Many devices these days are capable of storing data. Previously, the personal computer was the go to device for storing all kinds of documents, audio files, video files, images, and other file types. Now certain file types may be transferred to laptops, digital cameras, mobile phones, portable media devices, and even peripherals. Early devices had their own internal memories and data transferring was made possible by data cables. Modern devices expand on these options allowing data to be transferred using wireless technologies like Bluetooth or stored in digital memory cards that can be taken out and placed in other systems.

Memory cards come in different sizes and shapes so it is important to know the common types of memory cards because not all devices support all types.

SD (Secure Digital) Cards

SD cards are the most popular types digital memory cards as of July 2010 because they can be inserted into various types of devices. You can often find the slots where you place SD cards in digital cameras. The standard SD card is around the same size of a postage stamp and can store a large amount of memory compared to the small variations. Capacities can go up to 64 GB although there are 128 GB models in the making. Mini and micro SD cards use the same storage technology, but are smaller to fit in mobile phones and other portable devices. Ordinary models have impressive transfer speeds equivalent to about six times the speed of an optical disc. Later models are even faster. If you want some added protection, you can get the SD card that has a write protection switch making it impossible for viruses to spread to these memory cards.

MMC (MultiMediaCard)

MultiMediaCards have a similar appearance to the SD cards with a noticeable cut on one of the corners indicating the front of the card. However, these digital memory cards are slightly thinner a bit smaller. However, some memory card readers can read both MMC and SD formats. In this case, it is better to buy the SD card because MultiMediaCards have a slower transfer rate than the SD.
