Not suitable for the internal memory of the Moto G5 Plus, but can be used as a portable (removable) memory card. I bought two of these to put in Moto G5 Plus smartphones and use them as internal (non-removable) storage. In both cases the G5 complained that the card was too slow and I should use a faster card. I'm not sure why this should be the case. The Motorola doc I have for the G5 talks about using a UHS-1 card and shows the characters that should be on the SD card. This Silicon Power 64GB Elite card has all the right symbols and says it's UHS-1. Both SP cards are properly formatted for internal storage but have a speed warning. I have removed both cards and am looking for faster cards to use at full speed for internal use. Update: I ordered two Samsung 64GB 100MB/s (U3) MicroSDXC EVO Select memory cards (available here at Revain) and tested them in the G5. They have a higher speed rating, are slightly cheaper and there was no "slow speed" warning from the G5.
