Is my Great Wall GW3300 512GB experiencing read latency after long sessions in Neverness?

I've always been cautious with this entry-level Great Wall GW3300, especially since loading times in Neverness spiked once the drive hit 80% capacity, making me worry about severe performance degradation. I started by manually clearing 50GB of junk files, but the loading lag persisted, and the experience still didn't feel fluid. I then fired up the GamePP System Backup & Config Export Tool's health check to scan the drive, discovering that data blocks were too fragmented, which increased seek times. I carefully ran the 'Space Distribution Optimization' in GamePP to rearrange core game files and performed five consecutive read/write stress cycles.
