Thank you very much for filing this report and making Ubuntu better!

It used to be that a megabyte was 1024 kilobytes and a kilobyte used to be 1024 bytes. Nowadays a mibibyte is 1024 kibibytes and a kibibyte is 1024 bytes. On the other side a megabyte is nowadays 1000 kilobytes and a kilobyte is 1024 bytes. If you will look at your screenshot, you will notice that the shell refers to MB (megabytes) and g-s-m refers to MiB (mibibytes).

The shell reports 4.6 MB/s. That is (4,6 * 1000 * 1000) / (1024 * 1024) ~= 4,4 MiB/s.

Technically, both applications are right and therefore I have to mark this entry as Invalid. It will take time until one of the conventions to define size will win.

In spite of that, please proceed contributing to Ubuntu. The only thing I can offer is a laugh: the good old 1.44 MB floppy storage size consists of 1.44*1024*1000 bytes ;)

If the root of the differences between the values isn't due to MB and MiB, feel free to reopen this ticket.
