How to fix I/O blocking on Great Wall GW3300 1TB in Fortnite?
Seeing my read speeds capped at 2000MB/s felt like a slap in the face. The GW3300 1TB has an outdated firmware scheduling algorithm that causes I/O request timeouts once the queue hits 64, making my frame rate jitter violently around 60 FPS. I tried enabling 'Low Latency Mode' in the drivers, but while I gained 2 FPS, the input lag became unbearable. I finally flashed the latest manufacturer firmware and forced the M.2 slot to Gen3 in the BIOS. In bandwidth tests, sequential reads shot up to 3200-3400MB/s, and the game finally felt fluid. I did notice the drive waking up randomly from sleep after the update, but disabling the power-saving mode killed that bug. Now it stays at 48-55℃ with response times down to 32-38ns. The hardware panel confirms the I/O mode is fully unlocked at 32-38ns.
