Why is my WD Black SN850 hitching during fast travel?
Whenever I hit a crowded town, the loading bar just hangs there—it's a total nightmare for anyone trying to play seriously. While the WD Black SN850 2TB has insane theoretical specs, my HWiNFO logs showed response times swinging wildly between 12-28ms when handling small file fragments. I tried disabling Fast Startup in Windows, but that was a waste of time and actually added 3 seconds to my boot. I eventually grabbed the Western Digital Dashboard, flashed the latest firmware, and forced my motherboard power plan to 'High Performance'. In CrystalDiskMark, my random 4K reads jumped from 62-71MB/s to a solid 88-94MB/s, and those annoying stutters vanished. I did hit a snag where temps spiked to 72-76℃ right after the update, but tightening the heatsink mount brought it back down to 58-64℃. With the I/O queue depth stable at 32-64, the data flow is finally seamless. My frame time is now locked in at 5.1-6.4ms, making the whole experience feel rock steady.
