Thimphu Motherboard - Which SSD ports are disabled using M3 keyed M.2 Drive? No Manual?

[Hahacharade]

There's no manual for my Motherboard below.  It has 5 SATA slots per the linked picture.  Anyone know which ones are disabled by M.2 use?  This would really help me out!  Trying to get this drive (Crucial P1 1TB 3D NAND NVMe PCIe Internal SSD, up to 2000MB/s - CT1000P1SSD8) but I have SATA drives in use already, so I want to ensure I plug them into the non-disabled ports.

Hello
why the SAta ports were they disabled?
I've never heard of this ...

[Hahacharade]

It was my understanding that if an M.2 drive was used (regardless if it is NVMe or SATA) 1 to 2 SATA ports will be disabled on a given  motherboard. In regards to the motherboard I posted below, I’m not sure if it’s specific ports or just ports not used. It’s all over google if you search m.2 drive disables SATA. I just wish I had a manual to show which ports if this is the case. It has to do with PCIe and SATA sharing lanes or whatever

I haven't searched yet!
i am using a pc with an m2 and two hard drives connected, plus the dvd player, i cannot test all the locations, but it seems unlikely to me ..
This type of manual will not be found here
Find the compatible m2 already, that will already be a good thing!

and if you see this :

there would be the possibility of a maximum of three hard drive

Yeah I’d really like to get one but I have 3 SATA drives. I need to know what ports to use I guess?

as i told you, there is no information about it here!
Afterwards if you have the discs and don't need to buy them, you just have to try!
