NitrOS-9 can address a lot more, but it has a fixed amount of system resources and after they are used, any additional RAM is wasted. A RAM drive is a good way to utilize a bunch of additional RAM. Compiling C programs from a RAM drive is definately a lot faster than from a HDD. Which of these three options is better?

If you are going to have an 8MByte RAM disk then you need something to 
load it from quickly such as the SD Card.

Is cache out of the question ?
