title: "Volumes"
description: "Volumes: disks of a project's that outlive the sandboxes that have them, each a block device with its own ext4, kept whole in the object store and on its node's NVMe as far as its cache goes (`cache_bytes`), and mounted read-write by one sandbox at a time, on any node of its region. A snapshot of a volume is a version of it in the object store, nothing copied: taken (`POST /v1/volumes/{id}/snapshots`), forked into a new volume, restored to, and mounted read-only by any number of sandboxes at once (`mode` `snapshot`); it outlives its volume, and is billed for what it keeps alone. A volume was called a Drive until 2026-10-28: `/v1/drives` (and `/v1/sandboxes/{id}/drives`, `/v1/drive-snapshots`) answer the same calls as they did, for the clients from before."

Volumes: disks of a project's that outlive the sandboxes that have them, each a block device with its own ext4, kept whole in the object store and on its node's NVMe as far as its cache goes (`cache_bytes`), and mounted read-write by one sandbox at a time, on any node of its region. A snapshot of a volume is a version of it in the object store, nothing copied: taken (`POST /v1/volumes/{id}/snapshots`), forked into a new volume, restored to, and mounted read-only by any number of sandboxes at once (`mode` `snapshot`); it outlives its volume, and is billed for what it keeps alone. A volume was called a Drive until 2026-10-28: `/v1/drives` (and `/v1/sandboxes/{id}/drives`, `/v1/drive-snapshots`) answer the same calls as they did, for the clients from before.
