Good RAM Disk software?

None of them come close to Primo Ramdisk in pure terms of performance. But OSFMount and Asus ROG Ramdisk are still reasonably fast nevertheless, though certainly not always, as the speed tends to vary a lot depending on what settings you use with these two, which is kind of a bummer actually. But anyway. Dynamic Memory Management and Compact Mode are why Primo Ramdisk really mops the floor with them. When it comes to sustained sequential read/write performance, all the other choices also including all the ones that are not free either are slower or are not much faster than PCIe 4.0 speed. In that regard with only 16GB of 3200MHz DDR-4 in my grocery store laptop that is already more than two years old I get double the read speed and quadruple the write speed of the 2TB WD Black SN850X SSD. Minus all the fan noise.
On a side note. Sandboxie-Plus writes data to a sandbox the location of which can be on a Ramdisk, and, not ALL of the unmodified data necessarily HAS to be stored in the sandbox. That is, only THOSE specific files that are modified by processes that run sandboxed always ARE copied to the sandbox, transparently by Sandboxie-Plus, so as to keep the original files always intact─which is the key purpose of running a sandbox. As a result it usually is possible to save even MORE additional RAM space than what already is possible with Dynamic Memory Management and Compact Mode. Some people run a whole VM on a Ramdisk so the whole OS gets stored in RAM. By contrast, I only selectively put data on a Ramdisk, only where doing so actually helps to improve real world performance. Any type of workflow that uses a Ramdisk consumes more RAM, therefore it makes perfectly good sense to avoid consuming more RAM than necessary, as much as possible, wherever it is possible to avoid. I use PrimoCache also in addition to Primo Ramdisk. But PrimoCache doesn’t let me choose what files I want to be cached in RAM. There used to be a time when Intel SRT (Smart Response Technology) was still more or less popular because you could cache your slow HDD by turning part of your SSD capacity into a cache with it. But you couldn’t choose what files you wanted to be cached with it so, I called it Stupid Response Technology. By contrast, Marvell HyperDuo did let you select the files to be included in the cache. Fundamenal differences can be found by people who care to search, and, just because the vast majority of people aren’t interested in them, doesn’t also mean that fundamental differences aren’t there. They are.
