# Cascading Transfers
By utilizing Cascading, you can offload faster. If one of your destinations is faster than the others, Cascading allows you to copy to your fastest destination and then copy from that destination to other destinations. This lets you free up the source earlier, independent of the verification mode used.
### Requirements
* [OffShoot 25.1](https://docs.hedge.video/offshoot/features/pages/-LSuiRqJ75rjp_khhJjP#id-25.1-cascading-transfers)
### How To Set Up
1. First, set your fastest disk as Destination. This is typically an SSD or RAID. Using a NAS as the primary destination is not recommended, as this will bog down your network bandwidth.
2. Drag the next disk you want as a Destination onto the primary Destination and release when a blue outline appears (Figure 1). Repeat for additional Destinations.
Figure 1 Figure 2
3. A Cascading Group will be created, with an arrow indicating the flow (Figure 2).
4. When you've added a Source and then hit Add Transfers, transfers will be created for each destination. The transfers that cascade from the primary destination will start when the primary transfer has been completed. The Source can be ejected as soon as the cascading transfers start (Figure 3).

Alternatively, you can set up Cascading via the Disk Menu (or right-click a disk); select `Cascade from...` and choose a Destination (Figure 4).

### Advanced Workflows
With an OffShoot Pro license, advanced Cascading workflows are possible.
Copy from your primary destinations to multiple other destinations (Figure 5), or switch to continue to cascade, where each previous destination becomes the source for the next destination (Figure 6).

It's also possible to create multiple Cascading Groups with multiple primary disks acting as sources for secondary disks (see Figure 7).

### Limitations
* To modify your cascading setup, you must drag disks out of Destinations.
* Cascading transfers won't show up in Connect yet.
* Cascading transfers are not [(ASC) MHL aware](/offshoot/features/verification.md#mhl-awareness) yet.
* Cascading from S3 is not supported.
