I have a very fast Samsung NVME drive hosting my root file system.
During backup 'atop' often shows 100% usage of my NVME drive while  
reading only a few MB/s and
several thousands 'Read' ops (during 10 seconds).

Is this normal or a measuring bug of 'atop'.

Stand alone timing tests have shown that this drive can read some GB  
per second.

What's happening?

Many thanks for a hint,
Helmut
