Just vague curiosity. Imagine you have a semi-trailer full of DVDs – that’s got to be in the tens of thousands, maybe even the hundreds of thousands if you fill it to the brim. Each DVD holds 4.7 GB, so we’re talking about what, half a petabyte or so? Am I way off here? Let’s assume there’s no cardboard or jewel cases.
At 60 MPH, a semi is going 88 feet per second. If the trailer is, for convenience’s sake, 44 feet long, it gets all that data past a specific point in half a second.
Is there ANY data cable, fiber optic or otherwise, capable of transmitting a petabyte per second?
The speed of the truck going past a point is not really a useful way to quantify bandwidth here. It is more important to use the time from loading the truck until it is unloaded at the destination. The truck probably still wins but that is answering the more important question how long does it take to deliver X amount of bits.
If you allow for many more hours loading, unloading, and unpacking, the contest isn’t hugely lopsided for the truck versus the fastest lines. The truck would win easily for now but there is promise that it may not be that way in 20 years.
And, really, you should consider the time spend burning and ripping those DVDs as well. Moving a pile of plastic from one warehouse to another only qualifies as “data transfer” using the loosest of definitions.
