# Adding Storage
When providing storage on Sia, you must allocate a location on your disk that `hostd` will store any uploaded data from renters. This is referred to as **volume**.
**Volume** can be located anywhere on the local or external drives, and you can create multiple volumes to combine storage from multiple drives.
## Creating volume
Go to `hostd`. If you're asked to unlock the UI, use your custom password if you've set one. If you haven't got a wallet set up in `hostd`, visit our [Setting up `hostd`](https://docs.sia.tech/provide-storage/setting-up-hostd) guide; otherwise, choose from the sidebar **Volume**.
Click on the **Create Volume** button in the top right-hand corner.
1. Enter a name for the volume. We recommend something simple, like *hostdata1.dat* or *data1.dat.*
2. Now select a folder to store the volume file.
3. Lastly, enter a maximum size for the volume. This is the maximum amount of data stored in the volume.

4. Click **Create** to add the volume to `hostd`.
### Checking the status
After clicking **Create**, the volume will be displayed in the volumes list. Depending on the size of the volume and the filesystem, it may take a while to provision the new volume fully. The progress will be displayed in the UI.
