Hi All,
Receiving my Z390 FTW and building a new rig from the ground up.
It's been a while since I've built anything as my current machine is very old, and I was wondering if I will run into any bandwidth issues on my two NVMe Samsung 970 Pro drives when paired with this motherboard and the 9900k. Someone suggested that the number of pci lanes with this combination will result in me only getting half of the maximum data transfer speed that these are capable of.
Before I return one of my drives, is anyone able to confirm that my setup will not allow for my intended use?
Thanks

You can use both drives. The CPU is only a 16 lane unit - which will pretty much be used up by the GPU Look at pages 15 and 21 of the manual PDF Page 21:
M.2 Lane Distribution
* M.2 Key-M (80mm, Top) – x4
o M.2 Enable/Disable is set within the BIOS
o This M.2 Key-M slot shares lanes with SATA ports 4/5. Installing an M.2 device will disable SATA ports 4/5.
* M.2 Key-M (110mm, Bottom) – x4
o M.2 Enable/Disable is set within the BIOS
* M.2 Key-E (32mm) – x1
o M.2 Enable/Disable is set within the BIOS
This motherboard does NOT have any lane replication via PLX; all lanes are native and derived from CPU or PCH. This also allows for improved backwards compatibility for Gen 2 devices.
Both of the M.2 will be ran through the PCH, if you had wanted direct CPU PCIe lanes you would have needed to go the X299 route

With the PCH link = DMI = 4x lanes to CPU the only time I could see there being a problem is if you were doing large file transfers between the 2 drives.
In reality how often are you going to do large data transfers from both drives at the same time?
Generally it is just game or workload files being pulled off of one drive into memory across the DMI link

Thank you all for the replies!
I was planning on using a 512 for OS and apps, and a 1TB for games. It sounds like this will not cause any bandwidth issues, and opting for one drive and creating a partition will not reap any benefits for my use.

I went with an 512gb 960pro as a primary / OS drive and an 1tb 970evo for games - works as a good combo If you somehow manage to run out of space and need that sweet M.2 NVME speed you could add an PCIe M.2 add in card to expand Just make sure whatever you get are not M.2 sata - you want the NVME drives

I am getting mine today and will also be making a complete new build using:
I9-9900k
EVGA DG-77 RGB Case
EVGA 1080Ti FTW GPU
EVGA 240mm AIO CPU RGB Cooler
Crucial 1TB NVMe in M2 slot 1 (Boot drive)
Crucial 512GB NVMe in M2 slot 2 (Game and video drive)
Crucial 2TB MX500 SATA drive for all my general data.
Corsair Vengeance 3000MHz ram, 32GB (4x8), RGB
Corsair RMX 850 Watt WHITE PSU with white cabling
I really want to see for myself if the M2 performance is as snappy as everyone says.
Hopefully I have no DOA's in the stuff I've accumulated.

I would be swapping those M.2 drives for the 512 as boot / OS and the 1tb for games and video I went this setup and my games drive is sitting at 610gb used up When games like ARK are using 126gb, GTAV 89gb, BF 1,4,5 all totaling to 200gb that space goes away fast

I debated that a lot......I'm going to go with your suggestion. Thanks for the feedback. Now I have to figure out how to get the system to" A) Recognize the M2_1 slot as a boot drive B) Let me install Ween-Doze on the doggone thing    I try to stay technically astute even at my "seasoned" age. Its a fun hobby that way. Want to see how this rig plays BF4 and BFV. Thanks again Da Old Dog

None of your pictures are working
As far getting the correct drive to act as the boot / OS drive disable the 1tb drive in the bios then install the OS

OK I disconnected all the drives but the one in the M2_2 slot. I got win 10 to install. ....but.....after about 5 minutes the system locks up hard and wont even repsond to the reset button. Note: Before I even before I installed the OS it would lock up on occasion while I was in the bios. I'll try pulling a set of the ram sticks and see if the lock ups cease.

I'd do a new install if your memory was off. I've seen where an install with improper memory configuration can corrupt the install.
might also set XMP profile on the memory.
