Yeah in the past that was a big deal. With SATA, I can't think of a  
controller that doesn't do hot-swap. Granted, without a hardware RAID  
controller, the OS has to manage all that which can complicate things  
(device names might be askew after a hot-swap, for instance).

Yup, that's the plan (the latter device). The back of the GigE switch  
says it draws 5V/2A which seems a bit excessive. Doing this isn't at  
the top of my list though. Plus, I need to see how this might  
imbalance the rest of the system.

Will do!
