How to fix cache-related lag on a Zhitai TiPro9000 2TB?
Watching that loading circle spin forever was honestly testing my sanity. Once the SLC cache on the Zhitai TiPro9000 2TB fills up with temp files, the write speed collapses from 7000MB/s to around 1000MB/s, which is just a joke. I tried clearing system temp files first, but it only saved me 0.2 seconds—completely useless. I eventually installed the latest manufacturer NVMe drivers, disabled unnecessary indexing services in Windows Disk Management, and switched the write cache to forced flushing. CrystalDiskMark showed random 4K reads improving from 52-60MB/s to 68-76MB/s. I did notice that file searching became slower after disabling indexing, but I fixed that by manually re-indexing my critical game folders. Drive temps are holding at 46℃ - 54℃. I've exported all the latency data via a performance analyzer to make sure the cache scheduling is actually working.
