Bug Description
The current version (UDisks 2.8.2, ubuntu 19.04) of gnome-disks shows too low write speed for my new nvme m.2 ssd Samsung 970 pro.
It shows write rate 583,6 MB/s but it must be 2.7 GB/s
The read rate is OK (3.3 GB/s).
Results are in attached screenshot.
To make sure that this is not hardware/kernel issue, I used fio benchmark:
fio --name TEST --eta-newline=5s --filename=
<...>
WRITE: bw=2592MiB/s (2718MB/s), 2592MiB/s-2592MiB/s (2718MB/
I also compared with the results of the same utility from ubuntu 16.10, and there the rates are fine (write 2.7 Gb/s, read 3.2 GB/s)
