All About Memory Cards For Cameras: Features

By Rick Newman


The memory cards for cameras come in different sizes and shapes like the other things in the world. The prime function of these cards is to store images. These chips are very small and efficient. There is a variety of chips supported by a common camera. It can be through different slots or by varying a common 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 confusing aspect of the memory chips for cameras is their speed. Some manufacturers quote the rate of speed in MBPS while others just make use of the suffix 'x'. 1x is equivalent to 150kbps. In the SD media formats, card system is used. A class 2 card gives a minimum transfer rate of 2 mega bytes per second, and thus it is an easier method to classify speed.

Standard Digital (SD) is one of the main kinds of memory chips. In one or the other ways most of the cameras use one or more forms of SD memory chips. These cards shape like small postage stamps and are commercially available.

This comparatively latest variant of memory chips has capacities from 4GB to 32GB, alongside a high speed and performance, despite keeping the same older dimensions. Another variety is the SDXC chips. These chips not too common have their capacities from 32GB to 64GB which is set to rise to a whooping 2TB in the coming couple of years. They are demanded in high definition (HD) video capture mainly in the DSLRs and other HD- cameras.

Although many DSLR cameras have adopted the SD formats but the professional DLSRs maintain support for the Compact Flash media cards for cameras. They are larger, stronger than SD chips and more suitable to use in adverse conditions.
