Fixing I/O blocking on Zhitai TiPro9000 4TB in The Division
I can't believe a top-tier 4TB drive was dropping my frames down to 30 during a firefight; it was a joke. While the Zhitai TiPro9000 has insane throughput, its handling of small file requests was getting bullied by my background antivirus. I tried cranking the textures to Ultra, which actually made the drops worse—classic case of making things worse by trying to 'fix' them. I went into Task Manager, forced the game process I/O priority to High, and killed all real-time disk scanning. In the monitor, read/write latency instantly shrank from 35ms to 8-12ms. I did hit a brief system deadlock right after the first tweak, but a reboot and disabling Fast Startup cleared it up. The drive runs between 58-65℃, and the heatsink is definitely warm. I exported the peak logs to verify, and the fan is steady at 1400-1600RPM.
