This Sandisk Extreme Pro is performing at 45MB/s for both read and write speeds, which is lower than Kingston UltimateXX. However, it has been quite a speedy memory card that is better than Class-10 SDHC card.
This new Sandisk Extreme Pro SDHC UHS-I card is using UHS technology (Ultra High Speed) from the SD 3.0 specification, and the card is available in the range of 8GB to 32GB for the price range between $109.99 and $349.99.
