Blue Dragon Posted July 31, 2009 Share Posted July 31, 2009 Hey guys, I've been reading a bit on the interwebs about people who managed to install their OS (WindowsXP) onto a Ram Disk which apparently resulted in a very good performance with fast loading apps ect. I know it's pretty easy to load a live CD of knoppix into RAM before booting and having the same advantages (apps pop up instantly ect.) since there's already a simple menu option when booting the liveCD. Now, I'd like to know if something like this is possible with windows. Nowadays you can easily buy 16GB of RAM for a couple of hundred $$$ which would be far enough to hold your XP or even Windows7. The only problem of course is that all the data is lost when you loose power. Well, not all is lost at once but it gets corrupted over time... What I was thinking about is the following: Install Windows on a normal drive and every time you boot, copy the whole system into RAM before booting it up. That way the booting it self would take a little longer, since copying 5-15GB of stuff from a SATA-connection would take something like 5-10 minutes I guess, but once the system is up, your performance would be awesome, wouldn't it? Later, in order to save your settings, installed programs ect., all you'd have to do is copy the system back onto the HDD before shutting down. Would this be possible? I guess one could use a program like dd that just copies all the bits from one partition or even an image file to the RAM-Disk. What do you think? How would you do this? Would you actually see the difference in speed when using the Ram for your OS as opposed to a normal HDD? Has anyone ever done this in this way? What about actually booting from the RAM-Disk? Does it show up as a normal drive in the BIOS or do you have a special boot loader on an additional drive? Looking forward to your suggestions and answers. EDIT: Just found this: http://www.hyperdrive4.com/index.php Hold max 64GB of DDR2 Ram, but costs 400$ for the case alone, plus whatever 64GB of Ram cost. Not cheap, but 175MB/s read, 145MB/s write sounds pretty decent. Edit2: Oh damn, Sparda just found the same thing. However, as I said it's not cheap. And if I already have tons of RAM in my system, can't I just use that? Quote Link to comment Share on other sites More sharing options...
