Another poster (sorry, could find the name, was it Peter?) mentioned the 
lack of hot-swap support in most of the hardware raid out there. If this 
is the case, what's the point of raid 1 or 5 if a failed drive will hang 
the system? What's your experience with the 3Ware cards?

Okay, okay, you win! You're right and I'm wrong! I will never consider 
IEEE-1394 again. You and the other posters have convinced me. Every USB 
cable in my server room will be removed and destroyed. Every USB port 
will be filled with glue.  :)

What about LVM snapshots? I've been using these for awhile with no 
problems. Yes, I understand that it will consume disk bandwith but 
that's not a limitation in my installation.
