Just need 3 to make a brain
Within the last year, I read an article speculating when 5TB drives should hit... and the article obviously dove into what needs that much storage...
To illustrate the capacity, it compared it to a human brain - which apparently is estimated to be about 10 terabytes.
It makes you think - sure, the brain is not a perfect recall, but think how much imagery *is* stored in your brain -- you can recognize beyond countless pictures, people, landscapes, etc. Enough to "know" if something has changed. You can recall extensive details about movies, etc. Pretty cool.
Now I want an SD slot in the back of my head so I can store photos directly from my eyeballs :)
