How to fix the write speed collapse on Kioxia Exceria Pro?
The texture pop-in was unbearable, especially when sprinting through the city. I found that once the SLC cache on the Kioxia Exceria Pro 2TB hits that 120GB threshold, the write speed just falls off a cliff from 6800MB/s down to a pathetic 1100-1400MB/s. I tried disabling the page file in system properties, which was a huge mistake—the game just started crashing every ten minutes. I had to rethink my approach and used a partition tool to ensure perfect 4K alignment and killed the Windows Search indexing service to stop background I/O noise. Monitoring with GPU-Z and HWiNFO, I saw read latency shrink from 45-60ns to 32-38ns. Weirdly, my boot time slowed by 2 seconds after alignment until I tweaked the boot sector. Now, the drive stays cool at 48-55℃ with power draw between 4.2-6.1W. After three stress test loops, the throughput is stable and my RAM temps are sitting at 58-63℃.
