CS6 and Scratch Disk Performance

Background to this - I am running my computer with 20GB of RAM running at 2133MHz, have a RAM disk utility software that can partition my RAM to run full time as what the computer thinks is another local disk (super handy for transferring files stupidly fast by the way).

So I'm wondering is if anyone on here has done this, or used anything else on PS (Premiere has RAM allocation but no scratch disks), to where you use one or more scratch disks other than your C:/ drive to make PS run faster. It's kind of an odd thing to try so if no one has, then oh well. But so far it seems to run most operations faster than just allowing it as much RAM as possible.

Also wondering because if anyone has tried this I'm curious to see if it would be more advantageous to use two smaller scratch disks on RAM (say 2x4GB ones) versus one larger disk (1x8GB). But that ultimately comes down to the architecture of PS coding, as it might be coded to try to only use two when absolutely necessary.

But if no one has done this, RAM disks are still legit for photography and just transferring media off of cards or holding it there and dumping to other external HDD's in a hurry. (I know you can only transfer files as fast as your slowest drive/cable, but it is often much faster for some reason actually)

I guess I probably just don't understand what you're talking about, but I feel like what you're trying to do won't change anything? I always run my scratch discs on my external because you rack up a few gigs every project. Not sure if RAM allocation is gonna do much for you, only options I've ever seen for RAM is how much RAM adobe can use. I run 16gb and apparently adobe can only use 13 or something but I definitely use all of my RAM exporting.

Sorry maybe I didn't explain it well, if you download some software, it will partition whatever size RAM disk you want, so what happens is your computer thinks you just installed another drive in your computer, and you can format it to whatever. Right now I have a 10GB drive (labeled K:/ for me) right next to my C:/ drive, but the difference being that instead of it even being an HDD or SSD even, it's as fast as RAM, because the image is on my RAM. So I use it for whatever, and as the primary scratch disk for PS. But yeah I still have 13GB allocated on PS as normal

Oh ok I get it now. Still, that doesn't seem like it would change anything though? Like I said I and everyone else in the world runs their scratch on an external. I think what would be faster if anything would be installing the program files on said partition of RAM. I run my program files on SSD and its pretty damn fast when it boots up but otherwise its the same speed as if it were on a HDD.

Yeah I need to get an SSD like pronto, but I've also done that - installing my programs on RAM, pretty fun actually haha
