There are many such devices like the rocket drive which allow you to use normal SDRAM as a hard drive per say, but they are extremely expensive, and you better make sure as hell your power never fails or else you will loose all the data on the ramdisk device. If you have the money and an ABS though, then by all means go ahead. Don't install the OS or anything else on the ramdisk though, put the page file on the ramdisk. http://www.cenatek.com/product_rocketdrive.cfm ^^^ If you have the money, that is the best ramdisk device that you can buy. You can only have a max of 4GB of space, but thats more then enough for the page file, and possibly a slimmed down version of XP. Although like I said, I would not put the OS or anything else on it because of the data loss issue. Putting the page file on it would be the smartest choice. (and why would'nt you? Having a page file with that kind of access speed would be f***ing kick a**.)
