I checked the first two and it’s 7,000 read / 5,000 write. Pretty sure Apple said read AND write, which would be a lot faster than those. I might go back and rewatch the keynote, but I still thinking we are arguing pointlessly as Apple has always overcharged for SSD and RAM upgrades vs the price you’d pay elsewhere. Thanks for the DV though even when what I stated was right! ;)

It achieves this speed by not insisting on flushing to disk when requested: https://nitter.net/marcan42/status/1494213855387734019
When configured to ensure data integrity in the case of power loss (more important in this new M1 Studio machine unless it comes with integrated battery), then it's a lot worse.

I have a 8TB M1 Max. It pretty consistently has a max write speed of ~7.3 GB/s and max read of ~5.4 GB/s. No idea why or how write is faster, but that's not a typo.

Their website just specifies read speeds with no mention of write speeds. It's also "up to" and tested on the 8TB models. Assuming it's like other SSDs smaller capacities are usually slower.
