This tutorial will show you how to enable or disable the ability to create a Dev Drive for all users in Windows 11.

Dev Drive is a new form of storage volume available to improve performance for key developer workloads. Dev Drive is built upon Resilient File System (ReFS) technology and includes file system optimizations and features that provide more control over storage volume settings and security, including trust designation, antivirus configuration, and administrative control over what filters are attached. It has been designed to meet a developer’s needs to host project source code, working folders, and package caches. It is not designed for general consumer workloads such as document libraries, installing packaged applications or non-developer tools.

By default, to give the best possible performance, creating a Dev Drive automatically grants trust in the new volume. A trusted Dev Drive volume causes real-time protection to run in a special asynchronousperformance mode” for that volume. Running performance mode provides a balance between threat protection and performance. The balance is achieved by deferring security scans until after the open file operation has completed, instead of performing the security scan synchronously while the file operation is being processed. This mode of performing security scans inherently provides faster performance, but with less protection. However, enabling performance mode provides significantly better protection than other performance tuning methods such as using folder exclusions, which block security scans altogether.

If you like, you can disable the ability to create a dev drive for all users on the device. This will not affect any current dev drives.

Reference:

You must be signed in as an administrator to enable or disable the ability to create a Dev Drive.
