In numerous consumer electronics devices that are used today, memory cards are a popular medium of storing data. Some of the devices in which these cards are used include cellphones, digital cameras, laptops and even handheld devices. This type of memory is non-volatile and they retain their data even when they are removed from the device. Moreover, it is also possible to erase the data from memory cards, format it and then reuse it again for storing something else. Compatibility, capacity and price are the three factors that most people consider when purchasing memory cards. Nowadays, wholesale memory cards are available so price isn’t an issue anymore.
Today, these memory cards have become an extremely convenient and reliable tool because they enable users to store data rapidly for using or transferring it. The memory cards are extremely small; almost the same size of a postage stamp. This makes them quite portable. Apart from that, memory cards are able to stand rugged environmental conditions, such as shock, vibration, a fall and even high and low temperatures. They also boast flash memory capabilities and are therefore extremely similar to USB flash drives.
A quick survey of the market will show that different memory cards can be found. Some of the popular ones are:
SD Cards: These are perhaps the most popular digital memory cards, which are used in cameras and mobile phones. They are quite small and will work well with all devices that have SD written on them. Different capacities can be found in these cards and people can select them according to the purpose for which the card is to be used. They also have a write protect switch.
Multimedia Cards: The size of SD cards and these MMC cards is the same. However, the capacities of MMC cards vary. A device that is compatible with an SD card will also accept MMC cards. But, a device that accepts MMC cards will not be compatible with SD memory cards.
Compact Flash Cards: These are another type of wholesale memory cards and are extremely common. Mostly used in cameras, they are a bit larger than the SD cards. Nevertheless, these cards are highly reliable and are even cheaper than any other type of card. A write protect switch is not included with these cards, but the content can still remain protected.
Mini/Micro SD Cards: As the name indicates, the same technology is used in these cards as the SD ones. However, they are a bit smaller in size. In order to make them compatible with SD card readers, they are usually available with adapters. Furthermore, they are especially designed for portable devices such as an MP3 Player or mobile phones.
Memory Stick: Majority digital cameras and handheld devices utilize this memory stick. They are basically a smaller version of an SD card, although previously their size was larger. They are typically used in products of Sony, the Japanese company and are a bit expensive.
These wholesale memory cards can be used by people for their own purpose.
