This one is AHCI: https://www.amazon.co.uk/dp/B01I5GZV9A/?tag=tonymacx86-21

You won't need the PCI-e adaptor, so just pull the SSD from it.

Is there a comprehensive list for AHCI M.2 drives, I am having a very hard time find any but 1 and it's only 128GB I was hoping to find one with 256GB minimum.

Nevermind, I found one on NewEgg http://www.newegg.com/Product/Product.aspx?Item=9SIA12K45Z3851

This one is from the Builder's Guide, my fault. http://www.newegg.com/Product/Product.aspx?Item=9SIA12K3G96790

Sorry, I'm unaware of any lists. All the reports I've read from Mac users have used Samsung M.2 SSDs or Apple SSDs. Samsung's SM941 and SM951 both come in AHCI but the SM941 is older and slower than the SM951. The Apple SSDs used from 2013 to present are all AHCI but, to use them on PC motherboards, an adaptor is needed. Here's the adaptor that I use in my system:

The following is a very comprehensive thread on using AHCI M.2 drives in real Mac Pros. But the information is relevant to hackintosh users too.

Would it be faster (in terms of real world usage) to have a single SM951 256 GB m.2 SSD or two individual 128GB 850 Pros in raid 0? Does macOS even support raid setups?

Just to clear up some possible confusion, in the image provided previously by pastrychef the number at the end of the model code (circled) indicates the drives capacity. It is only the beginning that should be of any concern.

MZ-VPV = NVMe drive

MZ-HPV = AHCI drive
