Hi John, Take a look on this : https://btrfs.wiki.kernel.org/index.php/FAQ#Is_Btrfs_optimized_for_SSD.3F By the way, on my laptop, I have just one SSD, and I use btrfs on root with /tmp and /var/log on tmpfs (RAM) to avoid simultaneous multiples write on SSD. I never switch off my laptop, I put it in standby or Hibernate mode... so I never loss any logs...
For me and my use, it is the best way to take care of my SSD.
