I've also run into this problem... When it was new I got full speed (write 4432MB/s). I did a random test yesterday since I thought a file was unpacking very slow, lo and behold, happy holidays to me, the drive suck.
I've updated to latest firmware (didn't help), deactivated and reactivated write cache, also ran the command a few pages back that fills the drive then trims. Didn't help..
Is there a fix on the way?
edit: Thought my specs would show automatically.
CPU: Ryzen 5 3600
Mobo: Asus B550-F Gaming
HDD: Corsair Force MP600 1 TB
edit2: found the PDF, I did all three steps, didn't help.
