Probably SanDisk themselves. The Ultra series is a popular purchase because of their price and availability. They are not a good choice because of their high failure rates when used in dash cameras. As well SanDisk will not warranty any cards used in a dash camera unless you use their High Endurance lineup. 13.
So I just bought a Sandisk Extreme 512GB card from the Western Digital website for when I eventually get my Deck, it got here today and I can't help but notice that the font on the card is slightly different than usual, my other sandisk cards seem to use bold text while the lettering on the this one looks thinner. Almost double the price of the EVO Select. The same write speed as everyone else. Both the SanDisk Extreme and EVO Select are very fast microSD cards, but there's a large disparity in the prices . 248 413 338 367 126 354 299 289
