All About Memory Cards For Cameras: Benefits And Advantages

By Rick Newman


Available in various sizes and shapes, memory cards for cameras are compact, efficient and are primarily used to store images. A camera can support a variety of chips depending upon the number of slots or by the variation of the format.

These chips are based on flash memory, a non-volatile form of memory that stores data without the aid of power. They have a large capacity of recording print-quality high resolution images. The card design and the capacities depend largely on the camera being used.

The most controversial factor while selecting memory cards for cameras is the speed of data transfer. Most of the manufacturers specify the speed in MBPS where as it is seen that many use the suffix 'x'. It is known that 1x equals 150kbps. Another criteria used is the card system in the SD card formats.

Standard Digital (SD) is the major type of memory chips. Most of the digital cameras record the images and the movies in one or more varieties of SD memory chips. The size of these chips is similar to the postage stamps and they are available at very cheap rates.

However these chips are largely being substituted by the SDHC format (where HC represents 'high capacity'). The most advantageous factor in these chips is the memory which ranges from 4GB to 32GB. These chips even have much better speed and reliable performance though they are same in size as SD chips. Another type of the chips that have emerged in the market are the SDXC chips. These chips have an inbuilt memory ranging from 32GB to 64GB. These are used in the DSLRs and other high definition cameras.

The professional DSLRs still have the support for the Compact Flash chips even when most of the DSLR cameras have upgraded to the SD formats. These cards are much stronger and larger than SD chips and have an edge over them in adverse conditions.
