I'm reading about the sata ports and m.2 conflicts with all manufacturers.
I have two m.2 sata SSD and 6 sata ports coming out of my drives.
Now I was hoping to move to z270 system but the max number of sata ports are 6 when compared to all brands and each manufacturer explicitly details when using either m.2 ports 1 or 5&6 will be disabled because of sharing lanes.
Now what could I do to ensure I use both m.2 sata SSD and all sata ports?
Suggestions?

Is this because Intel keep releasing 16-lane CPUs rather than the 40 lanes they used to have on most chips?

This is more or less why I went with the X99. 40 real lanes, plus more 2.0 lanes plus 10 native 6G ports. I don't really like the trend of reducing storage options.

Perhaps the upcoming Intel X299 (Socket LGA 2066) motherboards would be a better choice, as they probably won't have this limit (X99 doesn't have this limitation either). It says here they should be released in the second half of 2017: http://ocaholic.ch/module...icle.php?storyid=15669

+1 on this. Skylake-X might be better but that all depends on how many resources are being shared on the motherboard.

The z270 Classified K has 8 SATA ports, 4 off the chipset plus four off a Marvell controller, and only two of which are shared with an M.2 slot (2/3 are shared with the 80mm slot).
The 110mm M.2 slot is shared only with the U.2 port so won't conflict.
If you're just worried about plugging in 6 SATA devices and two M.2 devices, then the Z270 Classified K would work.

Nice find Airwolf!
Unfortunately yes, this is commonplace for Z270 boards. If ya really need that many SATA / M.2 ports then you will probably want X299 to avoid the problem. Or wait for ASRock to develop something, they've been known to add additional chips and go crazy with the port offerings on some models.

I am praying that the new CPU is not locked down to Only Windows 10 on the X299 Platform.

The Kaby Lake CPU provides 16 lanes, the Z270 chipset provides 14 lanes (as opposed to the Z170 having 10 lanes I think). more info.

Yes thank you that helped. Got my gear setup and fired!!! All sata ports work flawless with M.2 SSD installed. Thank you guys... one more thing Z170 boards blow chunks!!!!

I know how you feel. To do my upcoming Z270 build I'm going to have to leave my beloved 7 behind. But then again, isn't 10 designed to work better with the latest chips? What about DX?

thanks :), also on the 270 FTW-K manual doesn't say what the M.2 shares when in PCI-E mode but I probably think from the chipset

Z270 Classified is wired quite differently from Z270 FTW. In the Classified: If you use the 80/110mm m.2 port (basically sits under your GPU in PCIe slot 1) then that one conflicts only with the u.2 port, so you're good to go on that unless you're using a u.2 drive (which are expensive as hell), and all 4 of your SATA ports will be good to go as well (or more if you want to use Marvell...) The 80mm m.2 lower port conflicts with SATA ports 2 & 3 (or all PCI-express SATA), so if you use that lower m.2 port, you are limited to only SATA ports 0 and 1 ...unless you activate the Marvell SATA ports, which most people want to avoid, lol. I usually use a primary SSD for the o/s, a second for games, a third for media and all sorts of crap I don't access as much, then a fourth mech drive for backup. My question for any EVGA tech looking at this : the m.2 Samsung 960 Pro has awesome speed BUT they will throttle when put under a heavy load. When that happens, the speed of the drive is greatly reduced and in a worst case situation may even end up slower than a standard SATA-based SSD due to their thermal management measures ( link). If I plonk a 960 Pro in the m.2 port under the top GPU (in the Z270 Classified), I would think it's going to get pretty toasty under there, and may result on throttling ...but if I move it to the lower m.2 slot where it's a bit cooler (I'm not going to run SLI), I knock out SATA ports 2 and 3, limiting my options or having to turn on the Marvell SATA ports... which I'd prefer not to do. Has EVGA done any testing on how hot a Samsung Pro in that upper m.2 port may get with a GPU covering it? Ideally I would have done it the other way around, since I doubt I'll be using u.2 but I'd usually use 3 SATA ports plus 1 m.2 port... but that's just me.

I'm not a evga tech, but i did see they make m.2 to u.2 adapters. You could just move the 960 pro to a drive bay that's near a case fan thus giving it proper ventilation. The adapter i'm talking about is something like this: While m.2 is neat since it goes on the motherboards and it's great for compact builds, placement and heat will always be an issue.

If you don't mind paying like $40-52 for that adapter. I wonder if small passive heat sinks would help reduce throttling. Is there enough clearance to avoid blocking the GPU from latching and sit down all the way. It could be a pain to remove the heat sink, if you ever need to do a RMA.

Honestly wouldn't having a reference GPU over the m.2 drive help with cooling it? I mean for cards with a blower style fan? The blower fan would, at least in theory, draw cool air over the IHS of the m.2 drive and exhaust the warmer air away from the drive, helping to cool it.
Of course that only applies to blower style cards, but still.

"To put this into perspective, since the 960 Pro took 130 seconds to throttle and has a sequential read speed of ~3.5 GB/s, you should be able to read about 455 GB worth of data at full speed before the 960 Pro throttles down to "only" ~2.6 GB/s." I mean is that really an issue you will ever run into with desktop usage? And no, none of their scenarios show slower than SATA drives.

Yes. It will be an issue I run into in 40 years when I'm watching my uncompressed 16k480fps HDR20 videos, okay? XD

Another option is to use this Asus board Z270-WS, its not released yet and no info on pricing.
Hdmi 2.0, quad SLI, 1 x M.2 x4 Socket 3, with M key, type 2242/2260/2280/22110 storage devices support (PCIE 3.0 x 4 mode)
Looks promising
