Flash Memory Cards - Sony M2
Sony M2 cards are used mainly in mobile phones, typically Sonys own brand of phone, the Sony Ericsson. These cards are very small at around the size of a mobile phone sim card.
These cards are also able to be placed into a card reader so that any data stored on the card can be transferred to the computer.
While large capacities are available, older devices are unable to support such a large amount of storage so please refer to the user manual for the maximum storage capacity.
