Understanding BBWC in Windows 10: Benefits and Functionality

Last Updated: Jan 28, 2024 by

Before we dive into the benefits and functionality of BBWC in Windows 10, let’s first understand what it is. BBWC stands for Battery-Backed Write Cache, and it is a feature that allows data to be temporarily stored in a cache before being written to the hard drive. This cache is backed up by a battery, ensuring that the data is not lost in case of a power outage or system failure.

Benefits of BBWC

There are several benefits to using BBWC in Windows 10, including:

Improved Performance

BBWC can significantly improve the performance of your system by allowing data to be written to the cache instead of directly to the hard drive. This reduces the time it takes for data to be written, resulting in faster overall system performance.

Data Protection

As mentioned earlier, BBWC is backed up by a battery, ensuring that data is not lost in case of a power outage or system failure. This provides an extra layer of protection for your data, giving you peace of mind knowing that your important files are safe.

Reduced Wear and Tear on Hard Drives

By reducing the number of writes directly to the hard drive, BBWC can help prolong the lifespan of your hard drive. This is because hard drives have a limited number of write cycles, and using BBWC can help reduce the wear and tear on the drive.

Functionality of BBWC in Windows 10

BBWC is a feature that is available in Windows 10, but it is not enabled by default. To enable BBWC, you will need to have a compatible RAID controller and a battery backup unit. Once these requirements are met, you can enable BBWC by following these steps:

  1. Open the Device Manager by right-clicking on the Start button and selecting “Device Manager.”
  2. Expand the “Storage controllers” category.
  3. Right-click on your RAID controller and select “Properties.”
  4. Go to the “Policies” tab and check the box next to “Enable write caching on the device.”
  5. Click “OK” to save the changes.

It is important to note that enabling BBWC may result in data loss if there is a power outage or system failure. Therefore, it is recommended to have a battery backup unit in place to ensure the safety of your data.


In conclusion, BBWC is a useful feature in Windows 10 that can improve system performance, protect your data, and reduce wear and tear on your hard drive. However, it is important to have a compatible RAID controller and battery backup unit in place before enabling BBWC to avoid any potential data loss. With a better understanding of BBWC and its benefits, you can make an informed decision on whether to enable this feature on your Windows 10 system. Have you used BBWC before?
