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.
