# Block Storage

Block Storage is a type of storage that stores data in blocks and serves as the primary storage for Compute Instances, holding the operating system and software.

To make a comparison with general computing, a Volume is like a disk on a PC, such as a Hard Disk Drive (HDD) or a Solid-State Drive (SSD). It functions as the PC's primary storage and is constantly being read from and written to. Because of this, performance metrics like **IOPS** (Input/Output Operations per Second) and **Throughput** (the number of transactions/requests that can be processed in a given time) are very important. This type of storage requires you to reserve a specific amount of space and its capacity is limited to that reservation, unlike Object Storage, which does not require reservation and offers virtually unlimited space.

## Components

The components of Block Storage consist of:

* **Volume:** The storage unit used with a Compute Instance that is constantly being read and written to. It can be transferred to other projects.
* **Snapshot:** The backup component that saves the state of a Volume. It is used for restoring data or creating new Volumes.
