"Exabyte Unlocked"
https://www.backblaze.com/blog/exabyte-unlocked/

"We’ve reached 1."

"Or, by another measurement, we’ve reached 1,000,000,000,000,000,000."

"Yes, today, we’re announcing that we are storing 1 exabyte of customer
data."

"What does it all mean? Well. If you ask our engineers, not much.
They’ve already rocketed past this number mentally and are considering
how long it will take to get to a zettabyte
(1,000,000,000,000,000,000,000 bytes)."

That is over 100,000 hard disk drives. Maybe 200,000.
