Block Storage v/s Object Storage:

---------------------------------

1. Block Storage is suitable for transactional databases,random read/write load and structured database storage.
2. Block storage divides the data to be stored in every sized blocks(data chunk) for instance a file can be split into evenly sized blocks before it is stored.
3. Data blocks stored in block storage would not contain Metadata(data created,data modified,content type etc.)
4. Block storage only keeps the address(Index) where the data blocks are stored. It does not store what is in that block, just how to retrieve it when required.
