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. https://twitter.com/...

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://twitter.com/...

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

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. Big Sur 11.2.1, https://mail.app/ is not syncing email.

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://twitter.com/...

This is not good- but easily fixable via software. Apple needs to hurry up with that. I'll investigate on my M1 Macs and report back what I find https://twitter.com/...

We are already throwing away perfectly good computers and phones because over time software upgrades make the devices progressively slow & incompatible. Now we have computers where even the hard drive cannot be replaced and limited lifespan seems built in. #Environment https://tw…

@never_released Do we know they're not doing a memory/charge backed caching strategy in the controller and are these actually hitting the NAND?

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.

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.

This story about M1 Macs with excessive SSD read/write data does seem to be true. On the left, my 2017 iMac; on the right, my M1 Air from last fall. Somehow, in 3 months, it's registered about 15-20% of what my iMac has in 3.5 years? Not sure what the implications are, but weird.…

The latest Apple M1 Macs appear to be thrashing the swapfile which is bad news for the life of the SSDs. https://www.pcgamer.com/...
