FAQ
What is YB and why would I ever care about it?
YB means yottabyte (10^24 bytes). It is mostly a planning unit. To build intuition: one yottabyte is one million exabytes.
How does this relate to big-company storage numbers?
Public discussions about Meta/Facebook-scale datasets are often in exabytes, not yottabytes. Hyperscale environments like Google operate many exabyte-scale systems, while YB remains a much larger aggregate planning order of magnitude.
