How to fix Fanxiang S790 4TB lag in Final Fantasy XV?
It's honestly a joke that a 4TB drive is struggling with loading times in this game; it's just pathetic. The Fanxiang S790 was suffering from poor partition alignment, causing random reads to bounce between 30-60MB/s, which led to those annoying freezes during scene swaps. I tried lowering the graphics settings to reduce the load, but the game looked like a pixelated mess and the stuttering stayed—a complete waste of time. I eventually used a professional tool to force 4K alignment and scrubbed all the old redundant drivers. Random reads jumped from 35MB/s to 52-58MB/s, and my 1% lows improved by about 12 FPS. I had a small issue where the total disk size looked wrong after the tweak, but a quick re-format of the boot partition fixed it. Temps are 45-55℃ with response times at 25-31ms. The input lag is gone and it finally feels snappy.
