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?

Does this mean you are adding 1MByte of fast RAM on an expansion board ?

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 ?
