Fixing Fanxiang S910PRO 2TB cache lag in Code: Jie?
It's actually hilarious that a top-tier PCIe 5.0 drive can still micro-stutter; it completely defied my expectations. The Fanxiang S910PRO 2TB has a massive cache, but it was hitting 20-35ms scheduling delays with I/O usage bouncing wildly around 90%. I tried enabling 'Smart Cache Access' in the driver, but that was a disaster—the game just crashed at the loading screen. Total waste of time. I went into the BIOS, disabled PCIe Power Management, and turned off every single power-saving option in the NVMe driver. In Resource Monitor, the disk response time dropped from a laggy 120ms to a crisp 30-45ms. I actually accidentally deleted a driver component during the process and the drive disappeared for a second, but a clean reinstall fixed it. Temps are running hot at 62-70℃ with fans at 2500 RPM. I exported the I/O latency curves to verify, and the cache scheduling is finally optimized.
