If you are considering using it as a conventional filesystem from a few

filesystem designed to be consumed in a massively distributed fashion,
so it does fall into its own category.

run work near the job.
I'd compare with GFS and Amazon S3 rather than NAS/SAN systems, which
are normally trying to hide the fact there is networked storage underneath
