Did you know we are living in the Zettabyte Era? Honestly, did you even know what a zettabyte is? Kilobytes, gigabytes, maybe even terabytes, sure, but zettabytes? Well, if you ran data centers you’d know, and you’d care because demand for data storage is skyrocketing (all those TikTok videos and Netflix shows add up). Believe it or not, pretty much all of that data is still stored on magnetic tapes, which have served us well for the past sixty some years but at some point, there won’t be enough tapes or enough places to store them to keep up with the data storage needs.

That’s why people are so keen on DNA storage – including me.

A zettabyte, for the record, is one sextillion bytes. A kilobyte is 1000 bytes; a zettabyte is 1000⁷. Between gigabytes and zettabytes, by powers of 1000, come terabytes, petabytes, and exabytes; after zettabyte comes yottabytes. Back in 2016, Cisco announced we were in the Zettabyte Era, with global internet traffic reaching 1.2 zettabytes. We’ll be in the Yottabyte Era before the decade is out.
