The SanDisk Extreme Pro card is compatible with any microSDHC-slotted device, so you can us it on thousands of microSDHC devices without any issues.  If you use it on older devices you might be speed limited by the host device, but one is usually always limiting the other.

Flipping the SanDisk Extreme Pro micro-SDHC UHS-I card over you can see some of the trace routes on the black PCB and then the eight pins needed for operation. As we already mentioned this is a Ultra-High Speed (USH) memory card. We were told by SanDisk that this UHS-I card UHS-104 interface, which means it supports a clock frequency of 208MHz and should be able to transfer around 104 MB/s!  Down the road we will see UHS-II cards that further raise the data transfer rate to a theoretical maximum of 312MB/s, so don’t think SDHC memory cards are going to be hitting a speed wall any time soon!

We tried the the SanDisk Extreme Pro micro-SDHC UHS-I card in a number of devices and had no issues on any tablet or smartphone. It worked just fine in the Motorola Atrix that came out in February 2011 as well as the  Samsung Galaxy S III that just came out last month.  You can see the Extreme Pro micro-SDHC being inserted into the Samsung Galaxy S III smartphone in the image above.

Installation is a breeze and the Android 4.0 OS detected the card instantly and we instantly had 16GB of extra storage space to do with what we pleased.
