This tutorial will show you how to enable or disable disk write caching for internal storage devices in Windows 10 and Windows 11.

Disk Write Caching for internal storage devices is enabled by default.

Write caching improves system performance by allowing Windows to cache disk write operations in system memory until it is written to the disk. This allows the system and apps to run faster by allowing them to continue without waiting on data write requests to be written to the disk.

However, a power outage or equipment failure might result in data loss or corruption if not written to the disk from the cache yet.

While it's recommended to leave write caching enabled for drives, you can disable write caching for devices if wanted or needed.

For external storage devices, see:

Reference:

You must be signed in as an administrator to enable or disable disk write caching for internal storage devices.

I even disable buffer flushing, unless one has problems with a power, it should not be an issue.

Is it possible to make this a .reg? What if there are two drivers? I have a similar setup to what is in the SS. I have a 1TB and a 4TB that I like to check both boxes on.

Hello, :alien:

Unfortunately not since this is device specific with each their own unique hardware ID.
