Sandisk has designed fingernail-sized, double-capacity mobile memory cards to make storage-intensive features on cellular phones, GPS receivers and still and video cameras more useful and practical. The new microSDHC and Memory Stick Micro (M2) mobile memory cards have 16 gigabytes (GB) of storage capacity, twice as much as has been available.
MicroSD cards, which are designed for older, slot-equipped mobile phones, have a maximum capacity of 2 GB. The higher-capacity microSDHC cards are designed for newer mobile phones, cameras, GPS receivers and other electronic devices. M2 cards are designed for newer-generation Sony Ericsson mobile phones.
