Here's one for you:

A single-layer DVD apparently holds about 4.7 GB of data. So ten of them 
would hold about 47 GB.

That means that if I burn 10 DVDs and mail them to somebody, and it 
takes 2 days for them to arrive, I have just achieved an average data 
transfer rate of about 1 GB/hour. (About 0.2 MB/sec.)

But hey, why burn 10 DVDs when you can just buy a cheap HD and mail 
that? (I'm guessing at this point the weight starts to become 

takes 2 days for that to turn up, that's around 23 Mbit/sec - 
significantly faster than any possible broadband connection.


rate!

On the other hand, if it takes 4 days to arrive, I just halved the 
transfer rate. And the latency is, of course, abysmal...



I found the following quote on Wikipedia:

"The theoretical capacity of a Boeing 747 filled with Blu-Ray discs is 
595,520,000 Gigabits, resulting in a 37,034.826 Gb/s flight from New 
York to Los Angeles."

Somebody bothered to compute this?!? o_O
