Why does my Zhitai TiPro9000 1TB write speed tank during large patch updates in The First Descendant, causing slow loads?

That anxiety of watching the loading screen freeze at 99% is a nightmare, and I eventually realized the write bottleneck of my storage was the culprit. On the Zhitai TiPro9000, once the SLC cache overflows during massive 100GB+ data writes, the speed plummets from 7000MB/s to around 1200MB/s. I initially tried using some third-party disk optimization software for a forced defrag, but that actually pushed write latency up to 120ms—a complete step backward that left me feeling totally lost. I then grabbed the latest official firmware and manually configured the write cache strategy, setting the buffer size to 4GB. In CrystalDiskMark sequential tests, random write speeds jumped from 42-55MB/s to 88-102MB/s, slashing load times by nearly 40%. To make matters worse, the system didn't even recognize the drive right after the firmware update until I physically reseated the M.2 slot. Drive temps are now hovering between 48-55℃, and the heatsink is doing its job. Benchmark tools confirm the low-level instruction set is synced, though memory temps stayed between 58-63℃.
