hmmm. i think that most maschines have about 128mb of RAM. and the RAM
type most of these "old" machines use is PC100 or PC133 RAM which is quite
cheap. you get an additional 128mb for about 18.- euros. :) not to much
imho.

another thing you have to think about: no HD really likes 24h stress test.
:)
and that.s what you want to do. so better cache in RAM.

and how many seconds "cache" to you need? i think 20s would be enough. and
that is just 10mb. i guess everyone has that amount of spare memory for
a RAM disk. :)
