Slow M.2 SSD

[mannychap]

HI,

I have a Gigbyte GA-Z97X_UD5H Motherboard, Samsung EVO 850 plugged into the Sata Express port, and I have just installed the Samsung 970 Evo NVMe M.2 into the motherboard. I ran the samsung magician utility and while I am seeing fast read/write times for the 850, about 5200/4480 the 970 is only clocking about 830/800. Does anyone have an idea about how I can address the slow speeds?

1. You can't use the m.2 port at the same time as the SATA Express port

2. That m.2 port is only x2, and as such, will NOT give full performance with that 970 drive.

3. the "5200/4480" number you're seeing for the 850 is because you have RAPID mode turned on. That is mostly reading your RAM speed, not the drive.
