Your key problem is going to be: Will Sun use SLC or MLC?

Hard to find this info though. I would use any SSD in a mirror assuming there WILL be cells going out over time. This would be true for me with both boot drives and slog devices. You can mirror the log device also for ZFS. I'm not really clear though if the log device is a huge enough win on SSD to warrant all this trouble. Depends on your application. I think if performance were my god I would chase after something like a RAMSAN device instead for logging. RAM-based performance with disk as backing-store. YMMV.
