2021 16" MacBook Pro, Apple M1 Pro silicon, 16gb / 1TB, purchased March 2021. Personal laptop, super light web dev (hobby projects): === START OF SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED SMART/Health Information (NVMe Log 0x02) Critical Warning: 0x00 Temperature: 27 Celsius Available Spare: 100% Available Spare Threshold: 99% Percentage Used: 6% Data Units Read: 509,334,138 [260…

An update if people are still watching the thread. Got the following output today (~2 days later):

So looks like my MacBook did an average of 87GB /day over the last 2 days (approx).

Which seems a lot better than the 18 month average, which was 700GB /day.

Hopefully means it's since been fixed, and I haven't destroyed my SSD too much!

How does your workload look?

I'm a researcher, so I do move/access a lot of data locally (10s of Gbs, not Tbs usually). Lots of Jupyter/IPython interactive workflows. Starting to run some more web development stuff/Docker containers.

Earlier quoted context omitted.

Replace the SSD asap. It's not worth saving $80 to deal with the random IO lag well worn SSDs have.

Forgot to specify that I have the 15" model. So I would have to replace the entire main board since the SSD is soldered onto it...

Wow, the touchbar MacBooks from 2016 onward are literally disposable. Glad not to participate in that ecosystem!

Yeesh, did not realize Apple was this into making ewaste, but that is definitely their fetish.
