Hi @liamjames786,

Please contact the WD Technical Support team for the best assistance and troubleshooting:

Another reason why your SSD drive is slow could be that the boot sequence is incorrectly configured. If top priority to boot up is set to hard drive, the fetch and load time for the operating system from an external source will take more time than usual.
