This page covers the storage options supported by Cloud SQL, and some key
considerations for selecting the storage option that best fits your instance's
needs.
The storage options available for your Cloud SQL instance depend
on the machine series you
choose. To find which storage option is available for your instance's machine
series, see
Machine series availability.
The solid-state drive (SSD) option is available for Cloud SQL Enterprise edition instances and
Cloud SQL Enterprise Plus edition instances using the
Memory-optimized-N2 machine series only.
The SSD storage option provides an efficient and
cost-effective option for your Cloud SQL Cloud SQL Enterprise edition instances.
When compared to a hard disk drive, SSD is faster and brings more
predictable performance. SSD has high write and read throughput, and maintains
low latency with data access. This makes it a great option to store active
data that requires frequent and low-latency access.
SSD is a Persistent Disk volumes offering that provides durable network storage
devices and is suitable for enterprise applications and high-performance
databases that require lower latency and more IOPS.
For more information, see
About Persistent Disk.
IOPs and throughput for SSD storage type are set based on the machine type
and storage capacity you set. You can't configure the values for IOPS and
throughput.
Cloud SQL Enterprise Plus edition SSD IOPS and throughput limits
The following table shows the maximum values for IOPS and throughput
for the SSD storage option based on the number of vCPUs for
Cloud SQL Enterprise Plus edition instances using the
N2 machine series:
