But even at half speed it would be able to write at 100-125MB/s of GigE, right?Yes WD My Cloud EX2 can and it works well - I just think the main issue are all the complaints about M2 performance and I'm happy with the basic M2 Mac mini with 512GB, but I would have been pissed off if I had bought the 256GB version with half SSD speed just to save USD 200, I realize I don't get a 16GB Pro, but Apple could have been up front what you get, or not get..
I find it odd that the main use case for faster SSD (it appears, based on comments here) is swapping. But you guarantee that you will swap more (relative to having 16GB of RAM) by having "only" 8GB of RAM, thus you will see the issue more.
And because even the fastest SSD is hundreds to thousands of times slower than RAM, whether the SSD is 1500MB/s or 3000MB/s, you'll still see the slowdown far worse than if you had the RAM required during the VM swap event.
But you didn't buy that RAM.....?
