It matters a bit - in case of a single mirror (and all partitions on top
of it) when there is a crash, during disk activity, the whole mirror
will get rebuild. While if there is a separate mirror for each
filesystem the chance is that some filesystems will not be active during
the power failure/crash and thus their mirror will not need to be
rebuild. It is just a matter of speed, not data loss, and it depends on
the usage of the filesystems. Currently I have 2 mirrors and after a
crash just one of them is rebuild because the other one is rarely used.
