Although it cost far too much, and is horribly small, I do <3 my SSD, everything loads noticeably faster and there's the added bonus of it being extremely hard to damage compared to a HD.
Just noticed Gombur's link and saw it has Total Annihilation Commander Pack on it. By far the best RTS game I've ever played, and even if the graphics are somewhat outdated now the game play remains as good as ever.
Not sure it does tbh, and the lower level battle take a lot less time, with no possibility of losing so it'd probs work out better to fight them either way.
