What can be the better alternative for someone who is willing to store data off-chain?

What smart-contract suppose to do is just sign a transaction and perform, while every piece of information needs to be saved off-chain. IPFS is one of the popular distributed storage systems but is there any other platform that Dapps usually pick for storage?

There isn't rights answer to your question, depends on the use case and on the business model.

If you want to adopt a full decentralize ecosystem use a distributed decentralize storage (like ipfs, storj ecc)

If you want to store data offchain use legacy file system :) Database or local system. There isnt a better way but a different model to use data.

Database for caching bypass performance Local storage for security ex app mobile Nosql db for not structured data Elastic stack for analytic And so

  • Yeah, the requirement is such that smart-contract data storage may change over time so everything I would like to store in off-chain. SO that overtime if the contract gets changed then I can easily retrieve the information saved so far. – NinjaMAN Jul 31 '20 at 3:53

To complete the first answer, there is a distributed storage platform, called Swarm (https://swarm.ethereum.org/), that has been specially built to work with Ethereum dApps.
