There are general well-known rules about behaviour of various RAID
levels, which should also hold for ZFS.

What kind of performance? read / write, sequential, scattered? One or
more heavy users (applications)? All users behave the same or some are
sequential and some are scattered?

As a rule of thumb, if you don't know the parameters of disk access,
with this many drives you won't make a big mistake if you put them all
in a single raidz (you should consider purchasing one more drive and
using it as either spare drive or make a raidz2 out of all drives together).
