["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

michisteiner, as per http://download.lenovo.com/express/ddfm.html an update to your BIOS is available (2.58). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything?  If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

Title:
  [Lenovo ThinkPad W530] I/O slow down

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Since at least 12.10, symptoms are that as time goes by I/O gets
  slower and slower (primarily if not even only writes rather than
  reads). It can be temporarily cured via /sbin/sysctl -w
  vm.drop_caches=2 and/or /sbin/sysctl -w vm.drop_caches=3 but the
  problem will re-appear again sooner rather than later. The problem
  seems also somewhat proportional on how much RAM is allocated. It does
  not seem to appear with less than 8GB (i.e., i saw it first when
  switching to a 16GB laptop/ThinkPad w530) and is considerably worse
  when allowing all memory compared to, e.g., by using only ~14GB using
  the mem=14000M  boot option.
