I know this was asked a couple of times already but does RAPID really improve the performance of a system? Is it any better than the native RAM caching of Windows? Is it just like the RAMDisks software available in the market or what? It uses 2GB out of my 8GB available RAM so that's a significant amount. I'm not sure if the software was improved upon over time that someone can consider the performance better nowadays. What do you guys think?
