In my opinion the best thing afs offers to anyone regardless of your 
data needs (sizewise) is the flexibility the system admin has over the 
data. With afs you can move a volume from server a to server b with one 
command. During this time the user is completely unaware. The user can 
read and write to the volume while the operation is in progress.
So if you need to reboot a server or otherwise take it off line you can 
empty the file server and then do with it what you will.  The quota of 
the volume can be increased or decreased as well.
I would suggest giving some thought to your data storage. It isn't much 
use to make a 30 gig volume if you cant move it to another server with 
30 gig space. So similar sized storage media are a good idea.
