Ceph issues fsync's all the time
...and, of course, it has journaling :) (only fsync is of course not sufficient)
with enterprise SSDs which have capacitors fsync just becomes a no-op and thus transactional write performance becomes the same as non-transactional (i.e. 10+ times faster for 4k random writes)
