It Would Take 21 of These IBM Hard Drives from 1956 to Hold a Single D800 RAW File
Here's both a neat picture and a mind-blowing fact for you. What you see above is the IBM Model 350 Disk File from 1956. It weighed over a ton, contained fifty 24-inch disks, and was leased to companies for $3,200 per month. It could hold... 3.75 Megabytes.
That means that it would take 21 of these puppies to hold the largest 14-bit RAW file the Nikon D800 spits out.
