	The life of an SSD is pretty much determined by how often you write
to it.

	I'm doing something similar with a 40GB Silicon Power V20. I
have /var, /tmp, /home. /usr/obj and /usr/pkgobj ($WRKOBJDIR) mounted from
hammer PFS on RAID1 HDDs (there are a couple of storage PFSs as well) with
everything else (system, pkgrsc, distfiles) in an 8GB UFS partition on the
SSD (currently using 3.1G - I only have a very few packages on this box
though, if I had more I'd want a bigger partition on the SSD - there's
plenty of space).

	The aim being to put the rapidly changing stuff on HDDs and the
frequently used slow changing stuff on the SSD (along with swapcache which
has a 16GB swap partition to play in).
