if i wasn't clear enough then i would it like that (with UFS), and 
assuming disks are named disk0....disk48, and that i have at least one 
more disk for system code, often acessed data etc (SSD would be fine), 
while these 48 disks store user/whatever data.

gmirror label ...options... mirror1 /dev/disk0 /dev/disk1
gmirror label ...options... mirror2 /dev/disk2 /dev/disk3
.
.
.
gmirror label ...options... mirror24 /dev/disk46 /dev/disk47

then newfs etc.. and mounted as 24 filesystems. eg. /home1.../home24

then decide how to spread things properly. this depend of your needs.
