Quick delivery. Sturdy build quality, and speeds are nice. However, there's some strange behavior under Linux (Debian Buster, KDE): when I was formatting the stick, GUI froze for some minutes, and CPU was at 100% - but in the end it finished the job. Moreover, I got the stick mounted only manually through the terminal. The SATA to USB bridge revealed as JMicron's JMS567, and JMicron is a strong guess for the SSD controller itself, too. Haven't been very happy with JMicron's USB bridges in the past, as many of them died quite fast. Hope is now, this one will last longer ...
