Is this the best way to go?  Much of the recent mail software, postfix,
dovecot etc has features which make it easier to set up redundant
mailservers and distribute the load across them.  This will scale better
if your needs grow down the road.  SSD's tend to be rather costly,
especially if your storage needs are high.   I guess the main advantage
to a single server with SSD is lower power consumption.

What about RAID10?
