Block Storage

Definition

Block storage presents raw storage volumes to compute instances as if they were physical disks, enabling the OS to format and manage them directly. It offers the lowest latency and highest IOPS of the storage types, making it suitable for databases and transactional workloads.

AWS EBS, Azure Managed Disks, and GCP Persistent Disk are the primary cloud block storage services.
