Incorrect, and IOPS is also a misleading measurement that can overstate performance depending on the platform.
Anecdote Time: I had nutanix sales people try and push that the Nutanix platforms 4million or so IOPS meant that no matter what, it was the correct choice for my databases. So I had them provision a top of the line cluster for me to test... Despite having millions of IOPS performance was less than our current spinning rust based server.
The reason is a bit more complicated than average user probably knows or cares, but it evidences that raw benchmark numbers do not always accurate predict performance outcomes
As well, you're partially write about the 4k read/writes. But most day to day computer users are not doing bulk of 4k read/writes, but typically somewhere between larger and smaller hybrid. For example, reading an OS from disk to memory is going to do more consecutive, and sequential reading. Same with the bulk of larger programs loaded off disk. if you swap a lot, you'll get a lot more 4k read/writes. If you do a lot of database work, you'll get that read/writes of 4k.
it always comes down to use cases. but IMHO, if you're paying for top of the line, you best be getting top of the line. Something Apple doesn't seem to be trying to deliver.
SO while you think this was clickbaity (it was), your comments are also fairly innacurate and generalizing of the impact of the slower storage.
but you do bring up one valid point. Sequential read/write isn't the whole story and would love to see if someone could run and post a crystal disk mark run or two of this computer to see what all the reported metrics are.
