"BTW How many bytes of data can an average human brain hold?"

That's a good question. Just looking at cortical neurons (20 x 10^9) in parallel and the maximum transmission rates of neurons that I have found in the literature (10 bytes/sec) would give you 0.2 terabytes/sec as the maximal bandwidth. In actual fact, it is probably severely limited by several bottlenecks in the system and differential activation of various cortical areas. As we all know, the information stored also degrades over time - sometimes you didn't actually post what you thought you posted a year ago.

I don't know of estimates of actual stored information - which would have similar sever constraints. I would be interested if anybody else has.
