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's memory capacity is not definitively known, but it is estimated to be around 2.5 petabytes (or 2.5 million gigabytes). This estimate is based on the total number of neurons and synapses in the brain. However, it is important to note that the brain's storage and retrieval of memories is complex and not fully understood.
Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain's memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes). For comparison, if your brain worked like a digital video recorder in a television, 2.5 petabytes would be enough to hold three million hours of TV shows.
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.
The average human brain is composed of about 75-80% water. This high water content helps cushion and protect the brain, as well as facilitate the transport of nutrients and waste products.

The human brain can store a vast amount of information, estimated to be the equivalent of about 2.5 petabytes of data. However, the exact capacity of the brain's memory is not definitively known, as it can vary based on individual differences and other factors.
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.
The brain doesn't store information like a computer does. While the capacity of the brain is vast and it continuously forms and strengthens connections between neurons to store memories, it's not a finite "storage space" in the way that a computer hard drive is. The brain's storage capacity is virtually limitless and continuously changes based on experiences and learning.
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.
