Why ReFS Is Not Commonly Used on Windows 10?

This guide provides a practical overview of ReFS Is Not Commonly Used on Windows 10, including its main features, benefits, limitations, and important considerations.

1. Unable to install the Supported operating systems on the ReFS partition

The first drawback of ReFS is that it does not support the installation of any Supported operating systems, even Windows Server editions. ReFS currently serves data storage purposes only. Windows or Linux cannot determine if a ReFS drive is bootable.

2. Limited compression and encryption support

In the current version, ReFS does not support file-level encryption and compression and it does not support Windows Bitlocker very well, as opposed to NTFS which is fully compatible.

For a person with a large amount of data, compression is an important feature. Similarly, encryption is also important in protecting sensitive data.

3. Performance limitations

Unlike NTFS, ReFS consumes more system resources and has more impact on the drive's IOP. In a server environment, this is not a problem, but on a normal PC this may affect usage.

The larger the ReFS drive's array, the more RAM it will use, the processor cycle and the IOP drive to check the integrity of the file.

4. Can not install the application

Like the Supported operating systems in the first reason, ReFS drives do not support the installation of any applications or programs. The reason behind this is the lack of hard link support in ReFS.

Very few programs are allowed to be installed on a ReFS drive, and even programs that can be installed have trouble running.

5. Profit

The last reason is not related to technology but mainly to business strategy. Like Windows 10 S that only comes pre-installed on Surface laptops, Microsoft wants to force users to upgrade from Pro to Pro Workstation with this tactic to increase sales.

Although optimizing the Supported operating systems for server hardware is a big and expensive task, disabling the features available in a version is certainly not very user friendly.

What to do if there is a ReFS drive?

If you already have a drive or VHD in ReFS format, your data won't go anywhere. Microsoft only disabled the ability to create new ReFS drives and you can still access ReFS drives. Also, this restriction will only take effect with the Fall Creator Update, so you can still create ReFS partitions.
