Z390 - Storage advice (PCIE lanes)

VincentHanna · 18 Oct 2018 at 11:31

I pre-ordered the Asus Maximus XI Hero WiFi at an okay price, so am waiting for my board.

I'm just considering my options in terms of maximising storage performance without saturating the PCIE channels.

I'll use 1x GPU (16x lanes)

I have a 1TB Samsung 970 Pro NVMe that I am planning to use (4x lanes)

Then I've got the option of either:

1x 512GB Samsung 950 Pro NVme + 4TB WD Black 3.5" SATA III
or
1x 512GB Samsung 850 Pro 2.5" SATA III + 4TB WD Black 3.5" SATA III

Are there enough lanes on the z390 to run 2x NVMe's and 1x SATA III drive?

The Intel site lists 24 lanes, which is why I wasn't sure.

That answers my question then, sounds like i'm best using just 1x NVME drive and then two SATAIII drives.

I think as I understand it 1x drive will run at full 4x M.2 NVME speed

And the rest will be limited to M.2 Sata speeds?

I was watching the MEG Godlike breakdown on GamersNexus Youtube last night, and it's pretty shocking considering the price.

But they mentioned other z390 boards have PLX chips for more lanes. Do we have confirmation anywhere which boards have PLX chips?
