Unfortunately, we need to be careful here with our terminology.

SSD used to refer strictly to standard DRAM backed with a battery (and, 
maybe some sort of a fancy enclosure with a hard drive to write all DRAM 
data to after a power outage).  It now encompasses the newer Flash-based 
devices.  My my experience, the two devices have _vastly_ different 
usage and performance profiles.  DRAM-based SSDs have virtually 
unlimited read/write performance (they'll out-perform virtually any 
standard I/O bus, since they're RAM), while flash devices are fast 
read/slower write.

In this case, I think we want the DRAM SSDs.
