Thanks that is a bit more enlightening. I'll read the given link and other source today, to get more into. Especially if it helps avoiding writes to SSD, as I got burned very hard from wearing down SSD (it was a software bug that lead to it). I guess the performance difference and the amount it saves from SSD rewrites shouldn't be too much to be worried about, but it bugged me so much that I will take this into consideration nonetheless.

Guess I learned something new today. :-)
