I keep getting these random read latency spikes during fast travel in Elden Ring, why is this happening?

While fast traveling through the Lands Between, I hit these bizarre 200-400ms freezes that completely killed the immersion. The issue is that once the Zhitai TiPro9000's dynamic SLC cache hits its threshold during heavy fragmented file R/W, the random read speeds tank from 7000MB/s down to about 1200MB/s, creating a noticeable gap in asset loading. I initially tried disabling unnecessary Windows services, but that only shaved off 0.5 seconds—a total waste of time that didn't touch the NAND scheduling bottleneck. I eventually dove into Device Manager and manually bumped the NVMe controller queue depth to 2048, while simultaneously killing the HDD power-saving mode in the power plan. In CrystalDiskMark, my 4K random reads tightened up from a shaky 45-52MB/s to a steady 68-75MB/s. The game finally feels fluid. I did run into some weird recognition delays right after the first queue depth tweak, but a firmware update sorted that out. Temps are sitting between 42-55℃ with the stock heatsink. Verified the R/W curves are finally flat via a storage analyzer.
