Does ExperimentalStableMemory have the same cost as runtime memory?

https://internetcomputer.org/docs/current/developer-docs/gas-cost
Here it says about the price: “The cost of storing 1 GB of data is about $5 per year”,
Is there a difference in storage cost between ExperimentalStableMemory and runtime memory, ExperimentalStableMemory looks more like a hard disk, it will be cheaper?

No, there is no difference for now. And I’m not aware of any discussions on changing that

Okay, I understand

Thank you!
