I had not previously experienced an SSD drive. I do have a RAID velociraptor 10k rpm set up in my PC but that thing also has Intel 965 Extreme 8 core processor. I never did get to appreciate what a fast hard drive does to app launch times until now. I know the RAID raptors are fast but I thought it was the monstrous specs of my pc that made it so. Now that I have this MBA with modest cpu and 2gb ram but with the SSD. I truly can appreciate it. Every application launches so fast. And to think this is with an SSD thats fairly low performing. I have an MBP that I am about to drop a Gskill Falcon 256GB SSD with performance much greater than that of this MBA SSD. I CANT WAIT!
