How to Enable or Disable Disk Write Caching In Windows 10/8/7 [Tutorial]
54How to Enable or Disable Disk Write Caching In Windows 10/8/7 [Tutorial]
Disk Write Caching uses your system memory to cache write commands sent to your storage devices. Write caching allows the program to run faster by not waiting for the slower drive. By default, removable disks have write caching on, and internal disks have write caching disabled.
Disk Write Caching is a feature that improves system performance by enabling write caching on the device. It is a feature, which is available on almost all disk drives these days. The benefit of Disk Write Caching is that it allows applications to run faster by allowing them to proceed without waiting for data write-requests to be written to the disk.
Let’s say you save a file. Now when you save it, Windows makes a note that you want to save the file on your hard drive. This information is saved temporarily in Windows memory, and it will write this file to hard drive later on. After the file is written to the hard drive, the cache will send an acknowledgment to Windows that the file has been written to the hard drive and it can now be safely removed from cache.
Disk Write Caching does not actually write data to the hard disk drive, It occurs after some time, after some time. But in case of a power outage or system failure, the data can get lost or corrupted. So while disk write caching may increase system performance, it can also increase the chances of data loss in case of power or system failures.
If you see the following error messages, you might want to check if disabling Disk Write Caching helps:
Windows Write Delay Failed
Delayed Write Failed.
Disable or Turn off Disk Write Caching
Disk write caching is a feature that improves system performance by using fast volatile memory (RAM) to collect write commands sent to data storage devices and cache them until the slower storage device (ex: hard disk) can be written to later. This allows applications to run faster by allowing them to proceed without waiting for data write-requests to be written to the disk.
While disk write caching may increase system performance, it can also increase the chances of data loss in case of power or system failures before the data from the write-cache buffer is flushed by writing the data to the disk.
Windows defines two main policies, Quick removal and Better performance, that control how the system interacts with external storage devices such as USB thumb drives or Thunderbolt-enabled external drives. Beginning in Windows 10 version 1809, the default policy is Quick removal.
In earlier versions of Windows the default policy was Better performance.
You can change the policy setting for each external device, and the policy that you set remains in effect if you disconnect the device and then connect it again to the same computer port.
You can use the storage device policy setting to change the manner in which Windows manages storage devices to better meet your needs. The policy settings have the following effects:
Quick removal - This policy manages storage operations in a manner that keeps the device ready to remove at any time. You can remove the device without using the Safely Remove Hardware process. However, to do this, Windows cannot cache disk write operations. This may degrade system performance.
Better performance - This policy manages storage operations in a manner that improves system performance. When this policy is in effect, Windows can cache write operations to the external device. However, you must use the Safely Remove Hardware process to remove the external drive. The Safely Remove Hardware process protects the integrity of data on the device by making sure that all cached operations finish.
