[QUOTE="CanadaRAM, post: 331712, member: 15136"] Real RAM responds in nanoseconds (5.4 Gbits per second for intel Mac RAM). Hard drives respond in milliseconds (1 to 1.5 Gbits per second -- but add several milliseconds to locate the starting point of each file). Flash drives respond in tens of milliseconds (.02 to .20 Gbits per second) One problem with flash drives is that they have a finite number of read-write cycles and then they die. Not a problem for cameras storing photos on a daily basis. Big problem for an OS that wants to write and delete files thousands of times per minute. Also with certain types of flash, you can't just rewrite a single data bit - you have to read a whole block, erase the block, and then write the whole block back, with the changed bit you wanted to write in the first place.
