# Volume Limits

Volumes are network-attached block storage. You can use them with Droplets or Kubernetes clusters, move or resize them, and create snapshots at any time.

- You cannot rename volumes. To use a different name, [create a new volume](https://docs.digitalocean.com/products/volumes/how-to/create/index.html.md) instead.
- You can only attach a volume to one Droplet at a time. To use the same data on another Droplet, move the volume to that Droplet using the [move volumes workflow](https://docs.digitalocean.com/products/volumes/how-to/mount-unmount/index.html.md).
- You can attach a maximum of 15 volumes to any one Droplet. If you need to attach more volumes to a Droplet, [contact support](https://cloudsupport.digitalocean.com).
- You can attach a maximum of 15 volumes to any one DOKS node. If your DOKS node needs additional volumes, [contact support](https://cloudsupport.digitalocean.com).
- You can create up to 5000 volumes per account. If your workload requires more volumes, [contact support](https://cloudsupport.digitalocean.com).
- Volumes range from 1 GiB to 16384 GiB (16 TiB) in size.
- One-Click apps do not support automatic formatting and mounting.
- Volumes are not included in Droplet backups. To protect volume data, create [volume snapshots](https://docs.digitalocean.com/products/snapshots/how-to/snapshot-volumes/index.html.md) and create new volumes from those snapshots using the [snapshot restore workflow](https://docs.digitalocean.com/products/snapshots/how-to/create-volumes/index.html.md).
- [Tags](https://docs.digitalocean.com/products/droplets/how-to/tag/index.html.md) for volumes are only supported through the [Block Storage API](https://docs.digitalocean.com/reference/api/reference/block-storage/index.html.md).
- Volume IOPS and throughput depend on the Droplet type the volume is attached to:

  | Type              | IOPS   | Throughput |
  |-------------------|--------|------------|
  | Shared            | 7,500  | 300 MB/s   |
  | Shared (burst)    | 10,000 | 450 MB/s   |
  | Dedicated         | 10,000 | 450 MB/s   |
  | Dedicated (burst) | 15,000 | 525 MB/s   |
  |                   |        |            |
- Some accounts may have limits on volume creation. If you encounter a limit that you are not expecting, [contact support](https://cloudsupport.digitalocean.com).
