Just talking about eMMC and great readers is the problem of accessing eMMC due to the heatsink.
That card is likely never to get used as even the faff of going from SD -> eMMC is preferable to removing a heatsink each time you need access.
I keep looking at that heatsink that I think it is great, but no easy access to the eMMC is not.

Not the greatest of images but you get what I mean or some variation of, even a slotted insert but really its not needed.
Access to the EMMC is though.
