I'm looking for a new M2 SSD for a secondary drive on my PC to store games and other large files on it. I found a bunch of these on Newegg in the 500-512 GB range all for the same price:

Newegg M2 SSDs

So I was particularly interested in the ADATA 512 GB one since for the same price it's 12 GB larger than the others. How big are these SSD's though? I know the actual storage space is different than what's advertised and I saw this listing on Amazon for another SSD advertised as 512 GB but then in parenthesis says 480 GB.

So with that in mind, is the ADATA SSD really bigger than all the other 500 GB SSD's? How much space is actually on each SSD? If the ADATA SSD is actually the same size as the others, then of that list of SSD's is there any particular one you all would recommend? Thanks!

No need to go for super fast Nvme drives if you don't need to.
I went from a standard SSD to a Samsung Pro, M2, and no difference in anything I do.
Technically faster, but reality no difference.
You don't need to spend a fortune on M2 speed, just buy one with good warranty and anything over 250Gb will last you a while and speaking of 500Gb will last very long time before being full.
Well, first if the ADATA has 512 GB and the others have 500 GB then you will get 12 GB more with the ADATA.
With that said, non of those are NVME SSD drives, they are just sata drives using the M.2 slot. For that there are only 2 brands i would ever consider, Samsung and Crucial, so out of the 4 you list I would personally grab the Crucial MX500, specially as they are priced the same.

So what would the downside be of using non NVME SSD's then and why would the other brands be even worse?

 
M.2 slots can connect in 2 ways, PCIE/NVME or SATA, the difference is speed.
The other drives are worse because they performe worse. With Sata drives pretty much every benchmark have shown the Samsung drives to be the best and the Crucial as a close up runner.
