Hi guys,

I have bought a this case and this ssd disk from Amazon.

I have assemble everything, format as APFS (Mac user) and just do speed test, and the results are worst then a mechanical disk.

The case are directly connect to a USB C port with a cable length of 20 cm, that came with the case.

% dd if=/dev/zero of=test1Gb.bin bs=1G count=1

I see on my PC the interface of USB C is a JMicron, its possible be a bad case?

Thanks you.
