I formatted it in windows 8 as exfat, tried it again with the SD Tool app and got 22mb/s but when transferring files from PC to the phone it stays between 6 and 7mb/s.
It could be PAC rom messing with USB so I will flash TW 4.3 rom (Goldeneye) to see if it will change something.
It took me 2mins to transfer the 950mb of the rom while in the HTC One days it would have take 20sec...
Report on Echoe rom before flashing the new modem:
Using 400mb test file with H2testw Writing speed: 6.67mb/s and Reading speed : 19mb/s
Weird thing is that it starts first 4 secs with high 22mb/s then drop to 6!!
Dunno if new modem will change something
