- What is a memory card?
A memory card is a device offering an easy, fast and reliable way for storing and transferring digital files.
It works like a portable hard disk drive but comes with some superior advantages, since almost every memory card is based on flash memory technology, of having much smaller form factor and being non-volatile and solid state. Making flash memory cards much more durable and reliable than hard disk drives. Memory cards are made by a variety of manufacturers and can be found in different storage capacities and transfer speeds.
- What is the difference between various memory card formats?
There are many different flash memory cards on the market. A few examples of memory cards include; SD cards, miniSD cards, microSD cards, SDHC cards, compact flash cards, memory sticks, Memory stick pro, memory stick pro duo, multimedia cards, smartmedia cards and XD cards. With such a long list of different flash memory card formats to choose from, it may be confusing to find the right memory card.
Before you go out to purchase a memory card, confirm the format(s) supported by your digital devices prior to purchase. An example of your digital camera may only take an XD card (make sure by referring to the manufacturer of the digital device), do not go out and purchase an SD card. The Memory Stick, memory stick pro and memory stick duo are memory cards that work with only a few host devices, primarily with SONY brands.
- How do I use my memory card? What are handling instructions to use the memory card?
It is advised for use of all memory cards to not remove them from devices while data is being processed, in other words; power off the host device prior to removing the memory card. Since flash memory is sensitive to power loss, it is recommended that you remove the memory card in devices that are low on batteries. Data on the memory card cards may be corrupted by sudden power loss. To reduce chances of electrostatic discharge (ESD) avoid touching the metal connectors of memory cards, especially those of the Secure Digital cards, Smart Media cards and XD cards.
