How does SSD "memory" works ?

Optane cache thingies are supposed to do what you're thinking of. If the motherboard supports in, the Optane module can sit between cpu and a SSD and "listen" to the requests from SSD and pass them through, and over time the Optane module is supposed to "learn" what the operating system requests more often ( some DLL libraries, some files, some executables etc) and copies them to the Optane memory. Then, next time the Optane module gets a request from the operating system it cached, it detects that and instead of reading the files from the mechanical drive or SSD, it just serves the data from the Optane module.

This is supposed to accelerate systems that have mechanical drives, less SSDs which can already serve files super fast.

 

A SSD is a "dumb" device, it simply serves data as the operating system requests it, just like a mechanical drive. But, because it uses memory chips, the requests are served super fast, as there's no latency (on mechanical drives, disc needs to spin and the read/write heads need to position over a particular track and then track needs to be read in the drive's cache memory and then served only the portion the operating system wanted and so on) and the SSD controller can read and write data from multiple memory chips at the same time (like processor can work with memory in dual, triple or quad channel to speed up transfers, ssd controllers typically work with 4 or 8 chips in parallel)

I'm a noob, aright ? Please bear with me.

 

As far as i know, the SSD learns which software you are using the most and so it makes it start up and run faster. So does that carry over different windows installations ?

Say you have a win10 running and you are using Adobe Premier frequently so the SSD learns that. If you install a fresh win10 and Premier again, does the SSD still remember that you use Premier ? Or it will start recognizing your pattern all over ?
