How to optimize I/O throughput for the Kioxia G4 1TB SSD?
In the middle of Arrakis' sandstorms, my character felt like they were stuck in glue, hitching every five seconds. It was a disaster. Despite the high rated speeds, the Kioxia G4 1TB queue depth was idling between 1 - 4 during non-linear random reads, barely touching the PCIe 5.0 bandwidth. I tried moving the game to a SATA SSD for comparison, and load times tripled, which proved the issue was definitely the scheduler. I pushed the driver parameters, cranking the max concurrent requests from 32 up to 128 and killing the Windows Indexing service. In AIDA64 random tests, IOPS skyrocketed from 450K to 820K, and the scene transition stutters vanished. I did trigger a Blue Screen (BSOD) the first time I bumped the queue depth, and I had to loosen my RAM timings by 200MHz to keep it stable. Drive temps are now 62℃ - 67℃ with the fan screaming. I exported the peak read/write logs to verify the fix, though the fan noise is a bit annoying.
