I bought that SSD when I was on Windows 8.1, with MSI B250M motherboard. Everything was perfect, with the usual speed 300-400MB/s
Then I installed latest Ubuntu 18.04, performance went to garbage grade - for SATA SSD only. M2 is not affected at all. It's barely 30-40MB/s and at that rate the system almost freezes as new disk I/O operations are blocked.
Then Windows 10 and Server 2019. Same problem.
Then a BIOS upgrade and change of interface in BIOS from AHCI to Optane. Speed problem is now solved, but I/O blocking problem remains. When I copy file at 30-40MB/s the entire Windows is slowed down (usable, at least new apps can open).
I Haven't seen anything similar to be honest, but I'll take a look later today.
