A compact flash 32 GB is a memory device used to store mass data. It has a flash memory. That is the memory is non-volatile meaning the data is stored even after the power supply to it is removed and the data can be erased using electronic methods and rewritten as per will. A compact flash 32 GB is generally used to store data in electronic devices that are portable or can be connected to a computer. Despite their large dimensions, they are very popular due to their ruggedness and durability. Because of this, they can be used safely in portable devices that may be subjected to shocks and impacts. Also their large size ensures that they have relative mechanical strength and therefore they do not suffer any damages when they are inserted and exerted regularly from the devices.

Compact flash 32 GB cards do not have any cryptographic features like other memory devices and therefore they do not have any license restrictions. Also they are not bound by any standards. Hence they have gained popularity and have widespread usage as they can be made compatible to any device. Another major advantage of these cards is that they can be designed to have much higher memory capacities than their similar flash memory counterparts.

Compact flash 32 GB cards are similar in design to a PC card and can therefore be used as an interface to connect to various peripherals used in a computer such as a magnetic strip reader, bar code reader, GPS systems, blue-tooth devices and even modems. These cards come with a built-in controller. This means that the devices do not need an additional controller to control the card thus reducing costs. Because of their reliability, large capacity and cheap prices, they are extensively used in digital cameras, PDAs, pocket PCs etc.
