2TB 16GB model. 3% used.

That means that for a 256GB model, proportionally, you'd expect ~30% usage.

If this is accurate, some of these machines aren't going to last half a year to 100%.

And that's a 16GB model. 8GB should be worse.

Holy shit. https://t.co/9HcmaYgJPT

This was one of my concerns about the pitifully small (non-ECC) RAM on these machines. ¯\_(ツ)_/¯ https://t.co/yJ8VZrjaiD

any mac experts know why my SSD just fills up throughout the day, frequently going from 65%ish percent free to 100% over the course of 8 hours? reboot dumps whatever cache is loading up, but it’s super annoying.

If @Apple M1 Macs appear to be chewing through their soldered-in SSDs, this will obviously reduce their lifespan, their usefulness, and their resale value, dramatically. Apple's war on our Right To Repair will wind-up hurting itself as well as consumers. https://t.co/71l8mnuk4o

Update on M1 SSD wear issue: Available data suggests that write endurance ratings are not proportional to drive size.

256GB model: ~2000TB [1700-2300]
2TB model: ~5000TB [4300-6000]

This means that @david_rysk's currently known worst case would push a 256GB model to 100% in ~2y

People with an M1 mac, please run `brew install smartmontools && sudo smartctl --all /dev/disk0` and report back (and what kind of usage you make of the machine, especially RAM).

I'm at <600GBW on my MBP, but I don't use it heavily. https://t.co/LbhE9p7FiK

Intel Macs qualify too, if you can scale that by the time you've owned it and it looks crazy. Obviously 100TB over 4 years is reasonable.

M1 Mac SSD update…

Apple, this is NOT okay. Especially as the internal SSD isn’t replaceable. The machine is just a bit over 2 months old. pic.twitter.com/xqlSMjxwTa

This is still way too fast, but not as bad as we previously thought (<1y).

If you have >100TB written on an M1 mac, or a percentage used indicator of 3% or more, please do reply with your stats.

AppleのM1搭載ノートには妙にSSD書き込みが多いという報告が上がっており、スワップかな？言われてたんですが、スワップが減るはずの16GBでも同じ現象が起きてるらしい。
記事の例だと書き込み済みの保証可能なバイトの合計が3％も行ってるらしい。

The latest Apple M1 Macs appear to be thrashing the swapfile which is bad news for the life of the SSDs. https://t.co/FnZTL2k2y8

M1 맥 사용자들, 과다한 SSD 마모 보고해
- 지난주 일부 M1 맥 사용자들은 SSD에서 현저한 양의 데이터를 기록(쓰기)하고 있는 것을 보고해
- 트위터와 맥루머스 포럼을 통해 사용자들은 M1 맥이 짧은 시간 동안 아주 높은 드라이브 기록(쓰기)을 경험하고 있다고 보고해https://t.co/sCwBEVaGto

애플실리콘 기반 맥 제품들이 비정상적으로 높은 SSD 사용량을 나타내고 있다는 기사 https://t.co/i7qurUMOFC
심하면 벌써 내장 SSD의 TBW의 10~13%까지 소진한 경우도 있다고

Should we be concerned that Apple is already selling refurbished M1 Macs? Especially in light of this. (Note: we have no idea how widespread this is yet) https://t.co/OiwrGk67Oe
