Currently Filecoin is priced at 0.02% the cost of Amazon S3 to store data (you can view all the stats https://file.app/). Specifically, the price is ~$0.0000025 USD per GiB per month.
The stats you mentioned above is the block reward subsidy that the network provides for Filecoin Storage Providers (similar to how Bitcoin miners earn bitcoin for mining), so the incentive for Storage Providers is to charge clients as little as possible so they can store real data, and earn the associated block rewards.
