> 16 million terablocks, or 8 billion terabytes.

To be clear, the first quote was talking about 2^64 bytes, and you're talking about 2^64 blocks.

Edit: Though confusingly the second part talked about 2^128 blocks.

Also these days I'd assume 4KB blocks instead of 512 bytes.

That's 16 exabytes. Wikipedia cites a re:invent video to say that Amazon S3 has "100s of exabytes" in it.

So it not only could theoretically be done, but has been done.
