How to optimize DRAM cache on Fanxiang S910PRO 2TB?
This drive is ridiculously fast, but in The Sims 5, it manages to make you feel a drop from 100 FPS to 10 FPS in about three seconds. The Fanxiang S910PRO 2TB has a huge independent cache, but when hitting massive amounts of small files, the sync between the controller and cache had this microsecond desync that sent I/O wait times through the roof. It was almost comical how bad it was. I tried switching the BIOS to Gen4 mode; it stopped the hitching, but it cut my speeds in half, which felt like a cruel joke. I finally flashed the official 1.04 firmware and disabled the Windows disk power-saving mode. Looking at the RTSS frame time graph, those jagged spikes were completely flattened, and frame times stabilized at 14-18ms. I did notice the drive ran about 5℃ hotter at idle after the update, but I just tweaked my fan curve to deal with it. Temps are now 55-62℃. I exported the logs and everything looks clean.
