Other people have described the basic disadvantages, but there is one other
consideration: what if you want to add MORE new disks in the future? If you
have the chance to change the PP size now, then I would recommend setting it
to at least 32MB. That would allow you to use 18GB disks in future. 64MB
would open it up to 32MB disks.
If you go with "-t", that'll be fine and you may not think being limited to
16 disks is a problem. But if you need to do it again in a year or so in
order to add a larger disk that limit is going to start getting awfully
close.
