Like when you send a .7z instead of a .zip or .rar to a friend or a teacher because that’s what your computer has installed and they’re like “Oh No, not one of those, now I have to install 7Zip” even though the same program that opens .rar also opens .7z I feel like people are way more annoyed when they receive a .7z
Just drive over to their house with a USB drive. Problem solved!
To transfer 1tb of data from London to Edinburgh at 100mbit/s it would take around 22 hours.
To put a 1tb SSD in a rucksack and get the train to Edinburgh drop it off and come back would take about 9 hours.
“Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway”
Lol company I work at unironically has this as a suggestion for securely transfering sensitive data instead of cloud stuff. Although I think it’s more of “please learn how to use our secure server, I’m begging you” thing.
never underestimate the bandwidth of a van full of hard drives
3.5" hard drives have a physical volume of about 0.0107 cubic feet. A Chevy Express has a cargo volume of 239.7 cubic feet. Assuming that only 200 cubic feet can be effectively used, roughly 18,000 hard drives can be loaded into the van. If each hard drive is a 22TB Western Digital (largest mass available to consumers), that’s 396,000TB of data. Let’s assume a travel distance of 2 hours in the van, with an extra 4 hours on each end for unloading/loading. That’s 396000TB per hour/6600TB per minute/110TB per second. Most wireless connections are measured in mega/gigabits (not bytes) per second, so that’s 880Tb per second. This is far faster than any wireless connection available, even with much longer travel and unloading times. We can therefore conclude that a van full of hard drives has very good bandwidth.
*station wagon **tapes
In high school usb drives werent yet a thing so we had a SneakerNet using an Iomega Zip Disk.
