Dealing with write latency on Kioxia EXCERIA PRO 2TB
Saving in this game feels like running a benchmark on my SSD; every time it autosaves, the screen just hangs for half a second, which is absolutely wild. Once the SLC cache on the EXCERIA PRO 2TB hits that 100GB limit, the write speed craters from 5000MB/s to around 1200MB/s, and that performance cliff just blocks the game's main thread. I tried disabling all background updates in Windows, but the save stutters persisted—that kind of 'optimization' was a total waste of time. I eventually went into the registry to force a write-combining strategy and used a pro tool to clear about 200GB of redundant fragment space. In IOPS stress tests, random write latency dropped from 120us to 85us, and those micro-stutters finally died. I actually bricked my boot sequence once after the registry tweak and had to use a recovery drive to restore my backup, which was a heart-stopping moment. Temps are sitting at 51-58℃, and the heatsink is barely keeping up. Exported the logs, and fan speeds are steady at 1400-1600RPM.
