SanDisk today introduced a new line of Mobile Premier memory cards, performance-oriented microSD cards that allow consumers to quickly transfer content to and from their mobile phones as well as increase storage for videos, music, ring tones, digital images and other files.

SanDisk Mobile Premier cards also feature SanDisk's TrustedFlash technology, which allows network operators to sell premium content that can be downloaded directly to mobile phones, stored on the cards and played on other TrustedFlash-enabled devices authorized by the network provider.

The fingernail-size cards come with an adapter to fit standard SD card slots. Key advantages of SanDisk Mobile Premier cards include:

- Using a card reader or cable attached to a PC, consumers can side-load music tracks, images and videos to / from a SanDisk Mobile Premier card more rapidly than with a standard card. Read / write speeds are 10 and 9 megabytes (MB) per second, respectively.

- Since most mobile phones have limited on-board memory, the SanDisk Mobile Premier card will allow users to store more songs, still images, videos and other content on their handsets. For example, a 2 GB Mobile Premier card can store 500 MP3 songs for about 32 hours of playback time.

All SanDisk Mobile Premier cards are based on the TrustedFlash platform, which can allow users to play back premium content on any TrustedFlash enabled device within the network. Mobile network operators and other content providers can use TrustedFlash technology to produce preloaded memory cards as well as store content, such as music and ringtones, that is purchased online.

SanDisk Mobile Premier microSD cards will be offered in 1 and 2 GB capacities this spring, with suggested retail prices of $44.99 and $69.99, respectively.
