Title:
  USB IO excruciatingly slow on NTFS with dell xps15 laptop

Status in “ntfs-3g” package in Ubuntu:
  Confirmed

Bug description:
  (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:

  The high speed drive reported:
