Look... if you want to get a real speedup in I/O on the same hardware  
without getting a SSD, you should grab yourself a recent dovecot  
version (2.2.X), enable gzip compression and switch over to mdbox.

Maildir is fine as long as you don't have too much mail on your  
storage, but there comes a point when you are getting big enough where  
Maildir really isn't going to behave really nicely anymore, because  
too many files and way too many seeks. Mdbox is quite different and  
scales beyond the point of Maildir with ease.
