This nice-time is configurable via kern.geom.raid5.veri_nice (value is in ms and must be in this range: 0..999 (or else it is ignored)). A graid5 out of 2 disks behaves like gmirror with 2 disks and balance read-strategy. But graid5 is still experimental (not so many stress tests) and if install instructions are not so easy, because u have to go into /sys/modules/geom/geom_raid5 and /usr/src/sbin/geom/class/raid5 and do a "make && make install" there)...
