Fixing read latency on Fanxiang S790 4TB in KCD
Walking through the crowded town streets, the game would just hitch for a second. It's incredibly jarring when you're using a massive 4TB drive. The Fanxiang S790 was hitting 90-120ms latency when reading fragmented files, meaning the assets couldn't load fast enough for the renderer. I tried the built-in Windows defrag first, but again, that's useless for NVMe and just wastes write cycles—a frustrating mistake that taught me partition alignment is the real key. I used a professional partition tool to force 4K alignment and updated the storage drivers to the latest stable build. In AIDA64, random read latency dropped from 105ms to 62-70ms, and the loading hitches are way less frequent. I actually lost a few old save files during the re-partitioning process, which was a nightmare until I restored them from a backup. Temps are now 38-45℃ with a load of 50-70%. Analysis tools confirm the response time is much better, and memory temps are steady at 58-63℃.
