There should be no problem in putting /var on the harddisk. I also had a setup
some time ago where /var and /tmp were located on a harddisk while the other
PFS like / and /usr were located on an SSD.

AFAIR there was a thread on the mailing list with some recommendations how to
configure the PFS when it is placed on an SSD. Reblock and rebalance should be
run less frequent than it is configured by default.
