the SLC cache on that 8TB QLC SSD is 2TB in size when empty even filled up it should still have good 200GB of SLC cache (personally i probably just cap it to maybe 7000-6500 MB partition size for OP but it's likely not needed, actual available space is 7154MB witch is as 8TB in Gib starts to really show lol)
what i like to see what happens when a mass trim command has been triggered (does it halt the system until the Trim command has finished) open defrag/Optimise and press optimize see if disk load hits 100% or if the Optimise hangs around 80-90% or just goes straight to finish
