#### Region

Use this dropdown menu to select the region that your storage will be deployed into. A region represents a geographic area.

#### Zone

Use this dropdown menu to select the zone to use for your storage. A zone refers to an isolated location inside a region.

We recommend that your storage zone matches the zone of the cluster you’re pairing the storage with.

#### Type

Use this dropdown menu to select the type of EBS storage.

Generally speaking:
- `gp2`, `gp3*`, `io1`, and `io2` are optimized for frequent read/write operations with small input/output size
- `sc1` and `st1` are optimized for large streaming workloads where the dominant performance attribute is throughput
- `standard` is suited for workloads with small datasets where data is accessed infrequently and performance is not of primary importance

*Please note that if you select `gp3`, you'll also need to specify its **Throughput**.

For more details about these types and their use cases, please see [the AWS EBS documentation](https://docs.aws.amazon.com/ebs/latest/userguide/ebs-volume-types.html).

#### Size (GiB)

Use this field to enter the size of your storage. AWS measures disk capacity in both gibibytes (GiB) and tebibytes (TiB). A gibibyte is equivalent to 1,073,741,824 bytes, or 1.1 gigabytes (GB). A tebibyte is equivalent to 1,099,511,627,776 bytes, or 1.1 terabytes (TB).

For specifics on minimums and maximums for each disk type, please see [this AWS page](https://docs.aws.amazon.com/ebs/latest/userguide/ebs-volume-types.html#vol-type-ssd).

#### Restore Snapshot

Toggle this option to **Yes** if you want to restore a previously saved disk snapshot. A new dropdown menu, **Snapshot**, will appear so you can select your snapshot.

For more information about creating snapshots, please see [**Working With Disk Snapshots**](https://parallelworks.com/docs/storage/working-with-disk-snapshots).
