Ultra resilience
Your data is replicated three times on multiple nodes to guarantee availability, even in case of a disk failure.
Block Storage
Flexible and reliable storage for demanding workloads.
Flexible vertical scaling
Seamlessly adapt your storage to any changes in your activity by attaching up to 15 Block Storage volumes, for a maximum storage capacity of 10TB each, with no downtime.
Easy setup and migration
Create a Block Storage volume in seconds using our console, CLI, API, or Terraform provider. Easily move your data from one Instance to another by detaching and then reattaching your volumes.

Block Storage use cases
Persistent volumes
Block Storage stores virtual machines' data so they can access it when they restart. Ideal for quickly accessible and easily transferable data and backups. Kubernetes Kapsule automatically uses Block Storage when you create persistent volumes.
High-performance databases
As databases require a lot of IOPS and low latency, Block Storage is perfect for storing them. You can also increase your volumes with no downtime, as your project grows with hot resize to accommodate a frequently fluctuating application workload.
Additional storage for optimized Instances
Expand the storage space up to 10TB on your Instances when you exceed the capacity of your current volume. Each block volume is then accessible as a local drive.
One of the lowest priced SSD storage offers for your Instances
Source
Whereas block storage historically cost $0.10 per GB/month on average (with baseline and burst performance of 3,000 and 16,000 IOPS respectively), Scaleway's Block Storage offers SSD storage capacity for your Instances at just €0.086/month/GB.
Redundant and expandable storage suited to all your workloads
GPU Instances
Accelerate AI and machine learning with the best price/performance ratio GPUs powered by NVIDIA® technologies.
Managed Kubernetes
Deploy, manage and scale containers quicker thanks to transferable data and backups stored in persistent Block Storage volumes.
Managed Database
Your fully managed PostgreSQL and MySQL databases
can scale up to 10TB in seconds with no downtime or interruption and without the need to upgrade the node type, thanks to Block Storage.
Production-Optimized Instances
Reliable, high-performance instances with dedicated vCPU for the most demanding workloads and mission-critical applications.

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 600GB. Block Storage allows you to create bigger volumes that are persistent, meaning that they can live without being attached to an Instance.
For more information, see the comparison table between local storage and Block Storage.
What are the performances expected from a block volume?
Block Storage can reach up to 15,000 input/output operations per second (IOPS) through powerful SSDs.
It depends on the Instance using the Block Storage volume and the block size used.
This guarantees 99.99% availability to all our customers. However, this performance is subject to fluctuation during peak load periods.
How does a block volume behave when an Instance is stopped, deleted or crashes?
A block volume is persistent which means that it can live without being attached to an Instance. Nevertheless, the following can be expected:
- 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;
- When the Instance is deleted via API, all the attached volumes are deleted as well which include the block volumes.
Can I convert my Block Storage volume into a local storage volume?
You can create a snapshot to generate a backup of a specific volume.
Within your Block Storage volume, you can create two different types of snapshot depending on where you want to store it:
- BSSD (Block Storage): This snapshot type can be created from block volumes. BSSD snapshots can be converted to block volumes only.
- Unified: This snapshot type can be created from either local or block volumes. Unified snapshots can be converted into either LSSD or BSSD volumes.
You can also store your snapshot within an Object Storage space for cost optimization!
