* available data space decreased by 3GiB, usable roughly (50 - 3) + (100 - 3) = 144 GiB
* metadata redundancy increased

IOW, the unequal device sizes allow for combined space for data yet improved
redundancy for metadata. If we decide to increase redundancy of data as well,
we're going to lose 50GiB of the second device for obvious reasons.
