Answer must be in the form of "X Mass of Blue Whale's SD cards holding Y Library of Congress' worth of Data, transmitted across Z Football Field Lengths per second *."
*
unless there's a better measurement of time? Q Length of "Hey Judes"?

@flabdablet You run into weight limits first anyway - at 165mm³ (source each I arrive at 30 kg/l. Checking a rental site indicates a Ford Connect will fit 2.8³ of cargo, but only 667kg. So we hit the weight limit at only 22l of SD cards. The larger Ford Transit will fit 3.6 m³, and goes up to 933kg (or 31l of SD cards).
A weight-first calculation gives me 2000 cards per kilogram, or 1 petabyte per kilogram. You won't hit an exabyte (1 tonne of cargo) in any normal passenger car.
...I will absolutely concede, especially with my Imperial Units educational impediment, that I am likely wrong...but I think it is 3kg/l?
Google agrees, I must have mispositioned the decimal point. Does seem like a more sensible number. You still run into the weight limit first with both sample vans, and the 2k cards per kilogram number I derived separately from 0.5g per card and I'm pretty sure I did at least that one right.

Really?
Windows Disk Manager
also fdisk/parted because command line is king.
parted is capable of using SI uinits, but it is NOT the default.
LIES
also
ls
lists size on disk in 2^10 based units instead of 10^3LIES
as do every file manager i have used to date.
something something timepod something... Xfce/Thunar:

Implausible. That would make them denser than osmium.
Checking source: I agree with 165 cubic millimetres for the volume; my wild-ass guess was too low. That means a million cards occupies 165 litres, not 100.
0.5g is listed as an approximate mass, so a million cards would be 500kg. 500kg / 165 litres is 3kg/l, not 30.
-
@flabdablet Yeah, @polygeekery called me out on that as well. My math was off. But that only affects the calculations with the example vans, not the how-much-does-an-exabyte-weigh example.
-
@PleegWat Assuming 256GB cards, an exabyte requires 1018 bytes ÷ (256 * 1012 bytes / card) = 3907 cards. At 0.5g each, that's under 2kg.
@PleegWat said in Skype Call vs. Windows Update:

So if the cargo is denser than 667kg / 2800l = 0.24kg/l (which ours is), then the weight limit is what matters.
667kg ÷ 0.5g/card * 256GB/card * 8 b/B comes to 2.7Zb; at 1.5ks coast to coast, our final data transfer rate is 18.5Eb/s.
Which isn't as exciting as 68, but still not too shabby.
-
@flabdablet Last I checked, a gigabyte is 10⁹ bytes.
EDIT: also, in what car do you drive coast-to-coast in half an hour?
-
@PleegWat Fucking decimals, how do they work.
Take 2:
@PleegWat Assuming 256GB cards, an exabyte requires 1018 bytes ÷ 256 * 109 bytes / card = 3906250 cards. At 0.5g each, that's a bit under 2 tonnes.

So if the cargo is denser than 667kg / 2800l = 0.24kg/l (which ours is), then the weight limit is what matters.
667kg/wagon ÷ 0.5g/card * 256GB/card * 8b/B comes to 2.7Eb/wagon; at 150ks coast to coast, our final data transfer rate is 18Tb/s/wagon. Which isn't as exciting as 68, but still not too shabby.
If we use 512GB cards and fill the road with wagons maintaining a safe following distance of two seconds, we can stream at 2.8Eb/s with under five seconds of buffering.
The resolution of the video display required to saturate this link is left as an exercise for the reader.

Is that a kilosecond? A cromulent unit, but unusual.
