2700Mb/s is something to complain about? Talk about first-world problems.
2700Mb/s for any SSD out of context? No, that's great speeds.
In the context of a premium laptop retailing for $1999+, marketed as "Supercharged" in ads that feature graphs telling us stuff like "The M2 chip is 1.4x faster than the M1, with an 18 percent faster CPU, a 35 percent more powerful GPU, and a 40 percent faster Neural Engine" over the previous generation of the exact same product? That is certainly is something to complain about.
Even worse,
there's no fine print indicating which storage options are slower than the previous generation.
The fact that Apple primarily refers to >512GB configurations in its marketing material is not an indication of what to expect from 256GB and 512GB models.
Omissions of key specs is and remains an omission no matter how boldly you explain the exact performance of some configurations. What Apple does with its graphs would only be sufficient if there was no significant difference in r/w speeds between the different storage configurations. But that's not the case.
As consumers, we'll literally have to wait for tech influencers to do teardowns, and have them let the cat out of the bag before we make a purchase.
Give consumers the knowledge to decide upfront how fast they need the internal SSD in their $1999+ brand new "next generation" Macs need to be instead of this cost-cutting guessing game with every new Apple Silicon release.
