I'm really curious to see the performance of using a SSD just to host the /data folder. Access times (.1-.3ms) destroy Velociraptors (4.0+ms) and read transfer rates are also faster if done 16kb+ at a time. Since you'll only be using the drive for reads, no need to lower lifespan with regard to the read/write limit of MLC SSDs. Is anyone using an SSD for WoW? I may have to try one out sometime soon - prices are getting more reasonable. ~$200 for an OCZ(Samsung) 32GB MLC SSD, or around $450 for a 32GB SLC SSD. They're RAID capable, so if they prove to work significantly better than a raptor, I may have to purchase two and an Areca ARC-1200 RAID controller.
