Maybe that doesn't make it a bad comparison, but the SN850X is def intended to be a gaming part.

Gamers are the ones buying expensive parts so it makes sense to market to that. The next tier after this is basically server-class 10-20k machines which Apple is definitely not competing with (and SSDs are not really that much better in that class anyway). Dismissing SSDs as “gaming” parts as if it’s diminishing the quality misunderstands what’s happening here. It would be one thing if WD was ignoring fsyncs to achieve this performance but gamers don’t care about writes so much anyway and there’s no indication WD did that.
Source: I have the WD and Samsung parts as well as cheapo random SSDs.
The point I was trying to make by pointing out that the SN850x isn't a "gaming part" is that the SN850x is literally the top-of-the-line, most expensive consumer SSD sold by WD, and has practically the same specs as other top-of-the-line, most expensive competing parts like the Samsung 990 Pro. Being one of the most expensive SSDs on the market means that saying that the SN850x is a bad comparison because it's supposedly "lower price" is just false on its face.
To be more clear, getting equal performance without sacrificing anything would raise costs even further.
It’s easy to say moderate premium over normal business grade SSD’s but that doesn’t mean any specific number is correct. I’d say the equivalent to a 130$ to 220$ SSD assuming a stand alone equivalent exited, but the actual number depending on info Apple isn’t sharing. And yes the range is both above and below the specific part suggested.
