Hundreds of manufacturers market thousands of memory cards and devices built to SD standards in a variety of storage capacities, speed classes and three different physical sizes: SD, miniSD, and microSD. SD memory cards are typically used in personal computers, video cameras, digital cameras and other large consumer electronics devices. The microSD and miniSD cards are commonly used in smaller electronic devices like mobile phones and tablet computers. Some memory card manufacturers offer adapters allowing microSD cards to fit a traditional SD card slot. This gives you even greater versatility and flexibility to use the card in a mobile phone as well as a computer or video camera.

To determine the right card to match your device, always consult the device's user manual or contact the manufacturer. All memory card options are readily available in the marketplace, produced and distributed by a wide range of manufacturers, in retail outlets around the world including drug stores, electronics and computer shops and Internet sites.

Note: SD memory card and SD host device are the generic terms for any memory card or device built to SD standards. SD Association does not produce, market or sell any product; it creates standards and then promotes the adoption, advancement and use of SD standards used by competing product manufacturers that make interoperable memory cards and devices. For questions related to products, please contact the product manufacturer. 

Choosing the Best Card - What Memory Capacity Do I Need?

Manufacturers produce SD memory cards in a range of memory capacities designed to fit your needs and budget. Today, products using the SDXC standard will have the greatest memory capacity and fastest performance when using Ultra High Speed (UHS) standards. Products using the SDHC and UHS standards will also enjoy the fastest performance. Your device's users manual should help you select the memory card standards that are right for your device.

You should consider how you will use a memory card to determine the right memory capacity and speed choice. For cameras, consider the quality of the picture resolution of every photo, and for your MP3 player, the bit-rate required for smooth playback. Take a look at our reference chart that illustrates the various storage capacities provided by our standards.
