The source that (mistaken) claim (http://en.wikipedia.org/wiki/Deep_Web#cite_note-2) is based on disagrees:
That says it was 20 TB, not 3000 TB.
Or am I reading this wrong?
That chart didn't include all the audio and video recording files. When you add that, it gets to 3000 TB.
Yeah, that was probably about right.
If it were only 20 TB, it would be theoretically posible to mirror the entire internet in your basement with a few thousand dollars worth of hard drives.
I thought that the internet was being measured in petabytes now.
“Estimating that is a fairly difficult task, but one person made an estimate not so long ago who can probably be trusted to have a good idea. Eric Schmidt, the CEO of Google, the worlds largest index of the Internet, estimated the size at roughly 5 million terabytes of data. Thats over 5 billion gigabytes of data, or 5 trillion megabytes. Schmidt further noted that in its seven years of operations, Google has indexed roughly 200 terabytes of that, or .004% of the total size.”
