    What is the best way to have extra memory if you have no SATA port (includes mSATA to M.2)
    This test was done to figure out what port can give you what speed with what medium.

    The Contestans:
    – 1 Sandisk ultra fit 64GB USB3
    – 2 Samsung EVO plus 64GB micro SD (for the 4k Mi Drone, what needs 60 MB write speed)
    – 3 Sandisk ultra XC I 64GB micro SD
    – 4 Sandisk ultra HC I 16GB micro SD

    The Ports:
    – USB 3
    – USB 2
    – micro SD on USB 2
    all on a Jumper 3S Ultrabook

    The Results:
    USB 3      1: 129/30 2: 83/67   3: 44/42   4: 78/9
    USB 2      1:USB3    2: 20/20   3: 20/19   4: 20/8 with USB2 adapter
    USB2       1:38/14    2: 39/37   3: 38/37   4: 38/10 with USB3 adapter
    microSD 1:USB3     2: 24/25   3: 24/25   4: 24/7

    It makes quiet a difference in speed if you put the same fast micro SD card in a micro SD slot or a USB 2 or a USB 3 port.
    Also a USB 3 adapter in a USB 2 port is much faster than a USB 2 adapter in a USB 2 port.
    If you put a fast card with a USB 2 adapter (reader) into a USB 3 port then you are limited to the USB 2 adapter speed what is much slower.

    It is well known that the tiny Sandisk ultra fit gets quiet hot (70 C / 158 F) when moving lots of data, since it has no way of moving the heat out of the USB port confinement.
    The short USB 3 adapter with the 17mm aluminum grip gets also hot to the touch 61 C /142 F).
    While the slow data moving USB 2 adapter even with a fast card and in the USB 3 port stays cool with 34 C / 93 F).

     

    If somebody has a USB 3 to M.2 adapter  and could to a test and post it below, that would be great. Otherwhise we need to wait a few weeks until I get one to test myself.

    I found a test from a Russian with a m.2 256GB Kingspec what is over 500GB read and around 450 write in most cases internal.
    With the USB 3 to M.2 adapter he measures 221/138.

    “tested adapter usb 3.0 immediately ordered which, on aliexpress. The hub connected adapter to usb 3.0. the test results dabbed (ssd connector directly connected to the motherboard, the speed will be higher, features such as but not). seller not consorted. all of good luck!”

    There seems also a difference if you use a fresh formated or a partially used drive to do the test.
    “1st picture new formatted, 2nd picture clean windows installed. It is in beelink s1 4gb, win10 x64. I like it.”

    I finished this test now since I have a m.2 to USB3 adapter.
    I got 430 to 135 via USB
