+## Block Cloning Support
+
+Beginning in Windows 11 24H2 & Windows Server 2025, Block cloning is now supported on Dev Drive. Because Dev Drive utilizes the [ReFS](/windows-server/storage/refs/refs-overview) file system format, Block cloning support will mean free performance benefits whenever you copy a file using Dev Drive. Block cloning allows the file system to copy a range of file bytes on behalf of an application as a low-cost metadata operation, rather than performing expensive read and write operations to the underlying physical data. **This results in faster copy completion, less I/O to the underlying storage, and improved storage capacity** by enabling multiple files to share the same logical clusters. Learn more about [Block cloning](/windows-server/storage/refs/block-cloning).

 ## What scenarios are unsupported by Dev Drive? What are the limitations?
 
 There are a few scenarios in which we do not recommend using a Dev Drive. These include:
