Micro SD card: Maximum Supported Read/Write Speed Rating?

[kasperski97]

I want to purchase a 64GB Micro SDXC card for my Sony Xperia SP and would like to get the fastest card (read/write speed) compatible with (i.e. useable by) the phone, but I do not want to waste money buying a card that has a faster read/write speed than the maximum speeds supported by the phone. What is the maximum read/write speed of the Xperia SP for micro SDXC cards and what would you recommend?

Indeed,it does support it but officially it is not recommended.

I decided to purchase this card: http://www.amazon.com/Kingston-Digital-64GB-MicroSDXC-SDCA10/dp/B00L2CAJA6

In A1 SD Bench have these results:
Read: 32.37MB / s; Write: 32.52MB / s
