Mac Studio M1 Max / 32 GB RAM / 2TB SSD / April 2022

Used daily for moderate "office" usage (Slack/Teams/Firefox/RDP) during office hours. Heavier usage (XCode/AndroidStudio/Lightroom/FCP) on weekends/evenings.

I had to turn off Powernap to convince the thing to sleep. But whatever non sense it was doing (apparently stuck in Photos and Push Notifications), it has thankfully not burned the SSD!

Addendum. I just wrote 1.7GB in the last 30mins while reading HN on Firefox, and a few other web pages. Based on that, I would say the 2GB–4GB write a day from OP are fine.

To be fair an HN page can consume hundreds or even thousands of bytes

Thanks for sharing this. I need to see if linux does this.

Wow. My primary SSD on linux (with 32gb ram) has 2598 hours uptime logged and only 2.4 TB written so far.

This is exactly the kind of comparison that prompted me to post this topic. I suppose macOS just uses the SSD far more.
