Seems like Microsoft has yet to fix the write speeds of NVME drives. Read speed is fine at 7400MB/s, but no matter what PCie4 NVME drive I try, the max write is always 2400MB/s. Reinstalled WIndows, used Windows 10 and 11, flashed Bios, updated chipset driver, left standard drivers. No change. Before windows updates in November 2021, speeds were 6800MB/s. So whatever they "fixed" made it worse. Its on a X570 chipset, 2 M2 slots. Also doesnt matter what slot is used, one, two, or both. Read speeds are normal. Write speeds suck. And yes, all set to PCie 4.
