Why does my Zhitai TiPro9000 stutter in New Eden forests?

I was curious if a top-tier 4TB drive could stay smooth, but I experienced 0.2-0.5s freezes while exploring New Eden, which totally broke my immersion. I tried disabling write cache flush in Windows; read speed rose by 2% per CrystalDiskMark, but it caused severe save file corruption after a power outage, which was devastating. I then used GamePP NVMe Queue Depth Configuration to raise queue depth from 32 to 128. Now, random 4K reads are stable at 88-92MB/s via CrystalDiskMark, latency dropped from 0.8-45ms per AIDA64, and temps stay at 42-50℃ per HWiNFO.
