Measure the disk performance / speed on Home Assistant OS?

Which is the best way to measure the disk performance / speed if I am running Home Assistant OS?
dd does not work and system monitor does not provide any disk speed KPIs.

Cheers, red

Hallo, any idea how to measure storage speed (SD card, SSD) reliably when using Home assistant OS?

I have this question too. Did you find any way since ? Thanks!

me too. Still looking for the same thing, haven’t found anything.

My image writing software seemed slow, looks like they operated at usb2.0 speeds for whatever reason. Wanted to check the diskspeed when connected to my Pi with HA-OS

first do a write test

dd if=/dev/zero of=/data/testfile bs=1M count=1024 oflag=direct

then do a read test

dd if=/data/testfile of=/dev/null bs=1M count=1024

then erase the test file

rm /data/testfile
