Block Storage Vs File Storage Vs Object Storage

Block storage (fastest performance, highest cost, medium scalibility)

Controlling the actual block in HDD or SSD. Give you the low-level control and is very fast

Use case

• Database
• High performance application

Example: AWS EBS

File storage (medium to high performance, highest cost, high scalability)

Abstract layer on top of block storage. to manage file

Use case

• General purposes

Example: AWS EFS

Object storage (Low Cost, Low-medium performance, highly scalable, non-mutable)

Use cold data for archival storage.

Use case

• Archive
• Store big files

Example: S3

[!note]
Object storage can store at a much better capacity because it's a flat file storage system where object just float around everywhere. Using file storage there is a limitation of the file storage structure.

Block storage is too low-level and it might not be optimised
