Outstanding Features & Performances

Outstanding Performances

Block Storage is fully backed by SSDs for both classes. These high-speed drives allow us to guarantee 5,000 IOPS and 10,000 IOPS with the SSD+ offer coming soon.

Ultra-Secure Replication

Data is replicated 3 times to ensure integrity. Your volumes are highly available and remain accessible even in case of a disk failure.

Easy Setup

Create a Block Storage Volume in few seconds using a CLI or a DevOps tool like Terraform from the Scaleway console.

Hot Plug

No need to reboot your instance to attach or detach a Block Storage volume. Once you’ve added volume, just format and mount to use it

Hot Scaling

Block Storage volumes are flexible. They can be scaled up at any time to increase your available storage space up to 10 TB.

Easy Migration

Easily move your data from one instance to another by detaching and then reattaching your volumes without any downtime.


Backup your Block Storage volumes at any time from the console or by using the API to duplicate them or keep a point-in-time copy in case of an incident.

24/7 Ticket Support

We ensure your services are always up and running. Our technical assistance is available 24 hours a day, 7 days a week to answer all your questions and to assist you. Simply open a new ticket in case of a problem. You can also reach our support directly by phone or to get faster responses if you upgrade your support plan.

Proven Use Cases for Block Storage

Persistent Volumes

Save data after instance or cluster deletion. Kubernetes Kapsule automatically uses Block Storage when you create persistent volumes.

High-Performance Databases

As databases require a lot of IOPS, Block Storage is perfect for storing them. You can also increase your volumes as your project grows with hot resize.

Additional Storage

Expand the storage space available on your instances when your local volumes are nearly full. Each volume is then accessible as a local drive.

Use Block Storage with Scaleway Products

Frequently Asked Questions

Why should I use Block Storage instead of a local storage?

The size of local storage depends on your instance type. With today’s configurations, the maximum local storage available is 600 GB. Block Storage allows you to create bigger volumes and those volumes are persistent which means that they can live without being attached to an instance. Discover the comparison table between local storage and Block Storage.

What are the performances expected from a block volume?

Block Storage offers 5,000 input/output operations per second (IOPS) through powerful SSDs. This guarantees 99.99 % availability to all our customers. However, this performance is subject to fluctuation during peak load periods.

What is the behavior of the block volume when an instance is stopped, deleted or crashed?

A block volume is persistent which means that it can live without being attached to an Instance. Nevertheless, when an instance is deleted, the following can be expected:

  1. When the instance is deleted via the Scaleway console, you will be asked if you want the distant block volumes to be deleted as well or not.
  2. When the instance is deleted via API, all the attached volumes are deleted as well which include the block volumes.

How many volumes can be attached?

A virtual instance can bear up to 16 volumes, including the mandatory local volume. Therefore, the maximum number of blocks that can be attached to an instance is 15.

What is the maximum size of a block volume?

The maximum size of a block volume is 10 TB.

How is Block Storage fee calculated?

The Block Storage billing scheme is not the same as for Object Storage. You are billed by the hour based on the size of the volume and not the data that is actually stored on it. Just like a local drive, you can select the size of the volume directly from the Scaleway console or the API.
