Two differences between XFS and other filesystems on Linux is that XFS

 a) Access the first and last block on the volume during mount
 b) Do some 512 byte reads and writes and some larger 512 byte
    aligned writes.

However, there should be nothing in what XFS does that any self
respecting disk driver/hardware combo should not support - provided
it provides 512 byte sector aligned access.
