BIOS not recognizing my SSD (plugged directly onto the motherboard using NVMe to SATA adapter)

[ereboreum]

Hi,

My workstation has 4 drive bays, two of which is occupied (one boot drive SSD & one storage HDD). I wanted to add two more SSD drives to the two empty bays using NVMe to SATA adapters <https://www.amazon.com/StarTech-com-M-2-2-5in-SATA-Adapter/dp/B00ITJ7U20/ref=sr_1_3?crid=26RC55DT2SO...>. 

The issue is my BIOS is not recognizing my SSD drives that I installed using the NVMe to SATA adapters. 

Here are all the things, I have tried:

1. The NVMe to SATA adapters are working; I tried it in another desktop.
2. My NVMe SSDs are working. I tried it in other devices.
3. There is no cable involved to check for weak connections - I am directly plugging in into the SATA slots.
4. My BIOS drivers are up to date.
5. BIOS disk options set to IDE.
6. BIOS hard reset by draining my battery.
7. Disk management doesn't show the drives.

Any advise on how to resolve this issue?

Hi Ereboreum,

Looking at the desciption of the M2/SATA SSD adapter you mention,

Not all M2 drives are the same, e.g. NVMe, AHCI and SATA III are not the same, or interchangeable. Your adapter card does not support NVMe drives! You need to be using a M2 SATA III drive similar to these;

EDIT - It sounds like you may have already purchased the NVMe drives? You can still use these drives as data drives in your Z820 but you would need to purchase a couple of M.2 PCIe adapter cards. This is assuming you have 2 free PCIe slots to accommodate the drives?
