Improve your development tasks with Windows Dev Drive


If you know me, you know that I like to fully optimize my workflow, and a Dev Drive helps to improve it.

A Dev Drive is a virtual drive (using the ReFS technology) that speeds up file-related tasks. This makes it ideal for many daily development related jobs such as building applications, installing packages, running test suites, and so on.

I find that this is the ideal time of the year to make changes before hitting the ground again because you'll benefit from this for the rest of the upcoming year. That's why I recommend you to take a look at a Dev Drive, since it just takes a moment to set up a Dev Drive on Windows.

Here's a comparison after migrating my projects and cache locations (for NuGet and npm) to a Dev Drive. As you can notice, all of the commands that I use frequently have improved by 20% to 25%.

Command Time - NTFS Time - Dev Drive Improvement
dotnet build (cold) 9.362ms 7.195ms 23.1%
dotnet build (hot) 23.11ms 1.856ms 19.7%
ng build 23.803ms 17.648ms 25.9%
npm ci 56.951ms 43.387ms 23.8%

Check it out and see the difference for yourself!


The performance improvements from my experience matches with the numbers that are shared in the Dev Drive: Performance, Security and Control for Developers article.

I also found Maarten Balliauw's blog Test-Driving Windows 11 Dev Drive for .NET helpful and easy to follow, it also contains useful scripts to automate the migration.
