While it’s true that write caching improves performance, some precautions need to be taken. Caching these commands allows the computer to temporarily save them until it's written to an external storage device. Write caching is used to improve performance by using the volatile memory (RAM) to collect write commands sent to a storage device. This will allow your system to put more focus on the data transfer which should increase its performance. When doing large data transfers or trying to maximise overall speed of the transfer it is best to ensure that any extra tasks are held to a minimum. NOTE: Enabling write caching will increase the speed of your device regardless of the format you choose.
