How could an SD card such as Sony’s “Premium Sound” Micro SDXC cards improve audio quality?

I saw a 64GB Sony Premium Sound Micro SDXL card listed for the equivalent of $160. It promises higher quality audio from the music files stored on it. Am I missing something? It would seem to me that data is data, and other than the speed of the card, I don’t see how it could improve audio quality.

You can use google translate to read the Japanese Sony page for the Premium Sound cards, if you want to see more: http://www.sony.jp/sd/products/SR-HXA/
It’s snake oil. Very, very expensive snake oil. This isn’t going to make your music sound any better, it’s just going to make your wallet lighter. I’m surprised Sony is hawking this, to tell the truth.
