Different versions of Linux file systems provide better protection than others.

Personally, I believe that forced write = ON is necessary for all OS -- but I suspect that I am in the minority (some will swear they have never had a problem/db corruption, but I am too chicken to take the risk -- I like sleeping at night).

There is no universally true answer, it depends.

As long as you have the RAM there is no problem.
