How much data/information our brain can store ?

I have been thinking, if the human brain could be theoretically modeled as an artifical neuron network, then how much storage space would it need on a computer.

According to conventional biology, the human brain has an average of 100 billion neurons, and 100 trillion synapse connections.

1,000,000,000,000 (1 trillion) connections:@ 128-bits = 1.28e14 bits
Okay, so lets bring it into the real world

In Terabytes (128-bit): 14901 terabytes
In Pentabytes (128-bit): 14.55 pentabytes

Amount of DVD's it would take to 'make a backup' of someone's brain:
3.2 million DVD's (4.7 gb)
Thats 555 years of DVD quality video :-)
Want to take backup of your brain ?? LOL!!
