I have been trying several different types of SD cards. (I have not tried a 200GB, but that's going to happen soon).
I also have not tried the new Lexar 1800x cards, but based on what's happened with this one, I may not...
I was running into some odd errors lately... like random play just stopping. It goes to the next song, and immediately shows it being fully played on the time bar... then just stops. I resume play, but it does it again after 5 or 6 songs.
So I thought I'd get a really fast card to see if that helped.
This card is amazing in the computers. Writes up to 60MB/s and the Read actually exceeds the 150MB/s claim... to nearly 160 at times (USB3 w/ included Lexar adapter). Used, formatted and used again in the computer with no issues (yes, it gets very hot).
But in the DX-90 it won't scan (crashes) and won't play. Starts a song and then crashes. I'll look in the directory and it will be blank... no songs! I reboot, and the songs are back, but will not play.
I've done a factory reset twice, with and without the card in it... have tried all kinds of things, and no-go. It will not work.
Anyone else have this issue, or have some thoughts about it?
