Well your microsd is uhs-i because prior to uhs, microsd maximum speed is 25MBps.
Your read speed is physically impossible without uhs bus speeds.

Uhs-i has a 50MBps and 104MBps version. Looks like our phone is topping out at 50 which means it only supports sdr50 or ddr50.

It means 25MBps in read or write?

EDIT: It means 25MB/s transfer, no matter read or write. With Toshiba Exceria 16G I have 38,8 MB/s read and 22,5 MB/s write.

But mine just says class 10 on the card.

Unlike the Note 3, which has USB 3.0, the Z2 only has a USB 2.0 connector, so you're going to be capped transfer speed-wise.

Hey guys! Here is my test of Z2 with SanDisk Extreme PLUS UHS-I 64Gb
Honestly, I've expected faster Reading.

That's 34.8 for read and 14.4 for write (Internal SD Card). Sometimes this benchmark shows incorrect names/sections. But you won't be fooled if you'll check the size of memory in the description.
