Pumeco: a RAMdrive is a portion of physical RAM which acts as a drive, with folders and files, and completely manageable by Explorer as any other drive. One can choose to have a clean one each startup, or to save the contents at shutdown (to a HDD) and get it filled back again at startup. Unfortunately, a RAMdrive cannot survive power-outages and other irregular shutdowns. But it's great for temps and caches, blazing fast.

In my case, the drive is called B:, set to 4Gb max from my 24Gb ram, so I've got 20Gb left for programs etc. When programs need more, the drive can shrink dynamically.

I use the one from QSoft (http://winramtech.hostei.com/RAMDriv/ nowadays) but https://www.raymond.cc/blog/12-ram-disk-software-benchmarked-for-fastest-read-and-write-speed/ presents some comparisons. Take your pick.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
