Even if ZFS would be the only filesystem in existence i would make one per 
2 disks (single mirror).

No matter what's going on, what do you prefer in case say - double disk 
failure from one mirror on 48 disk systems?

losing completely data of 1/24 of users (and then restoring that amount 
from backups), or losing randomly chosen 1/24 of files from whole system?

answer yourself.

With UFS of  course i would have single disk fsck time - less than a hour. which CAN be done 
out of work hours with soft updates.

i normally turn off automatic fsck for large data filesystems, and if 
crash happened i run it after/before work hours.
