Cache

I'm wondering if something like this exists.

Basically a program that'll load a "directory" into memory (RAM) and you can access that chunk of ram like a normal hard drive and the background program would monitor any changes to the "virtual" disk [in ram] and flush it out to real disk {in the background} ever so often.

So you would just hit the ram like a normal disk and get super speed when accessing files. The downside would be losing data during a power outage before it had a chance to flush to disk.

I don't want none of those solid state drives. I'm talking about using the memory already in the computer. Does something like that exist?

probably looking for somthing like RAMdisk, but think you'd have to save its state to the disk manually when needed, maybe make a scheduled backup of the disk through task manager.

RAMDisk - there's a blast from the past. I thought everyone gave up on that stuff 15 years ago

The only significance thing to consider is how much RAM are you going to use? If the file(s) are too big and you commit too much RAM to RAMDisk, you then risk having the OS constantly swapping memory to page files and that slows you down.

It's no blast from the past. Linux has had this for a long time. It's called tmpfs, a filesystem that exists in RAM and can be swapped out when necessary. Those Linux LiveCDs use it to avoid having to write out to a physical hard drive. It's useful for lots of other things, too, because it is very fast and not permanent.

I used RamDiskXP to create a 6gig ramdisk. Pretty efficient program, can't remember if it's free or not, been ages since I used it. Gives insane results in benches
