My emulator keeps hitting I/O blocks and lagging out while loading games on the GW3300 256GB, how do I fix this?

While running a high-res emulator, I noticed a weird 0.8-second micro-freeze every time a save file loaded, which felt incredibly janky. The random read speeds on the Great Wall GW3300 256GB were all over the place when handling fragmented ROMs, with latency jumping wildly between 60ms - 120ms. I first tried disabling all background indexing services in the OS, but it only shaved off about 0.2 seconds—basically zero perceptible difference, which was honestly frustrating. I then dove into Device Manager, switched the disk write caching policy to 'Quick Removal', and manually locked my virtual memory to an 8GB high-speed partition. Checking RTSS, the frame time tightened up from 15-40ms down to a rock steady 10-14ms, and that initial hitch completely vanished. Interestingly, when I first tried disabling the cache entirely, the system nearly locked up during save writes, and it only stabilized once I went back to Quick Removal. Drive temps stayed chilled at 38℃ - 45℃ with normal load. A quick run through CrystalDiskMark showed a 12% bump in 4K random reads, and the scheduling parameters are now locked in.
