How do I stop the brief screen freezes during save operations in Metaphor: ReFantazio on my Seagate FireCuda 530 1TB?

During long gaming sessions, I noticed the screen would hang for about 0.5 seconds during saves—a tiny glitch that becomes incredibly grating during fast-paced gameplay. On the FireCuda 530, when free space drops below 15%, the cache reclamation mechanism causes a massive I/O block, with latency jumping from 2ms to 45-60ms. I tried disabling the write cache in system properties thinking it would be more stable, but that just tripled the save time—a cautious mistake that backfired completely. I eventually cleared 200GB of junk files, defragmented the drive, and re-enabled high-performance write mode in Device Manager. AS SSD benchmarks showed write speeds climbing from 1200MB/s back up to 3100-3400MB/s, and the save stutters are gone. There was a bit of lingering lag for the first ten minutes while the file index rebuilt, but it smoothed out. Drive temps are stable at 45-52℃. After 10 consecutive stress-save tests, I/O latency is back to normal and random reads are steady at 120-140MB/s.
