[Desktop-packages] [Bug 1836405] Re: too low write rate by gnome-disks' benchmark
Thank you for your bug report, could you report it upstream on https://gitlab.gnome.org/GNOME/gnome-disk-utility/issues ? ** Changed in: gnome-disk-utility (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-disk-utility in Ubuntu. https://bugs.launchpad.net/bugs/1836405 Title: too low write rate by gnome-disks' benchmark Status in gnome-disk-utility package in Ubuntu: New 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.
