The price of such safes has really come down. $22 for 128GB was outrageous even in the last year. I verified this with a digital video speed test application (Blackmagic Design Disk SpeedTest) using USB 2.0 on a 2010 Mac Pro running Mojave. The writing speed was 30.9 MB/s and the reading speed was 36.8 MB/s. USB 3.0 on a 2016 MacBook Pro running Mojave was 84 MB/s read and 126 MB/s write. It conforms to the stated specifications. I don't have a compatible tablet or phone to test with. Two minor complaints: (1) It's easy to lose the clear plastic caps that protect the connectors. It would be nice if they were attached by a rope. (2) It's wide enough (19mm) that I can't plug it into a MacBook's Thunderbolt port with the cable plugged into a different port.
