PS3 Should I go to NoBD cfw when optical drive only reads CD/DVD ?

Hello.
I have got a backward compatible 60GB model. (CFW since 2012). A few months back it stopped reading blu-ray disc. But reads CD/DVD well. I was thinking to remove the optical drive completely. (to increase airflow)

If I switch to NoBD cfw now, will I be able to change a new optical drive in future?

Do I need to backup something or I can just go to NoBD fw, then back to normal CFW and put in a new optical drive?

For now I am not interested in buying a new drive.

Thanks for you advice!
