Well, that's a decision you will have to make for yourself. The rationale behind it is to find latent read errors and correct them while you have parity already. Another term for this is "data scrubbing", you'll find quite a lot of discussion on that topic.
Personally, my view is that I make sure all my data are read at least once a month, I have experienced data loss historically because of lack of scrubbing.
