If a HDD was an Airplane...

S3 is cool on twitter again so here's a slide from my favorite S3 talk by @andywarfield comparing an HDD head to a 747. If the plane was "reading" each blade of grass, it would only miss one blade for every 25,000 times the plane circled the earth: youtube.com/watch?v=sc3J4M…
SCALE AND THE PHYSICS OF STORAGE
If a HDD was an Airplane...
If a hard drive head was a 747 flying over a grassy field...
It would be flying at 75 mph with an air gap of 2 sheets of paper between the bottom of the plane and the top of the grass.
If the bits on the disk were blades of grass, the track width would be 4.6 blades of grass wide and the bit length would be 1 blade of grass.
As the plane flew over the grass it would be counting blades of grass and only miss one blade for every 25 thousand times the plane circled the earth.
