Writing filesystem blocks won't help. RAIDframe needs writes as large
as a stripe.
The log itself could write much larger chunks but flushing is done
in a series of writes as small as a single physical block. I think
the only way to improve that is to copy everything first into a
large buffer. Not very efficient.
