Block storage

What is block storage?

Block storage— is a type of IT architecture in which data is stored as a file system. The block storage model stores data files in volumes on a NAS (network attached storage) / SAN (storage area network). Developers prefer block storage for computing applications where fast, efficient and reliable data transfer is required.

Main characteristics of block storage

  1. Scalability: Block storage is easily scalable, allowing you to increase storage capacity as needed.
  2.  Performance: Typically provides high input/output (I/O) performance, making it suitable for mission-critical applications.
  3.  Flexibility: Supports a variety of file systems and can be used as a base layer for many other storage technologies, such as virtual machines.
  4. Use in applications: Block storage is widely used in database systems, virtualization, web services, and other mission-critical applications.

What is the difference between block storage and object storage?

In block storage, files are partitioned and placed in fixed-size blocks. Each block has a location identifier that organizes access through the SAN storage network.

Object storage stores unstructured data. Files here do not use hierarchy and are stored as objects, each with its own identifier. Here you can directly access the data.

When you should choose block storage

  • When you need high performance and fast system response.
  • When you need to flexibly manage storage space and file systems.
  • When you are working with databases or highly loaded applications.
