How to resolve I/O blocking on YMTC Zhitai TiPro9000 4TB?
Cruising through Night City at high speeds, I kept getting this subtle screen tearing that was incredibly distracting in 4K. The YMTC Zhitai TiPro9000 4TB is huge, but it was struggling with real-time streaming assets, causing I/O request queues to pile up between 15-22ms. I tried turning off all ray tracing, but the stutters stayed and the game looked worse—definitely the wrong move. I went into Device Manager, disabled the 'write cache buffer flush' policy, and updated the NVMe drivers. RivaTuner showed my frame times tighten from a messy 14-32ms range down to 8-12ms. I actually set my virtual memory to 0 by mistake and the game crashed instantly, but resetting it to system-managed fixed the stability. Temps are steady at 48-54℃. 3DMark storage tests confirm the throughput is finally where it should be, and RAM is at 58-63℃.
