SilverStone TS16 is not the only one that makes problems. There's also - Sabrent NVMe M.2 enclosure (Model EC-SNVE) [1] - UnionSine Dual Protocol M2 NVMe to USB 3.1 [2] > I have got one from Orico and it works ok under both linux and MSWin but= =20 > it can be a bit finicky if it doesn't get enough power, it may for=20 > instance work well with an earlier (slower) type of NVME SSD but not=20 > with a later faster type unless you provide external power to it (usb=20 > hub + power adapter). So, the Orico one has problems as well. Do these problems disappear when, instead of changing the way it's connected to the computer, you add this quirk? > Slowing down all RTL9120 already in the market with this quirk is in my=20 > humble opinion not a realistic solutio. What else do you propose, for those of us who buy this hardware (=E2=82=AC = 50, it wasn't a cheap one), connect it directly to a computer (through the vendor-provided cable, to an USB-C 3.2 Gen.2 connector, as in my case), and then experience 1-2 crashes per day under Linux?
