> the extreme amount of volume and limitations of storage space.

Speak for yourself then. I've already got 10TB of storage at home in a case the size of a shoebox. It's got my entire life in it (at least every file I've created since university), but most of it is storing my movie and music collection. So, realistically your entire life can fit in a 1TB drive once you exclude videos and transcode audio. 2-4TB if you're a person of interest.

Do know that 1 Backblaze 4U-server holds 135TB. They are building a datacenter in Utah with 100,000sqft[1] of rackspace. 20,000 racks per floor (I don't know if there are multiple stories) gives you 29.7 petabytes if they used a Backblaze solution.

So yes, if the US govt wanted to record everything you did everyday they are more than capable of doing it, now.

They are sitting on at least an Exabyte. With multiple-Yottabytes of traffic.


You're right, I'm off by a few magnitudes. 29.7 exabytes if they use every square foot for servers JBOD. And that is with current disk tech.
