Google Cloud Persistent Disk and Hyperdisk

Google Cloud block storage pricing

Persistent Disk, Hyperdisk and disk snapshots, priced in 48 regions. Regional and high availability disks use Google's own rates, not the zonal rate doubled. Looking at AWS instead? See EBS pricing.

Hyperdisk

Capacity plus the IOPS or throughput you provision, with a free baseline on Balanced.

Snapshots

Incremental backups billed on the compressed data stored.
