Review on DMLIANKE M.2 NVME SSD Enclosure Adapter: USB 3.1 Gen 2 Case for PCIE NVME M.2 SSD (Black) by Corey Harris

UPDATE 10/27/19 : The seller sent me a new unit and it works fine. My transfer speed is now 929 MB/s to my SSD. As for the heat issue others have reported, I haven't had a chance to heat it up enough to test it yet. ------ I tried this case with two different NVMe SSD devices and connected it to three different Windows 10 PCs and two Macbook Pros. In all cases it is mounted normally. The problem is SPEED. This case offers a read/write speed of only 40-50MB/s. This is a universal performance barrier, regardless of SSD, host computer or OS. The same SSDs installed in other cases or motherboards show read/write speeds of 1500-2400MB/s. What could be the problem? Maybe I just have a bad body?
