UDMA = ULTRA DIRECT MEMORY ACCESS what’s in it for photographers?

UDMA is a protocol developed by Quantum Corporation in conjunction with Intel that supports burst mode data transfer rates. You might be wondering what is a protocol? A protocol is an agreed-upon format for transmitting data between two devices. There are a variety of standard protocols from which programmers can choose. Each protocol has advantages and disadvantages; for example, some are more simple than others, some are more reliable, and some are faster. From a user’s point of view, the only interesting aspect about protocols is that your computer or device must support the right ones if you want to communicate with other computers. The protocol can be implemented either in hardware or in software.
