An anonymous reader asks: "I've just upgraded the RAM in a bunch of laptops and have several gigs of spare PC2700 memory sitting in a desk drawer. I also have another project which requires a large amount of low latency temporary storage. So, I figured this would be a great place to employ a dedicated hardware ramdisk but I am having a problem finding one that doesn't cost an arm and a leg, or preferably an empty unit that works with my spare memory. I have found many discussion forums which talk about building an IDE ramdisk out of commodity RAM, but have not found anyone that has actually done it. Has anyone on Slashdot found such a holy grail? Is anyone currently working on such a project? Do any of you have the engineering experience and interest to design such a device?" What novel purposes have you done with spare RAM that you haven't had the heart to throw away?"Before you ask, my primary server is maxed out on RAM at 2 gigs, and I am still filling up my 1 gig software ramdisk when I end up with an unusually large data set that needs processing. Yes, I am aware that an IDE device would be limited by the IDE interface for throughput, but I am more concerned with latency then throughput, and IDE is common and simple enough to connect to any of my desktop servers without the need for an add in card."
