    With the plastic shroud around the PCB inside, doesn't seem the
    electronics are going to get much cooling. There looks to be an open
    slot on the top of the shell where you use a tang to extend/retract the connector, but is there a slot or holes on the bottom to, at least,
    provide for convection cooling (airflow through the shell)?

    I can't tell if those are holes in the shell opposite the slider side,
    or maybe lenses for LEDs to show through.

    No lights. Holes are for string to secure when carrying like a lanyard?


    Western Digital owns Sandisk. The product page is at:

    https://www.westerndigital.com/products/usb-flash-drives/sandisk-ultra-dual-drive-m30-usb-3-1-type-c?sku=SDDDC2-256G-G46

    The reviews there are less than glowing. Its specs specify:

    Operating temperature range: ???10° ??? 70°C (14° ??? 158°F)

    Well, 158F is going to feel hot on your fingers, but it's not hot to the connector in the computer case. I mentioned the Sandisk forums to see
    what other users of the same product might say about temperature. One I found was:

    https://forums.sandisk.com/t/sandisk-ultra-luxe-256gb-extreme-heat/225662

    "after removing it from my TV after watching a movie" makes it sound
    like the drive was only getting read, not written. Getting really hot
    with only reads seems a defect. Hot on sustained writes would be
    normal.

    Yeah, even idled!



    As the forum thread mentions, if you are worried about the heat damaging
    the USB connector in a laptop, tablet, desktop, or whatever, use a USB
    stub cable to move the USB drive away from the computer case; however,
    you'll probably want to either have the USB drive dangling in mid-air
    from the case USB connector, or lay it on something that can absorb the
    heat, like a ceramic or stone coaster.

    More like burning hot to touch! :(
