Hi the last one i got, I gave the card away to a friend so i didn't try it.

will try the card at the end of the month, the 64GB card recenly had a bid drop in price in hong kong from HKD 1000 to hkd 540 (USD 129 to USD 69.50) will get another soon.

I decided to bet on it, and bought the 64GB microSDXC, class 6, from Sandisk, and I can confirm that it works on the Xperia Ray. I know this is an HTC sub-forum, but since this answers a question I raised here, I thought I might post the answer here as well.

I had to format the sdcard to FAT32 format, I guess Android doesn't read exFat. The formatting had to be done on my computer, I didn't find an option for formatting in Android.
