Why do SMB transfer speeds fall off a cliff after a few minutes?
yea, the PNY CS900 is actually a low quality cheap DRAMless SSD, so, it might actually be whats causing it. They are known to drop off terribly once they hit 50% full, and they have issues maintaining decent write speeds over long writes.

PC lagging but can't find root cause even stress test
Your stress tests mean nothing if the issue is intermittent and not load-dependent. Random stutter + freeze, no thermal throttle, normal usage readings? That screams storage I/O hiccups or power delivery instability. That PNY CS900 SSD is a known weak link. DRAM-less, budget-tier, and it WILL choke
