Persistent storage consists of persistent disks that are durable network storage devices that are mapped to your instance. This logo represents persistent storage:
These disks can be used as regular storage disks and the data stored on them remains on the disk until it is deleted. The data on a persistent disk is redundant and also optimized for performance. Persistent disks are independent of any compute instances (virtual machines), so you can detach and re-attach a persistent disk to another compute instance. If your instance is deleted, your persistent disk data remains if you choose not to delete it. Persistent disks are offered in standard hard disk drives or solid state drives and can be resized at any time. Here is an example of a boot persistent disk for a Debian VM:
A compute engine, by default, gets deployed with one root persistent disk that...
