System Design: Storage

** System Design **
Today, we are going to see the storage concept in system design.
Two types of storage data

1. On Disk

2. In Memory

3. On Disk
   The data which we store on disk will be persistence. It means that the data is still available after the server is down.

4. In Memory
   The data is not persistent here because the data is available as long as the server is up. As soon as the server down, the data removes.

In summary, we can say that three concepts involved in storage.

1. Disk
2. Memory
3. Persistence

We will look in more concepts in future in this series.
Thank You!

Databases are key concept and technology used in every SD interview. DBs are important as part of the Non-Functional Requirements where we do certain calculations on storage and throughput. I have created System Design Template which is generic enough to be used for any interview but also FAANG companies.
