I'm getting really bad speeds on my new SSD 980 PRO. It's running on a STRIX Z270E Gaming Motherboard with a i5-7600k CPU. I don't know if it has to do with running on the 2nd m.2 slot.

I get that it's a 3rd generation m.2, but my 960 EVO is outperforming the new drive.

Reading the manual is the best way of figuring these kinds of things out.

"1 x M.2_1 Socket 3 with M key, type 2242/2260/2280/22110 storage
devices support (both SATA & PCIE 3.0 x 4 mode)*
- 1 x M.2_2 Socket 3 with M key, type 2242/2260/2280 storage devices
support (PCIE 3.0 x 4 mode)**"

"The M.2_1 socket shares SATA_1 port when use M.2 SATA mode device. Adjust
BIOS settings to use a SATA device.
** The M.2_2 socket shares SATA_56 ports when use M.2 PCIE mode device in X4
mode. Adjust BIOS settings to use SATA devices."

Tldr yes it's because you used both slots.
