I use RAM drives regularly so I know what maximum responsiveness feels like and no, you can't feel much difference between a RAM drive and a modern SSD,
RAM disks can't boost responsiveness in general Windows operations because the whole point of BOOT in computers is moving the data from storage drive to RAM, thus most is already in RAM anyways, which is much faster than what RAM Drive with software overhead can ever deliver.
An Optane NVMe drive is about same responsiveness as a RAM drive for this reason.
We went from random operation performance like 0.5 Read (MB/s) and 1.5 Write (MB/s) to something like 15-20 Read and 20-60 Write. In order to experience a similar jump, today we would need 200+ Reads and 600+ Writes for Q1T1 tests.
Even then it still won't feel as fast because you start being more limited by other parts of the system such as the CPU. Reading about Optane experiences, it sped up more "niche" parts of computing experiences, such as deleting large amounts of data, or even more niche such as running out of RAM and going on pagefile.
The real revolution would have been if they offered Optane DDR sticks on the consumer side and worked with Microsoft for "bootless" systems, and pushing software vendors towards loading directly from it.
Mostly when working on files like large Excel sheets (they get saved much quicker). Running portable apps on the RAM drive etc.
I think Linux does feel faster from a UI responsiveness perspective...
Linux is infinitely better in terms of security, bloat and how it handles updates, and even in the HDD days the structure is such you didn't need defragmentation.
Microsoft couldn't reliably update until about Windows XP. Windows 95, 98, and even XP a lot of times struggled to simply get updates completed. And it took hours upon hours and many restarts.
Linux? After giving it the command it finishes updates in no more than a minute. Doesn't ever need to restart.
Technically Linux is far superior. No wonder Android is a distant cousin of it. Microsoft's idea of a "mobile OS" with Win 8/10/11 is a skin on top of it, while Android's is a seamless one.
@mikeymikec Windows is basically officially approved spyware. It costs to have something that spies and collects data on users.
