My Zhitai TiPro9000 1TB is hitting a cache overflow while building in Sims 5. Need a fix?

The cache management on this drive is a joke. Once you write over 50GB, the speed tanks from 7000MB/s to 900MB/s, which causes the game to chug during loads. Honestly, the way the manufacturer handled the SLC threshold for the 1TB model feels lazy. I tried enabling write caching in Windows, but the system just froze—a reckless move that taught me to go deeper. I ended up splitting the drive into two 500GB partitions and enabled NVMe Fast Boot in the BIOS. In high-load stress tests, random read speeds stayed between 60-70MB/s without that cliff-dive drop. I did lose access to some saves after the re-partition, but re-mapping the file paths sorted it out. Drive temps are holding at 48-55℃. I exported the disk management config so I don't have to do this again, and temps remain at 48-55℃.
