I did mention that putting a hard drive on an AVR does not make sense?
It may be possible, but why bother? A server should have more RAM than the controller board!
Ok, I don't get it. How do you do that ? [Arduino]<===>[server]
Can you show a block diagram that includes all the required components between the two ?
I assume the idea you are describing revolves around an Ethernet Shield . Is that correct ? (or are there other components rquired ?)
