sandisk mobile ultra (red and grey version)

im thinking of getting sandisk mobile ultra for my xperia neo V. but will my phone be able to get the 30mb speed? because my phonw is not high end? so is it worth investing?

it will most likely not utilize the full speed. that said you will probably see faster load times for application stored on the card compaired to slower cards. other than that you would only see the speed when using the card to transfer files from a computer.
