Model Number

SD Card

The SD Memory Card measures a mere 24mm by 32mm by 2.1mm.
Its slim, compact design promotes easy handling, an important factor for a "bridge media" which you can move between different appliances.
Using decoder software, an SD Memory Card-compatible device can play music, video clips and more without a drive mechanism like those in CD and DVD players.
This allows the equipment to be more compact and gives product designers new creative freedom. Reliability is also improved through the elimination of skipping on music files.
