Another option is CF cards. IDE <=> CF interfaces are cheap, and the
cards are reasonable. The end result looks like an IDE drive with zero
seek time, BUT it can not be used as a swap drive, or it goes bad pretty
quickly. So MACH or LinuxCNC should work with enough memory. The
problem is that Windows and Linux tend to swap to disk whenever
necessary, and CF cards have limited write counts (10,000 for older tech
was worst case, IIRC.) When a computer gets thrashing at 10 swaps per
second (possible for a fast machine), that is only 1,000 seconds or 1/3
hour.

Of course, a SSD built for swapping of 4 GB would be ideal, fast, low
seek times, etc. Of course, slow memory would be fine and the
controller could be fast (more than 3 Gb/sec.) Sounds like a Gamer product.
