Anyone know what speed Thinkware micro 128 cards are? A1/A2/A3?
Thanks

In my experience, it's not the headline speed of the card that matters; it's the ability of the badly fragmented card to maintain a reasonable, uninterrupted write speed while also deleting older files at the same time.
It's a whole different world to the published speed tests.
Some surprisingly 'on paper' low spec cards cope well while some surprisingly 'on paper' fast cards - usually mid-priced cards claiming to offer top-end speeds - end up stumbling, momentarily interrupting the ability of the cam to write in-progress recordings to the card, and causing cams to shut down intermittently.
