Very nice for maps, OSes, injector cartography and telemetry data for track day... Too bad that we never get some essential spec as TBW as you stated... Nice review.

I see someone didn't do their homework. V30 is a part of the SD standard for Video Speed Class, where it indicates that it can sustain 30Mb/s write speed for video applications that need it. It is not the model name of the microsd card as implied by your review. More info is available on the SD association website. I suggest you give it a read and fix your article accordingly. https://www.sdcard.org/developers/sd-standard-overview/speed-class/
