Yes. U3/ V30 faster cards.
V30 mean 30 MB/s but if you read the specs of memorycards with that brand they will say 130 - 180 MB/s speeds, so the 30 MB/s i think is the rock bottom speed you can expect, of course wit things like this the types and kind of files you move also have a say.
The A rating A1 / A2 is the IOPS the card will handle, so not a absolute necessity to have a A2 card
You can read up on what all these different memory card classes are / mean, many places on the internet.
I have just adopted the first memory card of the new slightly faster kind ( not the very fastest though as they are not supported in dashcams yet, these new ultra fast cards support R/W speeds well over 500 MB/s )
But these new cards have R/W speeds above 150 MB/s or there about.
The first of those i gotten is the Sillicon Power Inspire card ( yellow & black ) R/W = 170 MB/s and 150 MB/s for that one.
Not much luck with previous two SP cards i have, but so far the Inspire have worked in any system i have put it in, so encouraging. ( 70mai A810S and currently in the S1ProMax )

Next card i pick up will probably be the Sandisk Creator. R/W speeds = 190 / 130 MB/s

I might also pick up one of the new GEN 3 Kingston canvas select plus cards, these cheap cards have always been good to me in gen 1 and 2 from years back.
Also looking at Lexar professional sliver plus to add to my test suite.
