About Google Cloud Persistent Disk
Reliable, high-performance block storage for virtual machine instances. HDD offers low-cost storage when bulk throughput is of primary importance. SSD offers consistently high performance for both random-access workloads and bulk throughput. Both types can be sized up to 64 TB. With multi-reader mounting, many virtual machines can read data from a single Persistent Disk. Attaching a disk to more virtual machines does not affect aggregate performance or cost. No longer worry about undersizing your block devices. Persistent Disk gives you unlimited flexibility by allowing you to resize your storage while it’s in use by one or more virtual machines with no downtime. For maximum flexibility and minimal effort, snapshots are geo-replicated and available for restore in all regions by default. Snapshots of a block device can take place in minutes rather than hours. Persistent Disks are automatically encrypted to protect your data, in transit or at rest.
