Public bug reported:
(might as well be generic kernel / usb / laptop tools related but i am
especially suspecting NTFS)
Yesterday I was transferring files from an NTFS volume using a high-
speed USB3 Samsung disk.
The transfer rate according to iostat would not go above 900kB/s (yes,
that's not even 1mB/s). The rates for the high speed device should be
over 90mB/s!
A couple of days ago I was using a plain USB memory stick and the
transfers were even worse. It mostly never got over that same rate as
the earlier device.
Running xubuntu 12.04 (output of lsb_release):
Description: Ubuntu 12.04 LTS
Release: 12.04
Some syslog logs when mounting the devices:
