What is memory card?

Memory card is an electronic flash memory data storage device used for storing digital information. They are commonly used in portable electronic devices, such as digital cameras, mobile phones, laptop computers, tablets, PDAs, portable media players, video game consoles, synthesizers, electronic keyboards, etc. A memory card is also known as a flash card. And flash memory is nonvolatile, that is the memory card will not lose its data when removed from the device, and the cards can also be erased or reformatted and reused. Erase or reformat memory card will erase all of the data on it, if you want to keep the data, you can backup memory card by memory card backup software in advance. Besides providing non-volatile media storage, a memory card also uses solid state media technology, which lowers the chances of mechanical problems, such as those found in traditional hard drives.

Common types of memory card

There are a handful of different types of memory card on the market, each varying in size, compatibility, and storage capacity. Such as Compact Flash, SD card, Micro SD, MMC, SDHC card, Smart Media card, and so on.Here links to some information on the most commonly used types of memory cards are list below.

CF ( Compact Flash ): A 50-pin connection storage device. Compact Flash is a storage medium which commonly found in PDAs, digital cameras, and other portable devices. And the CF card a very large range of size, in terms of storage capacity, ranging from 2MB to 128GB.

SD card ( Secure Digital Memory card ): A new generation memory device based on semiconductor flash memory, and often used with cell phone. SD card was jointly developed by Panasonic, Toshiba and SanDisk in the United States in August 1999. The size of SD card is just like a stamp, and weighs only 2 grams, but it has high memory capacity, fast data transfer rate, great mobility flexibility, and good security. And it is an integrated solid media and no moving part, so do not worry about mechanical damage.

Micro SD ( Trans Flash ): The smallest removable flash memory cards on the market, range in available sizes of 128 MB to 4 GB, and often used with cell phones and multiple multimedia applications.

MMC ( Multi Media Card ): A multi - function memory card for mobile phones, digital cameras, digital video cameras, MP3 and other digital products.

SDHC card ( Secure Digital High Capacity Card ): An improved version of the standard SD card with a storage capacity up to 32 GB. Because SDHC works differently then a standard SD card, it is not backward compatible with legacy SD devices.

SM card ( Smart Media card ): A type of flash memory card, was also one of the first memory cards to be produced and used in digital cameras and other electronic devices. The SmartMedia card had a smaller capacity, ranging from 2 MB to 128 MB.

Sony Memory Stick: The first mobile storage media developed by Sony Corporation of Japan. It is used in Sony's PSP, PSX series game consoles, digital cameras, digital video cameras, as well as notebooks. It is used to store data, which is equivalent to the computer's hard disk.

xD-Picture Card: A flash memory card, was used in a limited selection of electronic devices, including digital cameras. Olympus and Fujifilm were the two brands of devices to utilize the xD-Picture card.

No matter what type of memory card you use, backup memory card is very important for data security.

Why you need to backup memory card?

Both memory cards and SSDs are stored in flash memory. Although flash memory is non-volatile, it is much harder to recover data than mechanical hard disks if there is data corruption or data loss. So you’d better not use the memory card to save data for a long time. In order to protect the security of data, memory card backup is a good choice.

As the usage time becomes longer, the available space of the memory card may be reduced and the operating speed will become slow. At this time, you may format the memory card to release the capacity of the memory card. If there is a lot of important data on the memory card, you must backup the memory card before formatting.
