We've heard mentions of AMD's downloadable RAMDisk software which will portion off a part of your system RAM to act as a cache drive to give you all the benefits of an SSD cache drive without the costs.  There are three levels, two free levels which will give you 4GB if you do not have Radeon branded memory and 6GB if you do.  For $18.99 you can get the Xtreme version which will allow you up to 64GB on any type of RAM and will get rid of the upgrade now pop up which you will see on the free versions.  This software should work with any modern CPU from AMD or Intel which is a great move on AMDs part to help make this software popular.  Hardware Canucks checked the boot time with a Super Anti-Spyware scan that is launched during boot which slowed the RAMDisk down a bit however the launch time of CS5 was significantly faster than even an SSD.  Check it out here, or just download it from here.

"With memory prices on the decline and Intel's RST caching offering a great solution for budget conscious buyers, AMD is reviving the idea of memory-based application acceleration. Called Radeon RAMDisk, it promises to reduce load times to mere seconds on even the most basic of systems."
