Um. yeah. PURE disk intensive load...and an SSD vs. a slow RAID. Think about that a moment. The SSD is going to win...so big. SOOO big. I don't care what else you got backing it. The CPU won't matter for anything that will drive a SATA SSD, and the memory will barely be noticed for this task. It's all about write performance and seek time, and your SSD wins. A very scrawny laptop with a cheap SSD will run circles around all but the mightiest servers with spinning rust arrays when it comes to disk performance. It's just no contest. Nick.
