As mentioned in an article in Scientific American, the memory capacity of a human brain was testified to have equal to 2.5 petabytes of memory capacity. A “petabyte” means 1024 terabytes or a million gigabytes so that the average adult human brain can accumulate the equivalent of 2.5 million gigabytes of memory.
Most computational neuroscientists tend to estimate human storage capacity somewhere between 10 terabytes and 100 terabytes, though the full spectrum of guesses ranges from 1 terabyte to 2.5 petabytes.
The average adult human brain's memory capacity is 2.5 million gigabytes. However, it doesn't run out of storage capacity, per se. A single human brain has many different kinds of memories. And there's no physical limit to the number of memories we can store.
The human brain has a capacity that is ten times greater than first thought and can retain 4.7 billion books, scientists have discovered. This is according to US scientists who have measured the storage capacity of synapses - the brain connections that are responsible for storing memories.
The long-term memory does not remain stored permanently in the hippocampus. These long-term memories are important and having them stored in only one brain location is risky – damage to that area would result in the loss of all of our memories.

Homo neanderthalensis has the highest brain capacity of around 1400-1500cc. Homo sapiens has slightly lower capacity of around 1300cc. Homo erectus has 900cc brain capacity.
But since then, human brains have actually shrunk slightly. The lost volume, on average, would be roughly equivalent to that of four ping pong balls, says Jeremy DeSilva, an anthropologist at Dartmouth College in the US.
The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms). Larger brains don't necessarily make a smarter mammal. But as mammals evolved, many groups, from Primates to Carnivora, have shown independent increases in brain size.
The simple answer to this question would be, “no, your brain cannot run out of memory”. However, there must be a physical limit to how many memories we can store. Despite our limitations, they are extremely large. So, you don't have to worry about running out of space in our lifetime.
Let's start with some good news: The idea that your brain can be “full” is a myth. We know that a brain is never too full to learn more, and cannot be filled to capacity.
The deadpan answer to this question would be, “No, your brain is almost certainly not full.” Although there must be a physical limit to how many memories we can store, it is extremely large. We don't have to worry about running out of space in our lifetime.
BRAIN FOCUS & CONCENTRATION FACTS & STATISTICS
The human brain is able to focus up to two hours, after which it needs a 20-30 minute break. The average American spends about 9 hours a day at work. According to the NeuroLeadership Institute, work focus equals about 6 hours a week.
A terabyte is one of the largest units of storage media that products on the market use today, but it is not the biggest unit of measurement in data storage. Units larger than a terabyte include a petabyte, exabyte, zettabyte, yottabyte and brontobyte.
As a number, a “petabyte” means 1024 terabytes or a million gigabytes, so the average adult human brain has the ability to store the equivalent of 2.5 million gigabytes digital memory.
According to the “cultural brain hypothesis,” humans evolved large brains and great intelligence in order to keep up with our complex social groups. We've always been a social species, and we may have developed our intelligence in part to maintain those relationships and function successfully in these environments.
Broadly speaking, evolution simply means the gradual change in the genetics of a population over time. From that standpoint, human beings are constantly evolving and will continue to do so long as we continue to successfully reproduce.
The result is that we can see which traits have changed in the past 2,000 to 3,000 years. They are hair color, height, lactose tolerance and insulin levels, infant head circumference and birth weight, and decreased BMI in males.
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
The preponderance of the cerebral cortex (which, with its supporting structures, makes up approximately 80 percent of the brain's total volume) is actually a recent development in the course of evolution.
Severe stress, depression, a vitamin B12 deficiency, too little or too much sleep, some prescription drugs and infections can all play a role. Even if those factors don't explain your memory lapses, you don't need to simply resign yourself to memory loss as you age.
After reading, you may find it almost impossible to retain the information acquired. It may be due to lack of adequate sleep and rest, distractions while reading, poor nutrition, failure to choose the right book, or memory issues such as decay or shallow processing.
Although you can't erase another person's memory, you may be able to distract them from the event, communicate openly, or admit to mistakes. Trying to distract someone or apologize for a challenging behavior may not remove memories or the impact of your actions, but it might help you both move forward.
