 1TB Samsung 970 Evo on a deal and installed and booted without issue. If you are not running any other drives like me. I have switched off the ACHI/RAID options on my BIOS and it still runs about 800MB/s for read/writes.
Vs a SATA SSD , its slightly more snappier but i was more needing the capacity than the speed.
