How to On/Off Disk Write Caching in Windows 10/11 – Guide

The disk write cache is a feature which improves system performance by enabling write caching on the device. This is a feature, which is available on almost every disk drive today. The advantage of disk write caching is that it allows applications to run faster, allowing them to proceed without waiting for data write requests to be written to disk. Let’s say you save a file. Now when you save it, Windows notes that you want to save the file to your hard drive. This information is temporarily saved in Windows memory and will write this file to the hard disk later. Once the file is written to the hard drive, the cache will send confirmation to Windows 10/8/7 that the file has been written to the hard drive and can now be safely removed from the cache. Disk write cache does not write data to hard disk drive, it happens sometime, some time later. But in case of power failure or system crash, data can be lost or corrupted. So while disk write caching can increase system performance, it can also increase the potential for data loss in the event of a power or system failure.
