# Storage

> How your data persists.

## Disk

Fast NVMe storage at `/workspace`. Set the size in `cassian.yaml`:

```yaml theme={null}
disk: 50G
```

Persists across sessions. Follows you if you switch GPU types.

## Cloud storage

Unlimited storage at `/workspace/storage`. Enable with `--cloud-storage` during init, or add to `cassian.yaml`:

```yaml theme={null}
storage: true
```

Good for datasets and model weights. Does not sync locally.

## Exclude

Folders you do not want persisted:

```yaml theme={null}
workspace:
  exclude:
    - "node_modules/"
    - ".venv/"
```
