I've been wondering about SSD as well. I have about 1000 users many 
which have really large inboxes and I'm using maildir format. SDD has no 
seek time and I wonder if those drive heads are all over the place as 
people do searhes and such. So if anyone does this I'm interested to see 
how it works.
