Samsung SM951 M.2 -- a bit of confusion

I'm building my dad a computer. I have used the Samsung SM951 M.2 SSDs in a couple of previous builds and have been happy with them. On those, I just used the 128 GB version for the OS and a few applications storage. They are getting harder to find on Newegg though. I want to keep it a bit simpler for my dad, and not have him needing to navigate to various drives. I thought I would just use a 528 GB SSD so he would only see a C: drive, as that is what he is used to. I think that much storage will last him a long time. He typically surfs, uses FB and does some genealogy. So, in my search I found one at Newegg, for $379.95. Also, I found one on Ebay for quite a bit less.

I have noticed that on all of the SM 951 SSDs that Newegg sells, they have whited out the part numbers, serial numbers, model numbers, and anything else that can identify exactly what the product is in the pictures. In the description for the Newegg product, it identifies it as part number MZHPV512HDGL-0000. The Ebay product number is MZVPV512HDGL-0000. What is the difference between these two drives? I believe what I am looking for is the NVMe drive. In the screenshots of the benchmark testing on the Ebay product, it identifies it as NVMe. The description in the Newegg product says "Samsung SM951 M.2 SSD (AHCI model)". Does that mean "not NVMe"?

It's been a year or maybe even two since I've built a computer, and I though at the time that what I got was the best thing going. I did buy my first SM 951 from Ebay, as Newegg didn't have what I was looking for. I don't know what the newest and bestest thing out there is anymore. I have no clue about the 950 Pro M.2's.

The components for this build can be found here.

I am open to other options, and all suggestions are appreciated. So far I have only bought the case, motherboard, RAM, PSU and CPU cooler.

Thanks!
 
AHCI would indeed mean, not NVMe. Both AHCI and the newer NVMe do the same thing (specify how information is moved between drive and host system), and a certain drive will use one or the other. Even some m.2 drives that connect via PCIe still communicate via AHCI. From a quick google, AHCI vs NVMe is indeed the difference here.

I may be too late in asking this -- the description from the motherboard (which I already have) says "1 x M.2 Socket 3 with M key, type 2242*/2260/2280 storage devices support (both SATA & PCIE x4 mode)". Will all of these M.2's mentioned above be compatible? I don't want to buy an M.2 that will be limited by the mobo.
 
What model is the board? Generally, if it's Intel 10 series (Z170/H170, etc) for use with a 6th gen chip it supports NVMe. My board is an ASRock H170 board (i5-6600) which works perfectly with the PM951 NVMe.

ETA: your partpicker link isn't correct (you need the "permalink" with the random-looking string of digits in it)

It's an ASUS ROG B150I PRO GAMING/WIFI/AURA. So it's an Intel B150. Probably way more than my dad needs, but I wante built in wifi in a mini itx board. I didn't want the big black antennas in the back, and I'm partial to ASUS boards, for no particular reason.

OK, good. Thanks. As for the ASUS QVL, I know that they can't test every single component. They specify the MZ-HPV5120-512GB for AHCI, and the MZ-VPV1280-128GB for NVMe mode. I'm assuming that the MZ-VPV512XXXX (512GB) will work as well.
