M.2 storage and Intel Rapid Storage Technology vs AHCI

[robertlein88]

Hei

I'm running Samsung 970 EVO 250GB in M.2_1 socket (OS installed on this one) and EVO 500GB in my M.2_2 socket. The motherboard I'm using is ASUS ROG STRIX Z370-F.

I'm using AHCI right now, but should I use IRST?

IRST is meant for RAID configuration or optane configuration, you have the right bios choice for your M.2 NVMe SSD.

Thanks. Yea it seems to work as advertised. I've used Samsungs software to test the speed of M.2 and it seems to work well after I changed it from x2 to x4 in the bios. I was just curious about which mode was best.
