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 (beta) 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.

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! Discover the steps to create your snapshot here.

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.

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.
