How to create a Block Storage volume

Reviewed on October 13, 2025

Scaleway Block Storage allows you to easily create volumes to attach to your Instances. Volumes are storage spaces that you can attach to one or several Instances.

Before you start

To complete the actions presented below, you must have:

• A Scaleway account logged into the console
• Owner status or IAM permissions allowing you to perform actions in the intended Organization

1. Click Block Storage in the Storage section of the side menu. The Block Storage page displays.
2. Click + Create volume.
3. Follow the steps in the creation wizard:

   • Choose the same Availability Zone as the Instance you want to attach your block to.

   • Configure the volume:

     • Enter a name for your volume or leave the automatically generated name.
     • Select an IOPS option. You cannot edit the IOPS of a volume after its creation.
     Note

     To use Block Storage 15k, your Instance must have at least 3 GiB/s of block bandwidth. You can verify if an Instance type meets this requirement by consulting the Scaleway Instances internet and Block Storage bandwidth overview documentation.

     Alternatively, use the Instances API to check the block_bandwidth field at /instance/v1/zones/{zone}/products/servers.

     • Define a volume size of at least 5 GB.

   • Optionally, select an Instance from the drop-down to attach your volume.

   • Verify the estimated cost.

4. Click Create volume. The volumes overview page displays.
