Ak to podporuje microSDHC, tak áno. UHS režim však sotva podporuje. Musíš mať na to čítačku kariet.

Áno ?

UHS Speed Class

The Ultra-High Speed (UHS) designation is available on some SDHC and SDXC cards. The following ultra-high speeds are specified:

UHS-I cards, specified in SD Version 3.01, support a clock frequency of 100 MHz (a quadrupling of the original Default Speed), which in four-bit transfer mode could transfer 50 MB/s. UHS-I cards declared as UHS104 also support a clock frequency of 208 MHz, which could transfer 104 MB/s. UHS-I is the only class for which products are currently available.
Double data rate operation at 50 MHz (DDR50) is also specified in Version 3.01, and is mandatory for microSDHC and microSDXC cards labeled as UHS-I. In this mode, four bits are transferred when the clock signal rises and another four bits when it falls, transferring an entire byte on each full clock cycle.

UHS-II cards, to be defined in Version 4.0, further raise the data transfer rate to a theoretical maximum of 312 MB/s.

UHS memory cards work best with UHS host devices. The combination lets the user record HD resolution videos to tapeless camcorders while performing other functions. It is also suitable for real-time broadcasts and capturing large HD videos.

Cards that comply with UHS show UHS-I or UHS-II on the label, and report this capability to the host device. Use of UHS requires that the host device command the card to drop from 3.3-volt to 1.8-volt operation and select the 4-bit transfer mode.

co viem tak UHS je len oznacenie Ultra High Speed.

Podla infa co som nasiel na nete, pri strceni UHS-I karty do nejakeho zariadenia musi toto zariadenia podporovat SDXC karty, co ten mobil nevie. Ked sa karta UHS-I pouziva v zariadeni ktore nepodporuje UHS-I, tak nefunguje na plny vykon, tudiz je jednoduchsie aj z hladiska kompatibility kupit klasicku microSDHC class 6 a viac. PC citacky pamatovych kariet niesu v tomto problem, ked daco nepodporuje, tak clovek citacku za 5eur vymeni, ale v pripade draheho mobilu nevymenis nic. Navyse sa do toho miesa samotny HW telefonu a jeho OS.

Tak ja viem tak, že proste je to spätne kompatibilné, akurát nepôjde na plný výkon.

v pripade kedy strcis UHS kartu do citacky podporujucej SDXC. Ked strcis UHS kartu do obycajnej SD alebo SDHC citacky tak nemusi ist vobec podla toho co som cital.
