Persistent disks

Persistent disks are network storage devices that are durable and have high performance. The disks can be attached to and accessed by the instances. These devices can be used with Google Compute Engine or Google Kubernetes Engine.

Automatic encryption helps us in protecting the disks. We can resize your storage while it is still being used by VMs with no downtime, but you might face some performance issue, though negligible ones.

When to use

We will be using persistent disks when we need reliable and affordable storage with consistent performance characteristics. With standard HDD persistent disks, they are efficient and economical for handling sequential read and write operations. Random IOPS are not optimized on persistent disks.

At the same time, SSDs are used for high rates of random input/output operations per second. These are designed for single-digit millisecond latencies, but often they are not used for archival purposes.

We can use local SSDs that are suitable for temporary...
