Interesting. I always use f2fs on my ssds, but it does seem to have a
large overhead, so although I think I once used it on an sdhc card for
exactly the reasons you describe, I usually go to ext4 without a
journal to get more space. sdhc flash memory is extremely expensive
so there is a strong motive to maximize the available space.

Aside: I have almost ceased to use USB sticks (apart from booting
live images) because a cheap SSD is far faster and cheaper: I
use usb-sata cables, and they only cost a £ or two. I do use
f2fs also on my heritage USB sticks.
