   Yes, there is a tiny blue LED that blinks fast with activity. It is hard   
   to see. I mentioned in another post how to make it blink to identify a disk.

   Yes, that's a different model of box, more expensive. I intentionally   
   did not buy that one because I prefer software raid.

   No, my box has no modes, it is just separate disks. I will do a software   
   raid 6 on that. This means it will be slow.
