Jacek, 

When you say you are seeing "corruption", what do you mean? In my
experience SD card failures typically show as write or read failures,
but not data corruption. 

Like Thomas, I have PI systems that have been running for over two years
with no SD card failures. As long as you don't do something like enable
a swap partition and run so much on the PI that you cause swapping,
there shouldn't be enough data activity to hit any of the SD write
limits for several years.
