How Much Data Can Each Storage Device Hold? Bit to Zettabytes

How much data can different storage devices hold? From a single bit of magnetic memory to theoretical DNA storage measured in zettabytes, this video explores the evolution of storage capacity from tiny amounts to massive data-storage systems.

In this video, we compare 46 storage capacities, including magnetic core memory, punch cards, magnetic drums, floppy disks, Zip disks, CDs, USB flash drives, SD cards, DVDs, Blu-ray discs, SSDs, HDDs, LTO tapes, enterprise storage, tape libraries, data centers, and theoretical DNA storage.

Watch the complete journey of storage capacity — from 1 bit → kilobytes → megabytes → gigabytes → terabytes → petabytes → exabytes → zettabytes.

This video is created for educational and informational purposes. Some capacities represent historical formats, specific products, maximum capacities, or theoretical storage potential rather than typical consumer devices.
