If you use btrfs, double it.

Never use BTRFS on an SSD. Even the BTRFS devs don't recommend it.
They use to flat out say don't do it.

Now after 4.14+ they just say its not optimized, and won't trim properly.

see also in depth explanation:

does this mean we have to remove the "ssd" option on btrfs system and is it possible without harm?

thanks
