I have a ROG MAXIMUS X HERO (WI-FI AC) motherboard. I currently have one 970 evo (1TB) and it works great. I wanted to add another one (a 2tb version) into the other m2 slot. Are there any problems with this? PC part picker says it should be fine but has this compatibility note on the bottom. "The motherboard M.2 slot #1 shares bandwidth with a SATA 6.0 Gb/s port. When the M.2 slot is populated, one SATA 6.0 Gb/s port is disabled." I am very new to pc building and have no idea if this would effect me. Any information on any potential problems with getting another 970 on my motherboard would be great. Thanks.

If all you're adding is that M.2 drive, you will not have any trouble. What that note means is that one of your regular SATA ports on the motherboard is disabled when the M.2 is populated, so if you tried to plug a SATA drive in to that port, it would not work. Refer to the motherboard spec sheet to find out which port would be disabled.

Thank you Jeff for the reply. I appreciate it. I assume a SATA port is whats populated using a normal HDD? Or perhaps an SSD?

Yes, that is correct, any traditional HDD or SSD drive that would plug in to the SATA ports. Looks like the M.2 only disables 1 of them though, so the other SATA ports will still work.

Thank you!

I am a bit confused. Does this mean that I can't run two M.2's? or that one of them would be slower because it is bottlenecked? I also noticed he is talking about the 970 pro and not the evo. Not sure if that would effect it at all.

You can run 2 NVMe m.2 drives in that motherboard. The m.2 slots are connected to the chipset (I didn't verify that, but it sounds plausible), and so if you have both NVMe drives running flat out, they might be able to swamp the chipset-to-CPU connection. They will run but there might be a slowdown. I defy anyone to actually measure any real effect outside of a disk speed benchmark, or maybe a terabyte database stress test.

Stick 'em in and don't worry about it!

(and yes, SATA is the kind of port that is used for a hard drive connection, or a traditional 2.5" SSD connection.)

Thank you, I think that ill just go ahead and buy it now as long as the speeds won't be effected very much.

Fantastic, thank you for the clarification. Assuming I will only be using the NVMe drives for gaming, I should be fine? Is getting another NVMe for gaming overkill as an SSD would be plenty fast? My current 1tb evo is great but the 2tb version is about $550, a pretty major expense compared to a 2TB ssd evo from samsung.

EDIT: Perhaps I should create a new thread for this question.

about the only time you will notice the NVMe speed vs SATA speed is when copying from NVMe drive to NVMe drive. Otherwise you probably would not even notice a difference really.

Samplebot submitter 1 point 2 months ago

So I would be wise to get an SSD for gaming?

Thank you for your feedback Flexo. It has helped me a lot. I am going to consider the 860 evo. It appears to be the same thing but last gen?
