I ordered a samsung microsdhc 32gb class 10 card but I received a samsung plus UHS-I Card. Does anyone use an UltraHighSpeed Card ? I would like to know if this speed class is compatible with our razr i before I open it. Because if not, I will send it back to get the proper one I've ordered.
Thanx.

Yeah I'm not sure on the difference myself but going by the sandisk website they call it a UHS-I card so I'd guess its the same standard

Yeah, looks the same. Thank you. One last thing, when you use it for the first time, did you used the razr I to format it or not ?

I think I did, well I'm pretty sure it does it itself when it mounts the SD card for the first time, but don't quote me on that

Because I was migrating from a class 6 to a UHS-1 I simply dumped the card contents to a folder on PC, and transferred everything - so the formatting was handled by the PC. If you were to let the device handled it.

If you were to let the device format it and used it to copy any existing content over you'd be using horribly slow MTP - much better off with a card reader.

There must be 2 symbols:
- a U with a 1 inside
- a circle indicating the class
it must be at least 10 :)

I confirm that the Samsung microsdhc Plus UHS-1 32gb class 10 works great on the phone. I made a bench yesterday and got 11.9 for R/W
