# Persistent disks for sandboxes

Coming soon. Host-local persistent disks are in development and are not available yet.

## Use case: keep development data

A persistent disk will keep a development database or downloaded dependencies separately from a sandbox’s temporary system disk. It will belong to one workspace and one physical host. Only one sandbox will write to it at a time.

## Host-bound storage

The sandbox will have to run on the host holding the disk. If that host is unavailable, the disk will be unavailable. There will be no automatic failover. Today, /workspace files survive a stop and start only until the sandbox expires. That is not a persistent disk.

## Snapshots are not off-host backups

The design takes local snapshots only while the disk is detached. Losing the host’s storage would lose both the disk and its local snapshots. Customer create, attach, restore and delete actions are not yet available.

## Price and status

Persistent disks have no price yet. Check this page for status. We have not set a launch date.
