Intel Optane 900P + Mojave = random system freezes under load

I recently upgraded from an M2 non-NVME SSD to a PCI-E Intel Optane 900p - I got it used from Ebay, but in good condition.

However, I'm very frustrated so far by the performance... when Spotlight is indexing, and I for example scan my disk at the same time... the system would freeze several seconds, but the mouse cursor would still move, though nothing else.

Has anyone experienced anything similar? The SSD is at least 5x faster in every aspect to the one before, so I do not comprehend why this would be happening?

Could I be missing a Kext?
