Learn About The Different Memory Cards

Everyday some new invention occurs in the field of computers. Because of these inventions, there are leaps and bounds of advancement in the computer world. This advancement is based on its advanced technologies and highly featured devices. Computers are aided with different scientific technologies that also enhance its performance.

A memory card is the solid state electronic data storage device in computers. Not only in computers, but it is found in almost all of the electronic computerized devices. These devices are mobile computers, digital cameras, music players, video game consoles and other electronics. Let us continue our discussions on different memory cards and some of the speeds of these cards.

When they are found in some devices they offer power free storage, record ability, and small form factor. The cards that are in solid state use flash memory and those cards that are in the non solid state do not use flash memory. Flash memory cards are replaceable for the hard disks in USB drive and MP3 player etc.

Different cards do different jobs and have different speeds. Some common areas of application are digital cameras, in cell phones and in game consoles. PC cards are a different type. They are the first commercial cards that came out in 1990s. They are used most extensively in the industrial applications. In 1990, more of the cards were invented but with smaller formats than the PC cards. They include smart media, miniature card and compact flash. At the onset of 2000, a number of memory cards were invented. These are Memory stick, SD/MMC and xD picture cards. Since then, the trend seemed to be that the smaller card was preferred over the larger cards.

As a result, compact cards are considered as outdated. PDAs and cell phones are made with ultra small memory cards. It is observed that compact flash and smart media are more successful in digital cameras. Most PCs have a number of built in things like compact flash, memory stick, SD etc. Most of the gadgets that are digital support a number of cards to ensure the compatibility of the gadget.

The speed varies among different memory cards. While buying one for your electronic gadget or buying an electronic device that has them, the speed factor is very essential. The speed actually determines the rate of speed of capturing a picture and the speed of transferring it into the computer. Thus the speed of your device depends on the speed of the cards. The SQ flash memory card is one of the different cards that leave all the others behind in speed. A 1 GB SQ flash card would increase the reading speed to the 24 MB and the writing speed to 12 MB. It shows a wide gulf of difference in the speed of other memory cards.
