Hi,
Can you test it slightly differently (and simpler)? Like in this
googledoc:
https://docs.google.com/spreadsheets/d/1E9-eXjzsKboiCCX-0u0r5fAjjufLKayaut_FOPxYZjc/edit#gid=0
As we know that it's a QLC drive, first let it fill the SLC cache:
fio -ioengine=libaio -direct=1 -name=test -bs=4M -iodepth=32 -rw=write
-size=100G -filename=/dev/sdXX
Then, immediately:
1) Parallel random write
fio -ioengine=libaio -direct=1 -name=test -bs=4k -iodepth=32
-rw=randwrite -runtime=60 -filename=/dev/sdXX
2) Transactional random write (journaling)
fio -ioengine=libaio -fsync=1 -direct=1 -name=test -bs=4k -iodepth=1
-rw=randwrite -runtime=60 -filename=/dev/sdXX
3) Linear write
fio -ioengine=libaio -direct=1 -name=test -bs=4M -iodepth=32 -rw=write
-runtime=60 -filename=/dev/sdXX
4) Parallel random read:
fio -ioengine=libaio -direct=1 -name=test -bs=4k -iodepth=32
-rw=randread -runtime=60 -filename=/dev/sdXX
5) Synchronous random read:
fio -ioengine=libaio -sync=1 -direct=1 -name=test -bs=4k -iodepth=1
-rw=randread -runtime=60 -filename=/dev/sdXX
6) Linear read:
fio -ioengine=libaio -direct=1 -name=test -bs=4M -iodepth=32 -rw=read
-runtime=60 -filename=/dev/sdXX
Hi,
So, ran the fio commands, and pasted output (as it's quite a lot) here:

I hope someone here can draw some conclusions from this output...
