new pc need help

I can't answer all your questions but I'll touch on what I can.
It seems to me a strange storage configuration. 2 HDD and one SSD. I would have to assume that the configuration would be set up idealy straight from the factory. It seems to me changing the configuration would require a new install, which doesn't seem worth it unless you're running intensive programs such as gaming at high settings, video editing, etc... but for regular day to day use, or even light gaming I wouldn't worry about changing it.

I have been using laptops for years. Mostly 17 in desktop replacements. A little over a year ago I bought a new laptop expecting it to be better than anything I've ever owned. It's not. I have had frequent bottlenecks in memory and often habe to log out and back in to do any gaming, something I've never had to do in 10+ years of laptops.
I suspect a big culprit is Windows 10. It seems to be a drain, not to mention Extremely intrusive trying to find ways to grab as much personal info as possible from as many different sources as they could figure out.
Of you want to move your media to another drive then it should be a matter of simply moving them and having your media player default to the new location.
When you say security I guess you mean antivirus and such? That would require you to uninstall and reinstall to move. I don't see any reason to do so, though.

As far as your processor questions I could wager some guesses but I'll skip the speculation and allow morw informed people to provide facts.

thanks for the reply ug. i had this system built by a guy, its not factory. and i also didnt get the 2 HDDs.
i dont do a lot of gaming but i do like to move big chunks of files fast, and this system so far is less than what i was expecting on speed.
i upgraded to w10 last year on one of the laptops at home and hated it. after about 6 months i put 7 back on it. w10 seems to be geared more to tablets and touchscreens.
security is avg/malewarebytes/spybot. i used to have zonealarm but thnking of trying out comodo. i also want to replace avg with kaspercy, but still dont know how it stacks with MB and SB, they work really well with avg.

Ah, you said a c and l drive, I assumed two HDDs.

Malware bytes is, or used to be, not sure how, a top free anti-malware software. So it's not a matter of working well together since it performs a different function than antivirus.

My laptop came with w10, so I'm stuck. Outside of a few nice improvements that should've been done long before w10 I hate it.

But HDD is slower than SSD. One is a physical drive, the other is basically just large memory. Without having the limitations of a physical functioning the SSD is faster.

First, file copying speed is not an indication of "how fast my computer is." That's just a measure of how fast your hard drives are, minus overhead for file verification. Different things your computer does will operate at different speeds, depending on what you are doing and what hardware is being used.

If your Windows system is installed on an HDD and you want it on the SDD you can simply clone it from one drive to the other. I've done that for years - I even make a practice of resizing a new computer's Windows to about 63-ish gigabytes, cloning it to a 64-gig flash drive and then expanding the computer's Windows partition back. If I ever royally mess up something on the computer I can just wipe it out and clone back from the flash drive. It has saved my bacon more than once. Cloning is easy and there are many freeware utilities for cloning, including image disks you can burn.

But unless you are a hardcore gamer I probably wouldn't advise messing with the setup. If it works for what you need the computer to do, that is what matters.

Again, please don't judge your computer's speed by how long it took to shift files. That usually doesn't have anything to do with the speed of the processor and RAM. A slow computer can copy files real fast if it is connected through a USB-C connection to really fast external hard drives. A fast computer might copy files slowly if you stick an old USB 1.1 flash drive in it.
