Ah, thank you so much for noticing this! this is a very important piece of feedback (we will fix it shortly). What we meant was the 10TB is the first tier of the enterprise plans, and the rest are more custom-billed (typically because those also require other custom integrations, etc).
If you find any other points of confusion, please send them our way, and we will fix it, the community has been instrumental over the years in iterating on the product! :)
