WHen I render to the SSDs it does it a full 5xfaster than rendering to the 7200rpm drive (5 minutes for a 10 minute file compared to almost 25 minutes on the mechanical drive). Not sure why its such a huge difference but it is for sure. Even when I was running vegas from the SSD. This was basic rendering though, not layers upon layers of effects. But for small simple short videos I will render to the SSD and then transfer off later.
