When thinking about ZFS or Geom (or even vinum!) and a decent SATA card in JBOD mode: What happens with the write caching? Do the caches only work when you build an array? If they also work in JBOD mode, then I guess it is important to disable all write caching (can you even do that with these cards?) unless you also buy the BBU? I'd be interested to know for sure so I know if I must shell out for a BBU as well as the card itself.... -D
