I'm getting these random read/write spikes on my Samsung 9100 PRO 4TB when entering big towns. Why?

While exploring the map, I kept hitting these sudden, jarring micro-hitches that were absolutely brutal in 4K. Checking HWiNFO, I saw the Samsung 9100 PRO 4TB random reads jumping between 12-22ms, which totally choked the asset streaming. I tried bumping the page file to 64GB, but that was a complete waste of time; my frames actually tanked from 75 FPS down to 58 FPS. I eventually dove into Device Manager and pushed the NVMe controller queue depth from 1024 up to 2048, and killed the PCIe Link State Power Management in the BIOS. After running CrystalDiskMark, my random 4K reads jumped from 65MB/s to the 82-88MB/s range, and town load times dropped from 15 seconds to a crisp 6 seconds. It wasn't a smooth ride though—the drive had some weird detection lag at idle until I switched the Windows power plan to High Performance. Temps sat around 48-56℃, and the heatsink felt pretty warm to the touch. I exported these verified parameters to a config file, and now my frame times are rock steady at 5.1-6.4ms.
