Based on that, I would say the 2GB–4GB write a day from OP are fine.ĭata Units Written: 123,234,692 I just wrote 1.7GB in the last 30mins while reading HN on Firefox, and a few other web pages. But whatever non sense it was doing (apparently stuck in Photos and Push Notifications), it has thankfully not burned the SSD!Īddendum. I had to turn off Powernap to convince the thing to sleep.

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

Mac Studio M1 Max / 32 GB RAM / 2TB SSD / April 2022 My understanding is that you want 'Available Spare' to be as high as possible, and 'Available Spare Threshold' is how low 'Available Spare' can go before it is considering to be a failure, so the lower 'Available Spare Threshold' the better. I see everyone posting data for M1 Macs has an 'Available Spare Threshold' of 99% whereas I've got 10%. I've got 64 GB of RAM so don't have much swap usage which probably helps. It seems like most people here can do in a few months what it took me 5 years to do. I'm on a 2017 iMac that I use for both personal stuff and work. Wow.looks like I don't do much disk I/O compared to most people here. SMART overall-health self-assessment test result: PASSED On my newish M1 MBA, with the latest updates, with barely any use, 98%+ sleep, I'm seeing about 3 to 5 GB reads per day and 2 to 4 GB writes per day. Still, compared to my linux machines, this seems extraordinarily high.

I'm aware that SSD lifespans are long and TBW spec is pretty generous. This was a discussion when M1 macbooks were launched, and Apple supposedly addressed it in an OS update (macOS 11.4).īut I'm seeing really high read/write numbers.
