Hello , I spent 2 hrs. on the phone with support and noone could help. They're escalating but I thought to try here. MB Crosshair 8 Dark Hero, CPU Ryzen 9 5900x, Memory Corsair vengeance (2x32) 3600, Gpu Asus TUF 4080 OC, PS EVGA P6 1000W Platinum and Win 11 Pro. I also have a WDsn 850x 2tb primary drive that runs perfect (94% of advertised speeds. Then I have a 2nd identical drive for M.2-2 slot. This 2nd drive gets reads of 2.29 gb/s out of possible 7.3 gb/s. The wite is also slow about 5.0 gb/s out of possible 6.6 gb/s. The second drive has been RMA'd and I received a new one, same problem though.Chipset, Storage and bios are all updated. If anyone can please help !
