    Flexible drive for USB C and A in one at a great value!

    Flexible drive for USB C and A in one at a great value!
    I realize that products ship with a varying level of quality and that I may have gotten a top-quality drive, but after looking at some of the speed tests people have posted I'm guessing that they ran their tests on a 1st or 2nd gen USB-A port or a USB-3 port on a device or system that cannot take advantage of this drive. The drive is marketed at 400 MB/s and mine landed at 399.79 which is about as close as you can get to that spec without superseding it. I ran this test multiple times on both USB-C and 3.1 gen USB-A ports with nearly identical results. If you're looking for a flexible storage option that can handle both ports and has large storage at a reasonable price this is a great option. I also appreciate that the USB-C female to USB-A male adapter can be used for other cables as well. If you're getting a minuscule fraction of the performance, the chances are that you or your computer are the underlying issues and not Samsung's ability to produce a decent flash drive.
