[Dovecot] Dovecot and SSD

I'm considering setting up my own mailserver with Dovecot 2.0 (as soon
as it's out) and SSD. I'm debating whether it's worth it or not. I
have been running a mailserver with the Dovecot 1.1 train for a couple
of years and it's been flawless and amazing. I'm thinking about using
either FreeBSD 8.1 w/ZFS or OpenBSD 4.8-beta on a 64 GB or 80 GB SSD
(Corsair or Intel) using Dovecot 2.0 and mdbox. It seems like mdbox
would benefit the most from an SSD because reads would be extremely
fast while minimal writes (comparatively) take place due to the way
mdbox is structured. I guess what I'm saying is that even if the SSD
has average to slow write speeds the fast read speeds would make a big
difference in many operations. Any thoughts? Alternately, run either
option on a hard drive with indexes on fast flash memory. Anyone tried
something like that? Thank you.
