There's nothing wrong with UFS+SUJ. FreeBSD is awesome for a lot more reasons than just ZFS, and it works well in low memory environments (assuming that you're willing to tweak the kernel/installation a little bit---for example, see https://www.freebsd.org/doc/en/articles/nanobsd/index.html https://www.freebsd.org/doc/en/articles/nanobsd/index.html). That said, the smallest current generation instance from Amazon comes with 1 GB RAM, which is more than enough memory to experiment with everything FreeBSD has to offer.
