Why is my Kioxia Exceria Plus G4 slowing down during Apex updates?
Having a 2TB drive is useless if the write speed becomes a joke once it fills up. The Kioxia Exceria Plus G4 tanks hard when usable space drops below 15%; the lack of OP space triggers aggressive garbage collection, crashing my write speeds from 6000MB/s to a pathetic 800MB/s. I tried using file compression to save space, but that just spiked my CPU to 90% and made the whole system lag—a total waste of time. I eventually nuked all my unnecessary software to get free space above 30% and used a partition tool to leave 50GB as unallocated space. Sequential writes bounced back to 5200-5800MB/s, and the hitching during map loads vanished. I did have some backup software throw a fit because the total disk size changed, but re-mapping the paths fixed it. Temps are sitting at 40-50℃ with read latency at 50-65ns. The system snapshot confirms writes are now stable at 5.2-5.8GB/s.
