Block storage is designed for structured data that requires consistent low-latency read/write access and is typically used with a single instance. It is often employed for databases or to provide the file system for servers. Object storage, in contrast, is designed for unstructured data and allows for massive scalability but doesn’t offer the same low-latency and consistent performance as block storage. File storage allows for the sharing of data across multiple instances at the same time which makes it less suitable for the requirements of a traditional database that block storage is more suited for.
