This document describes the features of Hyperdisk Throughput. Hyperdisk Throughput is best for cost-sensitive and analytics workloads that require up to 2,400 MiB/s of throughput per volume. It's also a good fit for workloads that use sequential I/O and large block sizes.
For more information about Hyperdisk and the other Hyperdisk types, see About Hyperdisk.
You can specify up to 2,400 MiB/s
of throughput for a single Hyperdisk Throughput volume. You can't provision an IOPS
level, but each MiB/s of provisioned throughput comes with 4
IOPS, up to 9,600 IOPS.
Hyperdisk Throughput has a latency profile similar to hard-disk based storage, with average
read latency of 10-30 milliseconds.
To create a new Hyperdisk Throughput volume, see Create a Hyperdisk volume.
Use cases
Hyperdisk Throughput is a good fit for the following use cases:
- Analytic workloads like Kafka and Hadoop
- Cold storage
- Data drives for cost-sensitive workloads
Machine series support
You can use Hyperdisk Throughput with the following machine series. You can't use Hyperdisk Throughput with bare metal instances.
Limitations for attaching Hyperdisk Throughput volumes to 4th-generation instances
If you create a Hyperdisk Throughput volume and attach it to a 4th-generation instance like C4, C4A, or N4, you can only attach that volume to other 4th-generation instances.
If you attach a Hyperdisk Throughput volume to a 1st-, 2nd-, or 3rd-generation instance, you can't attach it to a 4th-generation instance. Conversely, you can't attach Hyperdisk Throughput volumes that were attached to 4th-generation instances to other instance types. In these scenarios, you must create a new Hyperdisk Throughput volume from the existing Hyperdisk Throughput volume, then attach the new volume to the instance.
For example, if you detach a Hyperdisk Throughput volume from a C4 instance, then you can't attach it to a G2 instance. You must create a new Hyperdisk Throughput volume.
To create a new Hyperdisk Throughput volume from an existing volume, follow the steps in Change the type, placement, or location of a disk, or use the gcloud convert command.
About provisioned performance
You don't have to provision performance when you create Hyperdisk volumes. If you don't provision performance, Compute Engine creates the volume with default values that you can modify later. For details about default values, see Default IOPS and throughput values.
If you know your performance needs, you can specify IOPS and throughput limits for a Hyperdisk Throughput volume when you create the volume, and you can change the provisioned values after you create the volume. You can't specify an IOPS or throughput level if you don't specify a size.
Size and performance limits
The following limits apply to the size and throughput values you can specify for a Hyperdisk Throughput volume.
- Size: 2 TiB-32 TiB. The default size is 2 TiB.
- Throughput: 20-2,400 MiB/s,
with the following restrictions:
- Minimum throughput: provisioned throughput must be at least 10 times the volume's size in TiB.
- Maximum throughput: provisioned throughput can be at most 90 times the volume's size in TiB, up to a maximum 2,400 MiB/s. For examples, see Limits for provisioned throughput.
- IOPS: you can't specify an IOPS limit for Hyperdisk Throughput volumes. Instead, the provisioned IOPS depends on the provisioned throughput. Each Hyperdisk Throughput volume is provisioned with 4 IOPS for each MiB/s of throughput, up to a maximum of 9,600 IOPS.
Limits for provisioned throughput
The following table lists the limits for configurable throughput for common volume sizes.
If a size isn't listed, use the following formula to calculate the allowable
values, where x is the volume's size in TiB:
- Minimum configurable throughput:
10x - Maximum configurable throughput:
MIN (90x, 2400)
| Size (TiB) | Minimum throughput (MiB/s) | Maximum throughput (MiB/s) |
|---|---|---|
| 2 | 20 | 180 |
| 5 | 50 | 450 |
| 10 | 100 | 900 |
| 27 | 270 | 2,400 |
| 32 | 320 | 2,400 |
Default size, IOPS, and throughput values
If you don't specify a size or throughput value when you create a Hyperdisk Throughput volume, Compute Engine assigns default values.
The default size for Hyperdisk Throughput volumes is 2 TiB.
The default throughput and IOPS are based on the following formulas,
where x is the volume's size in TiB.
- Default throughput:
MIN (90x, 2400)MiB/s - Default IOPS:
4t, wheretis the default throughput. You can't directly configure the IOPS level.
Change the provisioned performance or size
You can change the provisioned size every 6 hours and its throughput every 4 hours. To learn how to modify size or performance, see Modify a Hyperdisk volume.
Performance limits when attached to an instance
This section lists the performance limits for Hyperdisk Throughput. You can specify up to 2,400 MiB/s of throughput for a single Hyperdisk Throughput volume. You can't provision an IOPS level, but each MiB/s of provisioned throughput comes with 4 IOPS, up to 9,600 IOPS.
This section lists the maximum performance that Hyperdisk Throughput volumes can achieve for each supported instance. A Hyperdisk Throughput volume's performance when it's attached to an instance can't exceed the limits for the instance's machine type. The performance limits are also shared across all Hyperdisk Throughput volumes attached to the same instance, regardless of each volume's provisioned performance.
Achieve higher performance with multiple Hyperdisk Throughput volumes
Certain instances can exceed the maximum performance for a single Hyperdisk Throughput volume—2,400 MiB/s. An instance can achieve these higher limits if you attach multiple Hyperdisk Throughput volumes to the instance.
If an instance's performance limit in the following table exceeds 2,400 MiB/s,
then the instance can achieve that limit only if you attach multiple Hyperdisk Throughput volumes.
For example, the performance limit for a a3-*-8g instance using Hyperdisk Throughput volumes
is 3,000 MiB/s. Therefore, to achieve 3,000 MiB/s of
throughput, you must attach at least two Hyperdisk Throughput volumes to the instance.
The performance limits also apply to custom machine types.
| Instance machine type | Maximum IOPS | Maximum throughput (MiB/s) |
|---|---|---|
| A3 (A3+H100) | ||
a3-*-1g | 4,800 | 1,200 |

Disaster protection for Hyperdisk Throughput volumes
You can back up a Hyperdisk Throughput volume with standard snapshots. Snapshots back up the data on a Hyperdisk Throughput volume at a specific point in time.
Cross-zonal replication
You can't replicate Hyperdisk Throughput volumes to another zone. To replicate data to another zone within the same region, you must use Hyperdisk Balanced High Availability volumes.
Regional availability for Hyperdisk Throughput
Hyperdisk Throughput is available in all zones and regions.
Hyperdisk Throughput Storage Pools
You can use Hyperdisk Throughput Storage Pools to simplify planning, avoid overprovisioning storage, and reduce costs. Hyperdisk Throughput Storage Pools let you to purchase Hyperdisk Throughput storage in bulk. To learn more, see About Hyperdisk Storage Pools.
Pricing
You're billed for the total provisioned size and throughput of your Hyperdisk Throughput volumes until you delete them. You incur charges even if the volume isn't attached to any instances or if the instance is suspended or stopped. For more information, see Disk pricing.
Limitations
- Hyperdisk Throughput volumes are zonal and can only be accessed from the zone where the volume was created.
- You can't create a machine image from a Hyperdisk Throughput volume.
- You can't create an instant snapshot from a Hyperdisk Throughput volume.
- You can't use Hyperdisk Throughput volumes as boot disks.
- You can change a Hyperdisk Throughput volume's size every 6 hours. You can change its throughput every 4 hours.
- To use Hyperdisk Throughput with N4, C4, or C4A instances, see the Limitations for attaching Hyperdisk Throughput volumes to N4, C4, or C4A instances.
