I have developed a storage Infura called ICDA, and you can refer to the project introduction at Project Introduction.
It is currently in the MVP version, with main features including K-V storage and the generation of storage proofs for the stored data (which can be understood as a Merkle Tree plus Signature).
I have already stored more than 20G of data, and ICDA is performing very well.
Are you interested in using my solution?
