How much data can a semi-trailer hold?
Posted by tim in I am BORED! on November 23, 2004

I got a random thought earlier:

If DVD's were to be stacked side-by-side and on top of each other in a typical semi-trailer, how much data would the trailer actually hold?

To keep it simple, I am going to use single layer DVD's, which hold about 4.7GB.

I used estimates on the size of the trailer. Width: 8' 6" Height: 9' Length: 53'

Now, a standard size CD-R has the following dimensions: Diameter: 4.687" Thickness: .062"

I figured that the space occupied by each disk would be a cubic area with the dimensions below: Width: 4.687" Height: .062" Length: 4.687"

According to my calculations, approximately 21 disks will occupy the width of the trailer, 135 will occupy the length, and 1741 will occupy the height. This figures out to a total count of 4,935,735 disks in the entire trailer.

Now, since we're working with single layer DVD's, we need to multiply this county by 4.7GB: 21,223,660.5 GB

That works out to 21,223.66 TB, which works out to 21.22 PB. That's about 1/2 as much data as the entire KaZaA network holds!


(22:11:20) Josh: How about I tell everyone that you thought of this while taking a leak? >:P (22:11:31) Tim: actually, it was while i was taking a crap (22:11:53) Josh: Oh. Ahem. Well... (22:12:43) Josh: I just assumed it was while you were taking a leak... That's where some of my more crazy ideas come from. Duty #2 is reserved for philosophical pondering.

Depending on the data, you could compress it all first -- then the trailer would hold a bunch more.

Or you could use a different media. I thought about figuring it for 200GB hard drives. :)

For those intersted, I calculated the volume for a standard 250GB hard disk. That comes out to approxamately 71850.585 TB (71.8505 PB) or, currently, 1.55672 times the data on the KaZaA network. Now for those truly interested: at the cost of $132 (the current lowest price for a 250GB hdd on pricewatch), that would come out to somewhere around $38,847,600 total.
