3x samsung 970 EVO 1TB M.2 2280 in my mobo

[Kigiin]

I need some help to confirm this will work.

 

I have  Gigabyte Z390 AORUS XTREME EATX LGA1151 Motherboard

 

I have 3x

Samsung 970 Evo 1 TB M.2-2280 NVME Solid State Drive

If I put all three in the mobo, will everything run smooth?

 

Thank you for your time.

Just off the bat, I wouldn't recommend doing that. Each SSD would take 4 PCIe lanes, so there goes 16 of your 24 PCIe lanes. Leaving you with 8 for the chipset and whatever PCIe devices such as a GPU.

 

All three of the slots support M.2-2280 PCIe SSDs. So for those alone, yes, it will work. (They also support SATA SSDs, so if you're willing to drop to something like 860 Evos, then you can gain some PCIe lanes back. I'm pretty sure this will disable all 6 SATA ports though.)

 

The first PCIe x16 slot runs at x16 and shares bandwidth with the second PCIe x16 slot. Runs at x8 when the second slot is populated.

 

The second PCIe x16 slot runs at x8.

 

The third PCIe x16 runs at x4 and shares bandwidth with the M2P connector (the smallest of the 3 M.2 slots), and runs at up to x2 when a PCIe SSD is installed in that M2P connector.

Would 2x M.2 and 1x Samsung 860 SATA SSD be better?

Possibly, or even 2x 860 Evo or 860 Pro and 1x 970 Evo. Just make sure that the smallest M.2 slot (the M2P slot) is filled with a PCIe SSD, since it doesn't support SATA SSDs. All the other slots support both PCIe and SATA SSDs.)

 

There really isn't much noticeable difference between SATA and NVMe SSDs. You'd see maybe a few seconds difference in Windows boot times, but other than that, it won't be very noticeable outside of file transfers between two NVMe SSDs. (Unless you're doing stuff with very read/write heavy workloads, like 4K video editing.)

So then I should be fine all around with 1x M.2 in the M2P and 2x 860EVO SATA SSD. Have my operating system on the M.2 with everything else on the SATA SSDs?

 

I plan on running duel GPUs in the future.

If you want to do a dual GPU setup, you'd definitely want the 2x 860 EVO drives and then the 1x 970 EVO drive, that way you've got at least 8 PCIe lanes free for each GPU. And yep, you should be able to put the OS on any of the SSDs.

 

Note: I wouldn't recommend dual GPU if you're planning on using it for gaming. The support for it really isn't there to justify the cost. More often than not, you'll see no benefit from it, or maybe even worse performance because of it.

the cpu  pcie lanes are seprate from the chipset lanes, so you can run 3x pcie ssds in m.2s and dual gpus without an issue. You will be limited by dmi speed for the drives though

 

But OP, just get one or two bigger ssds, why so many drives.

Thanks a lot of taking the time to help me.

 

Ok, quick run down just to confirm I fully understand (I dont want to goof this up).

I can run 2x M.2 and a SATA SSD with 1x GPU and I should be golden or, I can run 1x M.2 and 2x SATA SSD if I want to do duel GPU?

 

I have the M.2s so I would like to utilize as many as I can without negatively affecting the PC.

 

Thank you for the advice about the GPU. I figured such so I'll stick to just one GPU.

 

Thanks again for your time and patience.

Honestly because I have them. I currently have 3x M.2 970 EVO and 1x 860 SATA SSD. I just want to utilize whats best.

I'm not sure how PCIe lanes are divvied up by the board when you've got PCIe SSDs running in the first two M.2 slots, so I can't say for sure, though I'd assume 2x NVMe and 1x SATA SSDs would still let you use the first PCIe slot at at least x8.

 

If you tried all 3, you might end up with the GPU running at x4, which may harm performance (not entirely sure on that). I don't know how many lanes the chipset eats up, or if there's anything else (like a wifi card) built in that might eat some up too.

 

If you already have the three NVMe drives, go ahead and try two, or maybe even all three of them. If it doesn't work, then swap one or two out with SATA drives.

Nope, it's totally fine.  Chipset =/= CPU lanes

Look, before dropping authoritative statements all over the place you could at least google the mobo and take a look at listed specs.  Don't spread misinformation because you don't know and can't be bothered to do the research

the top pcie slots are cpu pcie lanes, so it won't be affected by whats in the m.2 slots.

m.2 are running off chipset lanes, top 2 x16 slots are running off cpu lanes, they won't affect each other. the gpu won't to x4 no matter what

what not just try it?

 

But if you got the drives, might aswell run them all you got the slots for it.

Thank you all for your help.
