The Uses for Standard CF Cards VS Ultra Compact Flash Cards
The CompactFlash otherwise known as a CF card is a popular memory card developed by SanDisk in 1994 which uses a flash memory to store data on a very small card.
The CompactFlash card makes adding data very easy to a wide variety of computing devices which includes digital cameras and music players, desktop computers and personal digital assistants, digital audio recorders, and photo printers.
The CompactFlash measures 43 X 36 mm (which is about the size of a matchbook) based on the Personal Computer Memory Card International Association specifications.
It is also available with storage capacities ranging up to 1 gigabyte with higher capacities corresponding to higher prices.
The CF Card is similar in size to the SmartMedia card, but larger than the newer, postage stamp-sized alternatives, MultiMediaCard and Secure Digital (SD) card.
Since flash is nonvolatile memory, stored data is retained even when a device's power source is turned off or lost completely.
An Ultra CompactFlash provides a transfer rate which is twice that of SanDisk's standard memory cards, this makes them incompatible with the following devices BR-864, BR-600, BR-900CD, and the BR-900 as they tend to work better with a slow speed compact flash making the SanDisk 1 gigabyte Compact Flash Card ideal for use with these types of devices.
There are some adapters available for use with the CompactFlash in order to enable access through a standard diskette drive, USB (Universal Serial Bus) port or PC card slot.
Most platforms and systems that support the PCMCIA ATA (Advanced Technology Attachment) standard also support the use of a CompactFlash.
CF cards feature a solid-state construction making them a lot more rugged than most traditional storage devices.
The operating shock rating (basically, what height can you drop them from and have them still work) for CF cards is 2,000 Gs compared to a 100-200 G rating for the mechanical drive of the typical portable computing device.
This translates to a drop to the floor from 10 feet, as compared to a single foot for the mechanical disk drive.
Some high-end version, Ultra CompactFlash card are optimized for more demanding photography, such as a quickly shot succession of high-resolution pictures, or pictures of a moving subject, such as a bicycle race enabling the camera to save pictures quickly and get the camera ready to capture another image.
