It also happens with kernel 3.13.2-031302-generic #201402061638 (from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.2-trusty/)

Based on previous comment of Ilya Murav'jov I "solved" it temporally
with powertop.

I disabled powersaving modes of these devices:

PM ejecutable para  dispositivo PCI Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 1
PM ejecutable para  dispositivo PCI Intel Corporation 5 Series/3400 Series Chipset 4 port SATA AHCI Controller

Title:
  Slow SATA performance

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hi

  This issue has been discussed over at
  http://ubuntuforums.org/showthread.php?t=447474, and seems to affect a
  number of us.

  File copy speed is very slow (roughly 5-10MBps) on SATA hard drives.
  Copying within the same physical drive is just as slow as copying to
  another physical drive. The issue occurs with GUI tools (Nautilus,
  Krusader) as well as at the terminal using the CP command. This has
  occured since upgrading to Feisty; Edgy was fine.
