I'm a bit disappointed. I ran a multiple speed test with 2 different apps on my Samsung Note 9 to find 50-53 write times and 83-87 read times. I know you shouldn't expect the maximum advertised, but I could save money and get the same performance elsewhere. Edit: I sent this back and received a replacement card. The speeds are the same. I decided to call Sandisk and they told me that I need to use a specific card reader and test with a PC to get maximum read and write speeds. sooo Shouldn't I expect more than 60% of the advertised maximum when using the phone the card is intended for? The rep was quick to tell me that the A2 has been optimized for smartphone use when launching apps from the card, which I don't intend to do. I don't see any real advantage in using this card as there are cheaper comparable alternatives.
