Redstone 5 was when it got changed but it's still used although instead of calling it Superfetch it's back to being named the same as the service itself so it's called "SysMain" now both under Services and the Task Manager.
You can see it spin up every so often so it's pretty easy to spot and with the cache function from Redstone 4 (Creators Update.) it'll also run every time you exit a program as it works it into the cache which under the task manager and memory you should see it divided between "In use" "Modified" "Standby" and "Free" with standby being the cached data.
There's tools for more thorough viewing of exactly what is cached in the standby memory but when it's required the OS can dump this data or you can empty the data yourself such as with the earlier listed utility or other programs though super fetch should start up immediately to re-optimize the cache memory for any current running software.
Earlier the standby memory tended to consume almost all available RAM but after the recent updates it seems to be capped to always leave a part of free memory and it also unloads earlier allowing other running programs to use RAM as needed although I don't know if that's specific to Redstone 5 or if it's been included in the newer cumulative updates for Redstone 4 too by this point so the various software for emptying out this data might still give a performance increase if there's still any issues with how this is cached or how the cache is handled.
Well bit of a longer post but even using a SSD Windows 10 should still retain super fetch and with the stand-by memory and using RAM as a cache it should still allow for a speed-up for any subsequent starts of a software as long as the data is still retained in RAM and hasn't been unloaded though I can see this also skewing testing and benchmarking unless the data is emptied out first.
As for QLC and SSD's I'm glad to see alternatives for storage space and affordability even if QLC brings additional restrictions over TLC though for regular usage it's probably not going to wear out or slow down notably and should still have a edge over a traditional HDD in most cases though I have to do more reading about this so I'm not particularly well versed in how this all works myself so it's something to look up for the next major system build I suppose.
Hmm wonder if PCIE 4.0 and something like Optane would be able to compete with DDR but then we also have high-speed DDR4 now and triple and quad channel memory so probably not, only problem here is between AMD and Intel and getting the kits stable on respective hardware but it sounds like AMD has made several improvements already. Well that's not hitting consumer grade hardware just yet I suppose and then devices that could really benefit from PCIE 4.0 and current devices are already capable of hitting Gigabyte speeds.
(And improvements on a OS level and software in general taking advantage of high-speed storage devices like SSD's more thoroughly, guess that's also going to be a thing but with time it should improve further.)

Review: Samsung 860 QVO 2TB SSD (QLC NAND)
Hey HH, do you think reliability of big SSDs is enough to assume we can ditch HDDs for gaming purposes (instantaneous textures streaming and blazing fast loading) and keep them for pure storage only?

Part of Redstone 4 and the cache to RAM I guess, for a larger game you can see superfetch kicking in via the task manager after you exit and it begins filling up RAM to it should be around 80% or so depending on how much data it can fit and then leaving a little bit of entirely free space left.
Successive runs will then be much faster using the cache data but it's possible to empty out the "stand-by" memory now cached via for example this.

Superfetch is deprecated--can't remember when the superfetch service was removed, but it was a while ago. The newer caching scheme (I'm on 1809, build 17763.134) seems to handle things a bit differently. I think I even posted to these forums about it when I noticed it Superfetch was no more.
