+1 Even a high-end (ordinary) disk drive can make an appreciable difference. However, by far the most dramatic improvement in long-running GIS processes is made by improving the algorithm. In many, many cases, if your computation is taking noticeably longer than the time required to read all inputs and write all outputs, chances are you are using an inefficient algorithm.

A solid state drive is not made of the same kind of RAM as your computer memory. While much faster than a spinning disk, it is also much slower than the RAM on your motherboard. Of course, you can install an SSD with hundreds of gigabytes of storage ; few motherboards will support that much RAM, even if you could afford it (at least 10X the SSD). Just one more tradeoff point in the space/speed/cost space.
