Got the Jeyi and an SN850X yesterday based on this thread to use with my 2021 MacBook Pro. Trying to determine if I am getting the best possible speed with this combo; test result is attached. Mostly it comports with other reports here but the RND4K result seems significantly lower than what others have. Any ideas? I've tried every version of the firmware on the Jeyi site and got almost identical test results each time.
