There are Flash SSD's and DDR SSD's. I assume you mean DDR SSD's.

You may want to try something like HyperDrive and use Raid to increase the 
size of the volume. See It was reviewed 
at For random access, these 
solid state devices are extremely fast. But sequential access they are 
slightly faster than the fastest hard drive. These devices are also getting 
quite cheap compared to what they cost 5 years ago. I haven't tried it, but 
would love to get my hands on a few of these.
