There are some other considerations. XFS has a good track record for large
numerical calculations, video production, and remote sensing. These
are applications where the data are lost due to downtime recovering from a
crash are much larger than the data that was "in flight" when the crash
occurred. XFS puts priority on metadata consistency, so filesystems are up
and running very quickly after a crash.
There are applications where losing a few bytes of data should "never"
happen, even it results in substantial downtime.
