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. https://btrfs.wiki.kernel.org/index.php/FAQ#Is_Btrfs_optimized_for_SSD.3F

guess my box is an anomaly. I have tw with btrfs root on ssd and have for at least 5+ years.
Theory and practice are often at odds! Thank $deity for the brave experimentalists. I'm also using btrfs on both ssd and spinning rust, though not as long as you. -- Bob Williams System: Linux 4.4.92-31-default Distro: openSUSE 42.3 (x86_64) Desktop: KDE Frameworks: 5.32.0, Qt: 5.6.2 and Plasma: 5.8.7
