From the looks of it, only the 'V90' logo, which means it can sustain a 90MByte/s write speed. I suspect the non-V90 is from an older batch before it went through the certification process to get the logo added.

Yeah that's what I though also, but any idea what speed the non V90 can sustain?? Wondering if there is actually any difference...

I haven't noticed any difference in the when reading and writing it in my card reader with different generation "300MB/s" cards, but all my cameras are a lot slower than the card reader. So I'm hesitant to say there will be no difference in the camera when the card reader shows identical results.
