Hi,
Current QLC drives are total shit in terms of steady-state performance.
First 10-100 GB of data is written into the SLC cache which is fast, but
then the drive switches to its QLC memory and even the linear write
performance drops to ~90 MB/s which is actually worse than with HDDs!
So, try to run a long linear write test and check the performance after
writing a lot of data.
Last monday I performed a quick test with those two disks already,
probably not that relevant, but posting it anyway:
