Reaching a dead end trying to figure out the issue with this system.
Brand new fresh install of Win10 Home.
Plextor M8PEg 512GB in the M.2 slot
Mushkin Reactor 1TB on a SATA
Both SSDs new for this system.
The Reactor runs AS SSD normally, and gets benchmarks you'd normally expect for it.
Seq r / w = ~500 / 400 MB/s
4k = ~30 / 100 MB/s
4k-64 = ~270 / 240 MB/s
access = 0.035 / 0.045 ms
overall pretty normal.
But the M8PE is showing abysmally low random write performance:
Seq r/w = ~800 / 250 MB/s
4k = ~35 / 2.8 (yes, 2.8) MB/s
4k-64 = ~167 / 5.5 MB/s
access = 0.33 / 1.55 ms
It's not just a little bit low, something is not right at all, and I can't seem to figure it out. There's no BIOS options I could find in the BIOS (MSI Z97 Gaming 5 board with a 4770k) pertaining to the M.2 configuration. AS SSD does show the driver as the NVMe driver (stornvme). Install is literally a fresh install, install drivers, perform windows update and then benchmark. Nothing else on the system.
Anyone have any ideas?
