My Kioxia EXCERIA PLUS G4 has wild response swings in low-load areas of Valorant. Should I lock the PCIe link?

One second I'm hitting a perfect headshot and feeling the rush, the next, a random frame drop kills my momentum. The I/O scheduling on the Kioxia EXCERIA PLUS G4 is way too aggressive with fragmented resources, causing read response times to bounce between 1ms and 20ms. This pushed my frame times from 11ms up to a jarring 32ms. I tried disabling all background apps in Windows, but the I/O spikes didn't budge—just a waste of effort. I went into the BIOS, disabled PCIe Link State Power Management, and forced the drive into High Performance mode. Monitoring with RTSS, the frame time jitter dropped from 10-30ms to a tight 12-15ms. The game feels way more responsive now. My idle drive temp jumped by 5℃ after killing the power management, but I adjusted my case airflow to compensate. Drive is steady at 52-58℃, motherboard at 60-66℃. The scheduling mode is finally locked in. My aim feels consistent again.
