I remember a company in Australia called Platypus Technology (http://en.wikipedia.org/wiki/Platypus_Technology http://en.wikipedia.org/wiki/Platypus_Technology) came up with something similar whereby they loaded up a full-size PCI card with 4-8Gb of RAM and then this would appear as a 4Gb hard-drive to the OS. Then you just place the DB files or swap files onto this drive and Boom! instant speed upgrade for DB or OS doing disk-work... Apparently they are no longer around.
