Error message when trying to enable write caching

[WILLKIRK5]

I am trying to optimize the speed of USB transfer on my HP Spectre X360 15-ap012dx and went into the device manager to change the policies for my USB-C flash drive from quick removal to better performance but when trying to enable write caching on the device it says it is not supported or able to change at this time. 

Does my laptop support write caching?

@WILLKIRK5,

Welcome to the HP Support Community!

I reviewed your post and I understand that you want to know how to enable write caching on the computer.

Don’t worry, I assure you I will try my best to get this sorted.

Write caching is a feature in Windows and it is supported on your computer. You need to make sure that the USB flash drive you are using supports the same.

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.

Removable disks have disk write caching disabled by default for quick removal without having to use Safely Remove Hardware.

Internal disks have disk write caching enabled by default for better performance, but you must use Safely Remove Hardware before disconnecting the disk to prevent data loss.

I hope that answers your question and you have a great day!
