Do 'ALL' motherboards disable SATA sockets when M.2 sockets used?

[Anomnomnomaly]

I built a new rig back in January, been building them for over 20yrs but the gap between my last one and this one was so long... that tech had really moved on. So one thing I wasn't aware of... that surprised and also really annoyed me... was that because I had 4 drives to go into the new rig + an NVME drive and a bluray/RW drive... (my car doesn't have music streaming built in (it has BT but it's phone only) and so I still like to fill up some CD's of MP3's for the 6 disc unit).

 

But using the M.2 slot disabled 2 of the SATA sockets... and I wasn't aware of this at all (my first board with M.2)... and with 4 drives (2x 1TB SSD + 2x 3TB HDD), it means my optical drive cannot be plugged in unless I buy a PCI-E Sata card. I had to go back and dig through the manual to find out this was supposed to happen.

 

 

However... this was only a temp build for gaming and daily use.  One of my other systems, a mediaserver is still running windows 7 and will need to be upgraded by Jan... So I figured I'd swap out the motherboard/cpu/ram into the new system and clone the OS drive from the NVME onto a new SSD for that system (current OS drive is only 250GB) as I have 30TB of storage across 6 drives... so will need all of those SATA sockets free.

 

 

The new gaming rig will be an X570 board and a ryzen 3xxx series once they're out.... But I don't want to make the same mistake... and I can't find out for certain on manufacturer websites if the current X470 boards do the same thing.

 

 

So my options will be to get a board with at least 8 SATA sockets to compensate for losing 2 with an M.2 drive, or a board that doesn't disable SATA sockets when using an M.2 drive... and I cannot find out for certain that ALL boards don't do this. Or if I just need one with more lanes to allow both types to be used at the same time.

 

 

 

I know X570 boards aren't out yet, but aside from PCI-E 4.0 and some minor tweaks they're going to be pretty much the same as current X470 ones... So are there any current boards that meet my requirements, so I can double check any X570 version when they come out later this year.

I searched for this myself, wanted a ton of SATA ports and my PCIe SSD, but no dice I'm afraid. However, the fact that it "disables" SATA ports isn't entirely true, my current board merely allows them to share bandwidth. It's really hard to find out when certain boards do this, when they are all purported to disable the ports.

Some boards dont, notable x470.

check my X570 list for more info when more details are announced. X370 taichi has 10 sata ports (!)

Some boards have extra sata controllers.

The 2 sata ports disabled thing i believe it's a limitation due to the small number of pci-e lanes chipset creates (i think 8 for x470, 5 or 6 for b450)

 

An option would be Threadripper... 64 pci-e (4 to chipset, 60 pci-e lanes to slots and m.2)

 

ex.

 

300$ for 1900x : https://www.newegg.com/Product/Product.aspx?Item=N82E16819113457

(cheaper in other places)

250$ ASRock X399 Phantom Gaming 6 sTR4 AMD X399 SATA 6Gb/s USB 3.1 ATX AMD Motherboard

8 sata + 3 x m.2 nvme + pci-e x8/x16 to plug 4 x m.2 adapter cards in

 

+ cooler

 

Alternatively, there are sata controller cards/ hba cards to add more ports

Amd has 4x dedicated from cpu for m.2

Yes, the first m.2 has 4 pci-e lanes from cpu.

The 2nd m.2 slot has pci-e lanes from chipset, though. If nvme drive is inserted in this, some sata may be disabled.

there are boards with 8 SATA ports natively plus an M.2 port that doesn't affect SATA ports at all. In fact many high end Ryzen boards can use multiple PCIe M.2 drives without shutting off SATA ports, while Intel boards usually support 1 PCIe M.2 without cutting SATA port only.
