How does STORJ store data?

Can you explain how STORJ stores data in a simple and concise manner? I'm interested in understanding the process behind their decentralized storage system. Does it involve encrypting data before storage? And how do they ensure the security and privacy of user data? Additionally, what kind of redundancy measures do they have in place to prevent data loss? Lastly, what makes STORJ's storage solution unique compared to traditional cloud storage providers?
