M.2 SSD Compatibility: why so weird?

Hey everyone,

i'm hoping to seek advice about some strange issue i confronted a week ago: Sorry for all the text, i dont want to skip out information.
Anyway, I bought the new Samsung 960 EVO 250GB SSD because I didnt want to bottleneck the new PC i was building for video editing.

About a month before that, i got myself the Asrock Deskmini 110, which also had a M.2 slot. There, (learning by doing) i managed to buy a SATA SSD for a PCIe-run slot, therefore making the SSD incompatible with the Deskminis motherboard. Okay cool, different hardware, learned from that so i sent it back.
Two weeks ago, i started looking for M.2 drives that could fit to the Asrock X99e-itx/ac motherboard, which supports both SATA and PCIe (and NVMe) M.2 SSDs. So i thought, why not go with the 960 evo, because it was the cheapest gb/dollar and had by far the best performance.

When it arrived, it neither popped up in the windows installation menu nor in the BIOS. Yes, i tried using CMS and Launch Storage OpROM Policy in UEFI Mode, i updated and resetted the mobo a few times, tried to load drivers and even swapped the SSD into the Deskmini just to see it appear in the BIOS (so it works), checked, whether it was well within the socket as well as for the skrew etc. nothing.

->Why aren't all motherboards compatible with all SSDs of the same technology? I didnt have to run any BIOS update on my Deskmini to see the Samsung 960 in the BIOS.
I am not willing to spend more money for a predecessor SSD with worse read/write speeds and IOPS. I do video editing and CAD design and therefore really want to use the 960s, if possible.

Since it is merely a software problem, can one fix that or am i really forced to get some of these shitty SSDs? Dont want to send it back, otherwise I would be aiming for 250GB SSDs at the same performance, preferably not twice the price.

Thank you very much, i have already wasted hours trying to solve this, searching through forums and contacting support.

PS: i dont think the mobo is broken, but i cant give a guarantee on that...

Nope, not yet.

Bought myself a 2,5" SATA SSD to get this PC running, and when Asrock might add a BIOS update, i gonna use the 960.
I've read that the M.2 deactivates some lanes, but not in this case :/

The m.2 has to because it uses the Sata lanes. Unless your motherboard for some reason has dedicated lanes to communicate with the m.2 or you're using a PCIe expansion card with an m.2 slot, it will disable usually the 1st slot, or a combo of the 5th and 6th together based on which slot and which mode you're in.

Thats why i dont have anything plugged to the SATA ports.

The problem is, that through the BIOS, the motherboard only approves a handful of disks that are listed on their webpage. Other motherboards simply support any drive that fits the socket... is that applicable to any mobo though? And why NOT?

Hi, thank you Stapler for trying to help.

So, the mobo supports the Samsung SM951 drives, predecessors to the 960 whihc are NVMe too. SO yeah, the mobo DOES support NVMe drives. And yes, BIOS is fully updated.

Im not trying to get help, unless i really dont manage to solve the problem myself ;)

Cheers, Atten
