What is Block Storage?

Block Storage is a simple, convenient way to add storage space to a server without having to change the server size. You can easily resize a Block Storage volume, remove it, or assign it to a different Servidor Cloud. The storage volume is mounted like an extra hard drive, which means that your applications can target it to store data.

Block Storage offers strong performance advantages over other data storage methods. It is particularly well-suited for databases and other forms of high-speed, high-volume transactional data.

When to Use Shared Storage Instead

One key difference between our Block Storage and Shared Storage products is that Block Storage can only be attached to one server at a time. However, a Shared Storage volume can be used by several servers at the same time.

This means that Shared Storage is the best choice for any project where multiple servers will need access to the storage volume at the same time.

Example Block Storage Use Case: Database Storage

The performance benefits of Block Storage make it an excellent solution for database storage, particularly when high-performance transactional data is in play.

After adding the Block Storage to the server, you will simply need to configure your database to store its data on the Block Storage device.

Because the Block Storage is portable, you can detach it from the initial server and attach it to another. This provides you with an easy, secure way to move the database to a new server.
