Block Storage is essentially a group of hard drives connected through a fiber-optic network. Object Storage is an ideal choice for applications such as databases that require consistency. Block storage is mainly used for data that is structured. Object storage is ideal for storing multiple types of data such as images, videos, notes, etc. The only drawback to object storage is that you cannot update the data already stored. Data encryption and data sniffing are the most important safeguards in Block Storage systems. Unauthorized access and sniffing can't get much sense of those who steal or destroy data.
