Title:
  Improve performance by changing the block size to 8M

Status in usb-creator package in Ubuntu:
  Fix Released

Bug description:
  This issue is found in usb-creator 0.3.11 in impish.

  I found that creating USB disks in GNOME Disks is 2x faster than
  Startup Disk Creator, and here's the comparison:

  Startup Disk Creator: 1:52
  GNOME Disks: 0:37
  With a Sandisk Extreme Pro USB drive (CZ880) and a 4.0G image

  After I changed the default block_size from 1000000 to 8388608 in
  USBCreator._builtin_dd function in the Python file /usr/share/usb-
  creator/usb-creator-helper, this can improve the writing speed and
  making it about 0:30 to write the same disk image.
