Specs on M1 Pro Max SSDs?

[donawalt]

Are there any specs/model info on the SSD(s) being used in the M1 Pro Max's? I couldn't find anything on the Internet...

Like what specs? The speed is all over the internet anyway.

I have seen speeds measured in the field, I was looking for quoted spec speeds (read/write sequential/random, IOPS). I guess the rest of my list would be what form factor/interface are the drives - are they M.2 PCIe, NVMe, and what memory cell type for the flash memory. I don't have any bias or concern, I just wanted to read about what they are using - it is supposedly so much faster than other SSDs I am basically wondering why.

Much faster than PCIe3, but about the same speeds as PCIe4 drives. Majority of users don't have PCIe4 laptops or desktop motherboards yet. Xbox Series X and PS5 also use PCIe4.

Gen 4 NVMe it seems like. Can be confirmed that it's NVMe by checking System Profiler app or something like that and checking the SMART data.
