Really, it comes down to random-access timing rather than throughput speed; it's the fact that a HDD drive head is having to jump all over the place to load chunks when you've got people all over the map. Even if an SSD isn't as fast throughput-wise as RAM, you eliminate the drive head as a bottleneck. Of course, you'd want to go with a drive/controller combo that can handle lots of IOPS, and that won't experience degrading performance over time (i.e., go with a SandForce drive).
