SD Card
Compact and Powerful, Ideal for Small Products
The SD memory card measures a mere 24mm x 32mm x 2.1mm approximately the size of a typical postage stamp. The slim, compact design promotes easy handling, an important factor for a "bridge media" that can be moved between different products. Using decoder software, an SD 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 and video files.

miniSD Card
Smaller Size Offering the Same Power, Reliability and Speed as the SD Card
The miniSD card standard was developed to meet continuing industry demands for smaller mobile phones. The miniSD is just 37 percent of the SD card's size, and it packs all of the storage power, speed and other benefits into a small card - including copyright protection. By inserting the miniSD card into a miniSD adapter, you can share a variety of digital data among full-size SD card-enabled products.

microSD Card
Smallest Size Card Featuring the Power, Reliability and Speed of the SD Card
Like the miniSD card, the microSD card standard was specifically designed for the ever-changing and fast- growing mobile market. Approximately the size of a fingernail, it is even smaller than the miniSD card and about one-fourth the size of a full-size SD card.

Wide Market Adoption
The microSD and microSDHC are the leading memory card standards adopted by mobile handset vendors because of their ultra-compact size and widely supported standard SD interface.
Although primarily used with mobile phones, the microSD standard also is supported natively in a variety of hand-held GPS devices, portable audio players, video game consoles, expandable USB flash memory drives and computer tablets.
Compatibility and Interoperability
All microSD memory cards are backward compatible with SD standards-enabled electronic devices. By using an appropriate adapter, the microSD memory card can easily and quickly be inserted into any device that supports a full-size SD or miniSD memory card.
