Nah, I'm not too motivated.
For the moment I can write down the bits on my thumbnail.
I optimised my writing enough to fit 2TBon each finger nail.
Read/writespeed is still a little slow, but enough for long term storage.
Hmm.
A fingernail is roughly square, about a centimetre per side, or 100 square millimetres.
A human fingernail grows at roughly 0.1 mm per day
So, assuming you clip your nails, for storage purposes you are losing a rectangle 0.1 mm x 10 mm (on average) every day, which is, conveniently 1 square millimetre.
If the fingernail holds 2 TB, the areal density is 2 TB per 100 square millimetres, which is 2,000 Gigabytes per 100 square millimetres, which is 20 Gigabytes per square millimetre.
To keep up with fingernail growth, you need to rewrite 20 Gigabytes per day.
A day is 86,400 seconds. So that's writing roughly 230 kilobytes per second.
English averages out at roughly 5 letters per word in written text. Add a space or punctuation between words gives a total of six characters per word. If we assume a character mapping of one byte per character, 230 kilobytes per second is about 38,000 words per second.
War and Peace is roughly half a million words in English translation, so you write the rough equivalent of
War and Peace on your fingernail every 13 seconds, just to keep up with nail growth.
I'm seriously impressed. My fingers and wrists would be rather tired and painful. And you actually do better than that as I expect you sleep and eat occasionally.
Confuzzled, in a light-hearted mood.
