Actually, because of the COW nature of BTRFS, it should be better for
SSD's than stuff like ext4 (which DOES kill SSD's when journaling is
enabled because it ends up doing thousands of read-modify-write cycles
to the same 128k of the disk under just generic usage). Just make
sure that you use the 'ssd' and 'discard' mount options.
