Block storage volumes are virtual block storage devices, similar to a USB hard drive for a physical machine, that securely store data in the form of fixed-sized blocks. These SSD-based volumes are managed independently and can be attached or detached from a compute instance on-demand to expand its storage at any time. know more about IDrive Compute Volumes.

Volumes cost $0.10 GiB per month and volume size can vary from 1 GB to 1 TB.

Note:

• Charges accrue hourly for as long as the volume exists
• You are charged for volumes whether or not they are attached to an instance.
