this is crazy. i have tried multiple times now, pushing it in fully, changing cables, pushing in fast as u suggested. NO Change. still getting meager 40 MBps.
to test, i bought “Sabrent USB 3.1 Aluminum Enclosure for M.2 NVMe SSD” from amazon and that worked perfectly out of the box without any shenanigans and i got 440 MBps similar to what others were getting.
Also note, that other significant issue is extremely high temperatures. With plugable, it was easily getting to 60-70 Celsius whether on windows or macbook.
With the sabrent one, even after repeated stress tests, it just got warm, but never piping hot like the plugable one.
At this time, i am sure that plugable unit if either faulty or just poorly constructed. i am retuning my purchase to amazon. terribly disappointed with this experience with plugable. u guys seemed to have dropped the ball.
