Since this is my first upgrade in quite a while moving from the FX-8350 to a Ryzen. I have a few questions about the M.2 SSD units before I go and get some for the system.
I understand these all sit on the PCI-E buss lanes. I know in the old days, running something like SLI or Crossfire would cause the PCI-E slots to downgrade to the lowest slots speed. SO if you did not have all 16x slots, you might end up with both running at 8x as the lower slot had this speed.
Is this something I would see on the Asus X470 TUF? I know this may seem like a silly question today, but its a new tech to me while trying to avoid an old issue.

not an issue with new gear, buy and enjoy the blistering speeds... I love mine. can never go back to an SSD for an OS Drive... Vin
EDIT: Oh, I just used the intel version that board on a build for someone... nice board.
EDIT2: oh, 1 thing to consider, some boards have two M.2 slots, sometimes a slot can share the SATA connector lanes. Then usually you then lose the ability to use SATA 0 and 1... that's all I can think of

As an example between such the standard Z170 OCF has three of these slots, my Sabertooth 3.0 has only one.
It does make a difference but not enough to worry about, m.2 drives are lightning fast once set up.
The downside is Win 10 is the only OS currently that has drivers for these included, to make an older OS such as Win 7 to work it takes alot of work and even then there are no guarantees. I've yet to make the one I have work with Win 7 so I don't use it, I did load Win 10 on it because of that to see how it works and it's just crazy fast, screams when booting up and such.
However.....
Personally speaking I will not run Win 10 and since I don't game online or just much at all so it's nothing for me to be concerned about anyway.

Awesome thank you. This board does have two slots but they are labeled as M.2_2 and M.2_3 respectively for slots. I am assuming this means they are separated from the other lanes then?
The motherboard looks and feels fantastic. I was hesitant at first with the slightly fewer VRMs but the reviews said this new design doesn't need as many, so I gave it a chance and really like it. The settings aren't as diverse as the CHVII but that's fine, I do not appear to be limited by this at all with my hardware and clocking.
Guess we will see how she handles a pair of M.2 drives and another set of memory installed. Then I just wait for the next gen AMD cpus and I am set for a while. I get to finally play with my memory clocks once I reinstall tonight!

I believe it will do fine, you probrably won't see anything you woudn't like from it.
Yes I too believe the lanes for each slot are divided, note the placement of the slots on the board itself - Not that placement in itself means anything but probrably to do just that, split up the allocation of what lanes the slots tap into to function.
At least that's what I'd think but I'm probrably wrong about that I'll admit.
Regardless, go for it and let us know how it does for you.

Ok, now I am getting really confused looking at this. So go check out the website I linked. It says the top one is from the CPU (M.2_1), and the bottom one is from the PCH (M.2_2).
Um a PCH is an Intel part... and if the top one is to the CPU that would make it the real PCI-E interface as the other below would be chipset limited to SATA. The documentation, the website, and everything is confusing me on which slot to use for my OS now lol.

Here is the X470 block diagram this is what you get. Any extras are just speed limited add ons by the board manufacturer. PCH (peripheral controller hub) is what the X470 chip is it isnt just limited to intel, you could call it southbridge but seeing as there is no northbridge thats a bit pointless.   |

I got her all figured out now and am currently reinstalling everything. I did not buy the extra set of memory yet as it spiked in price again. I can wait a little and see if it comes back down again. No big deal for that.
Pulled the trigger on some Samsung 970 M.2 units and am excited to get it all up and running again!

So far I really like the M.2 drives. It was not as day/night coming from a HDD to SSD used to feel though.
However there was a very interesting result which was unexpected by me. I installed the OS on the M.2 drive and put Anthem on the mass storage SSD group. Instead of having it on the same drive as the OS. Load times despite being on the same quality SSD as before have been cut in half.
Is this simply because the OS is now directly linked to the CPU via PCI-E lanes and freeing up action on the SATA controller? Basically the page file and all other misc operations would no longer be sharing the controller correct?

Nope, it's the speed you didn't notice... the M.2 drive is faster. to get similar speeds you would need 4+ SSD's on a raid 0 (Stripe) and a reputable RAID controller.... quite costly...
for example..
HDD speeds ~10-60mb/s (if a good drive ~100mb/s)
SSD Speeds ~120-400mb/s (SATA3)
M.2 Speeds ~1800-3200mb/s
going from an HDD to SSD you can get up to 10x to 40x of a performance boost... but going from SSD to M.2 you only get 5x-10x depending on file size and system load. So the change isn't as big, so it isn't as noticeable.
but all the background stuff that happens, now happens faster. Caching is faster which would help that load time.

I get what your saying, I am saying though its weird because the game that is loading, is installed to the same SSD as before, an MX500. It is not on the M.2 with my OS. This is why there is confusion, the load times feel crazy fast to before when the game was installed to the same MX500 as the OS.
Unless of course I am misreading what your trying to convey.

I'd guess that the caching for the game is done on C-Drive and not at the Game Drive. just like your page-file and other temporary files for the game.
