I am thinking I will not have much I/O traffic on the SSD hopefully
extending its lifespan.  If it dies I will just need to reinstall
Centos on a replacement SSD.  My critical files will be in /vz that I
need backup on and I think RAID1 will give me double read speed on
that array.  Trying to balance cost/performance/redundancy here.
