What is infinite storage?
A colleague of mine, a Ph.D. in Physics, objected to my use of the term “infinite storage” in some lecture notes I posted on the Web.
I think that infinite storage is something that might be possible in my lifetime. What does “infinite storage” means? Let us consider how much is required to achieve the mythical (digital) memex.
- To record everything you read in a year requires 25MB.
- To record everything you hear in a year requires 100GB.
- To record everything you see in a year requires 10TB.
Hence, I argue that whenever I will be able to buy a cheap 10TB disk at my local electronics store, I will have infinite storage. Currently a portable 1TB drive can be had for $569.
What about recording everything I hear? Right now, I can buy a slick 100GB portable drive for $160. Interesting question: how would I ever search through all these sounds? And what about all these people who will get upset that I am recording them?
