FLASH STORAGE DEVICES
DOC
vs. DOM:
DOC is a proprietary design by M-Systems.
The motherboard or SBC needs to have a special circuit
(connector) designed to support DOC. Because of the proprietary
design, DOC is expensive versus other storage media.
DOM uses the IDE interface and it can be used by all
motherboards and SBCs with an IDE interface. DOM is getting popular
since it can be procured from a variety of suppliers and therefore
less expensive than DOC.
CFC/PCMCIA
Flash Card:
A motherboard or
SBC needs to have a Compact Flash Socket or PCMCIA Socket to support
CFC or PCMCIA Flash Card. Using
these media allows one to swap from one machine to another. Also allows portability, able to move card from one machine
to another, making upgrades much quicker and easier.
CFC is an alternative to DOC and DOM.
