[role="_abstract"]
{product-title} supports Hyperdisk Balanced High Availability volumes.

Hyperdisk Balanced High Availability volumes are useful for:

* Protecting your applications from a zonal outage by synchronously replicating data across two zones in the same region

* When you require write access to the same volume in multiple zones

For a single Hyperdisk Balanced High Availability volume, you can specify up to 100,000 IOPS and 1,200 MiB/s of throughput.

To set up Hyperdisk Balanced High Availability disks, see Section _Setting up hyperdisk-balanced disks_.
