Yeah, thumb drives have really gotten enormous over the years. My concern about the above would be, if one drive fails, you have to down the box, or at least slide the case out and open it, in order to change it. I would be slightly more inclined to do this with external drives. Question: does the controller backing the four hot-swap bays support device carving? You can take one RAID array and expose two volumes to the OS, which appear as separate devices. Both 3ware and MegaRAID cards support this; I imagine Areca does too. One downside is that you can't replace the entire RAID5 on the fly, since it has your OS. --keith -- kkeller at wombat.san-francisco.ca.us
