How much could you cram on to an 8" floppy?

It can be very useful for cloud services.

According to IBM, by the time we reach 2025 the world will be creating 175 zettabytes of data.

Per day? Per year? 320 GB per square inch of tape.

Wonder if something like backblaze might transition to tape vs HDDs.

Tape still has the age-old problem that it is sequential not direct access.

some cloud services use "glacier storage", i.e. cheap long term storage. when you want to access a large file, they need to unfreeze it, which can take several hours pr perhaps a day. I know that since I work with many large files hosted in the cloud. up to 20 GB are considered small files, LOL

There are tape formats that are not completely sequential. An index is written that allows the drive to fast forward to the right area of the tape and the correct track. Not random access but faster than sequential alone.

Anyways people have been forecasting the demise of tape for decades. But they keep increasing the capacity and the format is much easier to store and transport than some of the alternatives.

I bet it takes four weeks to write the whole tape back to a RAID array.

Try CERN.
Over 90 petabytes of raw data per year. Processed in a global distributed computing system with tens of thousands of researchers and analysts (And you can analyze some of the data yourself).
