I was reading the Selfish Gene and I got to the part where the autor says that the human brain stores data much more efficiently and has a much more complex retrieval mechanism of memories than a computer counterpart. If storage and access are the goals, wouldn’t a “smooth” brain make more sense?

Its a logistical problem.
What limits the brain is not how much brain cells you can pack into your head, but how you can feed all those cells.
The brain cells get nutrients from blood, but blood cant flow freely into the brain – its absorbed via the surface of the brain. Thus, the larger the surface, the more nutrients can be absorbed, and the more braincells you can have.
If your brain was a smooth ball, the cells further inside would simply starve (and die from their own excretions, which wouldnt be properly removed).
