Moving Linux onto SSD drive (first steps)

My computer has an internal SSD drive which was used by Windows 8 as a cache. I was in doubt what to do with that, in particular because the windows tool seems very difficult to configure.
However, since I stay 99% of my time on Linux, I took the final decision: moving my Debian installation onto the SSD drive.
The drive is not so big: 22GB, 4 of them busy due to a OEM partition; so I have only 18GB available.
The first step is to check how much space your Linux installation requires. In order to do that you can use some tools such as baobab or kdirstat.
Baobab is gtk based and it works well, but it only shows the size of entire folders and not the size of single files.
kdirstat is a kde3 utility. If you have kde4 you can use k4dirstat. I would say it is as good as baobab and shows the size of files too, but I had some troubles in running it outside KDE. I have to retry it and see what happens.
However, from the analysis it seems that my OS takes 11GB of space, which is good because it fits in the SSD (and leave 7GB extra space).

Below you can find some useful links which explain how to configure your OS in order to avoid a huge amount of write on SSD
