2 gb according to my mate Antony
*Edit* Lol, try something like 2 Terabytes and you are still going to be very far from the truth. I don't think that it is possible (yet) to evaluate the capacity of the human brain. The fact is that a person can remember hundreds of movies, songs, books, events from the past, pictures, faces, names, phone numbers, etc., that if all those memories had to be put on a hard drive, terabytes upon terabytes wouldn't be enough.
A quote from some researchers.
"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.)"

The human brain has a tremendous capacity for storing information. While it is difficult to quantify exactly how much information the brain can hold, it is estimated to have a storage capacity of around 2.5 petabytes (or 2.5 million gigabytes). This is roughly equivalent to 3 million hours of television shows. However, it's important to note that memory storage is a complex process and can vary greatly among individuals.
A human liver typically weighs twice as much as a human brain.
10 pounds for the average human
A Neanderthal brain was around 10-15% larger than a modern human brain, on average.
If you mean "How much percentage of water does a human brain have?", the answer is about 77-78%.

in the short term memory it is able to remember something for up to thirty seconds without rehearsal where as if it is stored in the long term memory it can be stored until it is displaced or 'removed'.
There is no such thing as "brain capacity"
The capacity of the human brain cannot be defined in binary computer units, as the brain does not use binary addressing. As knowledge, feelings, and memories do not have a standard format, it would be impossible to determine how much space it would take to place this data in binary form.
It has a capacity of 1.5 Megabytes of Flash Memory.
Almost the whole entire brain uses storage or memory when it does something. Examples: When we see you may ask yourself the question; how did my brain know that was there? Your brain uses its memory of the world, past experiences, and what it thinks should be there in order to give you vision. When we dream our brain uses memory from our memory storage and mixes non-useful images and ideas together erasing them from our memory, this is why be cant remember all our dreams completely. When we smell our brain uses a its memory in smells and signals the nerves in the nose to smell what we remembered what it smelt like before. Almost everything comes from memory or storage.
You can lose your memory from becoming old or from losing to much white brain cells.
A human liver typically weighs twice as much as a human brain.
The average human brain weighs about 3 pounds (1.4 kilograms).

A computer with 3MB of memory storage capacity can be limited. This will be the size of a single photo taken it cannot be useful in terms of data storage.
