So as I understand Casper can provide big data storage on the blockchain and providers can also choose between Ethereum and NEO. Sounds pretty cool.
yes your right big capacity of storage and can divided large storage is more important also in business world. but also we need to prove that the storage have a strong security that can protect that why casper can provide it.
Protection will be powerful, based on the blockade.
Access only by the code that you yourself will generate.
As far as I understand, security is impeccable.
