My Zhitai TiPro9000 4TB keeps hanging during large building loads in Nightingale due to cache saturation, how do I fix this?

That feeling when the loading bar just stops dead while loading a massive scene is the worst; it turns excitement into pure anxiety. Digging into the data, I found that once the Zhitai TiPro9000 4TB hits over 200GB of continuous writes, the SLC cache bottoms out and random read speeds crater from 7000MB/s to around 1200MB/s. I first tried increasing the virtual memory page file, but that was a total disaster—it didn't fix the lag and just kept my disk I/O pegged at 90%+. I realized I had to tackle the underlying cache. I installed the latest NVMe drivers and disabled the write-cache flush policy in Device Manager. In CrystalDiskMark, 4K random reads jumped from 45-52MB/s to 68-75MB/s, and loading times dropped from 18 seconds to 11 seconds. I did experience some brief recognition delays during standby right after disabling the cache, but switching the power plan to 'High Performance' cleared that up. Drive temps stayed between 42-55℃ with the heatsink doing its job. After 10 consecutive load tests, the speeds are back, though memory temps hovered around 58-63℃.
