A question about the human brain?
Answer:
Current estimates of brain capacity range from 1 to 1000 terabytes!
"Robert Birge (Syracuse University) who studies the storage of data in
proteins, estimated in 1996 that the memory capacity of the brain was
between one and ten terabytes, with a most likely value of 3
terabytes. Such estimates are generally based on counting neurons and
assuming each neuron holds 1 bit. Bear in mind that the brain has
better algorithms for compressing certain types of information than
computers do."

"The human brain contains about 50 billion to 200 billion neurons
(nobody knows how many for sure), each of which interfaces with 1,000
to 100,000 other neurons through 100 trillion (10 14) to 10
quadrillion (10 16) synaptic junctions. Each synapse possesses a
variable firing threshold which is reduced as the neuron is repeatedly
activated. If we assume that the firing threshold at each synapse can
assume 256 distinguishable levels, and if we suppose that there are
20,000 shared synapses per neuron (10,000 per neuron), then the total
information storage capacity of the synapses in the cortex would be of
the order of 500 to 1,000 terabytes. (Of course, if the brain's
storage of information takes place at a molecular level, then I would
be afraid to hazard a guess regarding how many bytes can be stored in
the brain. One estimate has placed it at about 3.6 X 10 19 bytes.)"

MM, well I know that a Yottabyte is more capacity than the human brain
I love this question. I actually learned that the average human uses only 2% of their brain capacity. Just imagine what we could do if we could use it all.
Nobody knows for sure, but it is surely in the multiple terabytes.
I have two brains, and would like to answer that, but at the
moment, one brain's lost, and the other went looking for it.%})
