If that's really what you want to do then here are a couple more tips. You 
can't boot from a gstripe volume, and when (not if) one of your drives goes 
bad you'll be happier if you only lose your data and not your entire OS. So 
plan to partition the drives and use gmirror for the base OS (since you can 
boot from a gmirror volume). Make a relatively small partition (10GB?) at the 
beginning of each drive. Make a gmirror volume using two or three of them and 
install the OS to that volume. Use the remaining one or two small partitions 
for swap or utility partitions. Then make your giant gstripe volume out of 
the large partitions on all four drives.
