Until the day when all devices have ultra-fast broadband wireless internet access as well as sync'n'store features with cloud computing services, memory cards will remain the most convenient, pocketable storage medium.

Today we will benchmark Kingston 's UltimateX 100X 32GB SDHC. As its name denotes, the card is in the Class 10 100x range aimed at the enthusiast. It comes in capacities of 8GB, 16GB and 32GB and we will test the 32 GB version. Kingston quotes speeds of up to 15MB/s write and 20MB/s read, meaning that the SD card should be fast enough for storing HD video.
