How to fix Seagate FireCuda 530 cache overflow in PUBG?
In the middle of a drop-zone fight, the game looks smooth, but every few seconds there's this tiny, annoying twitch. It's an unsettling feeling. Monitoring showed that when the Seagate FireCuda 530's SLC dynamic cache fills up during high-frequency resource loading, the random read speed crashes from 6000MB/s to 1200MB/s, creating a 18-35ms command delay. I tried turning on 'Game Mode' in Windows, but that just bumped CPU priority without touching the disk bottleneck—not nearly enough. I updated to the latest NVMe controller driver and enabled the forced write-cache flushing policy in Windows Performance options. In AIDA64 random read tests, 4K reads stabilized at 62-78MB/s, and the twitching vanished. I had some weird drive detection delays at idle right after the update, but switching the power plan to High Performance fixed it. Drive is at 48-55℃, motherboard at 52-58℃. The cache scheduling is finally synced. It's a relief to actually drive without lagging.
