It just...Why???I thought it was high temp(without extra fan), but after I add the fan, the speed is still...

what the ram usage? could be running out of cache space

if u mean the host's memory, 9.5GB/16GB(DDR4 3733 dual-channel),i also check cpu usage while benchmarking, didn't touch 10% out of 100%.(12400kf)
mb is Z690 Phantom Gaming 4.

latest motherboard bios?

5TB written?

in Device manager, under disk drives/970/policies, is 'Enable Write Caching' still enabled?

After enabling caching on the disk, i still don't think this writing speed is normal...
so 500MB/s is the speed outside of caching then?
i firstly turn it off because windows always keeps file in the host memory when i using samba sharing saving things to the computer.

What are you doing that produces this slow speed? Or rather, where are you getting this number from?

Which benchmark are you using and which test is giving the apparently incorrect result?
