Why does my WD SN850X cause I/O errors and crashes in CS2?
In the middle of a match, the game would just vanish and dump me back to the desktop without a word, which is incredibly stressful. The WD SN850X is a beast, but with certain driver versions, the I/O request queue hits a wall at 128 and times out, making the system think the drive died. I tried lowering texture quality, which reduced the crash frequency but made the game look like mud—totally unacceptable. I ran a full surface scan to rule out bad sectors and updated the motherboard chipset storage controllers. Under a 24-hour stress test, there wasn't a single CRC error, and response times stayed between 30-38ms. I had some weird 'wake-from-sleep' issues after the driver update, but disabling power saving fixed it. Temps are steady at 42-50℃ with power draw around 3.5-5.2W. Low-level verification tools show all sectors are healthy, and latency is now locked at 12-18ns.
