The new M2 Pro-powered MacBook Pros seem to suffer from significantly reduced SSD performance compared to corresponding equivalent M1 Pro models. Independent reviews show between 15% to 40% reduced SSD scores with the M2 Pro-based MacBook Pro 14. This is being attributed to the use of fewer, higher-density NAND chips in the M2 generation unlike what we've seen before in M1.https://www.notebookcheck.net/MacBook-Pro-14-512-GB-with-M2-Pro-apparently-has-a-40-slower-SSD-than-its-M1-Pro-predecessor.685368.0.html
A good thing $Apple$ lowered their prices to compensate.... oh wait, no of course they didn't :-)
Well luckly you can throw in an industry standard m.2 SSD card in there instead... Oh wait, Apple.
