Thats a issue with the way RTW handles RAM, its got nothing to do with your hard drive. I seriously doubt you will see any noticable performance increase, your money would be better spent on a better graphics card or more RAM.

Reasonable graphics card, but the processor is Intel Atom 330 (two 1.6Ghz cores). It's not really designed as a gaming machine (though it's markedly better than my previous), so I'm wondering if I'll end up needing a beefier proper desktop when EBII appears. I can't even run EB with all the graphical options maxed out on it.
Your CPU might hold you back a bit, M2TW doesn't support multicores as far as I know, so it will only use one of your cores, giving you in effect a single 1.6Ghz processor.
