Yes, but the writes some of us are seeing are significantly greater than that. 85 TB in 12 days is 7+X the rate you’re showing. Not saying it’s accurate, I don’t know, but DriveDX shows I have used 6% of the SSD life in <2 weeks of use. (And my uses are mainly in Office / Safari / Video Conferences).
This looks alarming. I hope Apple issues a a fix soon. I have a M1 MacBook Pro with only 8GB of ram.

As my HTPC, I'm actually excited for this. Let Apple get itself into a position where they have to provide me a new unit in a year or two. Seems like a great deal.

Is it a legit piece of software?
I'm very mindful on what I install, these days.

Of course, when I was talking about the terminal, I only meant complicated things.
If there's a fairly easy command to test this thing with the terminal (without losing files) you are welcome to let me know ^^

Thank you, by the way.
smartmontools download

Edit: Unfortunately, the standard download is x86 only. You will have to build or use brew to get an Apple Silicon version.

It's mind boggling that this thread has gotten so much traction. No one is actually taking the time to calculate this disk usage in years and skipping over all the comments that have done the math. Using 1% health every 2 months would equate to over 16 years. Twice that usage would still be 8 years.

Also, the M1 is literally the same tech in the iPhones and iPad Pros and I have seen no reports of people complaining about iPads having massive disk failure. Those devices don't even have as much RAM. They also don't typically share all the same utility data that people monitor on PC's hence people never worry about it. This whole thread seems to be based more on speculation than fact.

Not sure this concern merited a front-page Macrumor article just to propel mass hysteria. Also, as much as people are revering disk platter drives in these comments, they forget how easily they broke/died for tons of other reasons other than read/write cycles.
 
This is FUD.

If the numbers being reported here are true (6% wear in 2 weeks some people are suggesting), then there would be a video in the next 3 days that will be able to stress test the SSD and successfully break it, especially when people are saying that it is not that hard to do 100 TB worth of write + read.

This will not be a theory in 3-5 days as it will either be debunked or be proven.

Except I don't think anyone knows why the writes are so high so it might be difficult to manufacture a failure.
 
That discussion is a nothing. It is based on old SSD spec knowledge. They are using tools based on old SSD specs. Nobody knows how durable the new Apple SSDs are.

Also the way people use computers changed so much. People streaming videos and music and getting notifications and downloading/uploading much bigger files than ever.

This is not 2011 anymore. It’s 2021. Of course you writing much more data. Many people don’t keep track how much data they are writing or streaming.

Also, who of those people have not enough system memory compared to how much their apps want to use. We saw so many people stupidly saying 8GB enough man UMA changes the game man UMA uses less memory man. 😂😂😂

Internet people 👏👏😝
Oof, it sounds like you’ve drank a bit too much kool-aid.
 
I (MBP M1 16GB RAM, BigSur) compared TBW result with my friend (MBP 2018 32GB RAM, BigSur).
for this "test" I made sure that Im not getting my SWAP used - and while I got ~20GB data written in one day just from other tasks I do, he got just 200MB written in 3 days!

so, based on this I would assume that the RAM is not solely a problem, but it adds its five cents to it.

what was odd for me, is that my TBW "jump" sort of matched what was visible in Activity Monitor data written summary (few gigs from kernel_task, few from launchd and few from my PHPStorm IDE), but in my friends Intel MBP case, his TBW reported by smartctl wasnt equal to what Activity Monitor reported (he had ~80GB in activity monitor, while only 200MB difference in TBW in smartctl between two days).

not sure to what conclusion this leads, but for me it looks like its not RAM that is the main cause, but its something else that either write too much to disk or maybe reports wrong numbers? (but whether its on M1 BigSur or Intel BigSur?)
 
uh.. what?

"Software ensures that load is spread evenly across the drive's memory cells"

My understanding is its the controller of the flash storage to deal with this, *in addition*to usual garbage collection not any other external factor.. Apple does that separately in software?

example: an OS has no idea what cell the flash will write to, its all handled by the logic's of the SSD. Very similar to how LBA translation works on spinning hard drives.

This thread is no more than an invitation to hate for the “I’ll never buy a first gen Apple product, I love my Intel, I can’t wait for the smallest unproven M1 issue Twitter post so I can brag about my hate for M1 computers” crowd.

End of story. Nothing to see here. I’d bet my net worth 5 years from now, there will be no more M1 SSD failures than Intel SSD failures. In the meantime, I’ll enjoy my speed demon of an M1.

Mac Mini M1 - 16GB - 256GB - 2 Months

Does this look normal?
 
16GB ram MBA, barely used.
~20TB written and power on hours are 221 ----> 100gb/hour whenever the computer is on? -->1.6gb/min --> 27mb/s constantly?

however i don't see much disk activity on istat menus. at least one of them is wrong.

That's the EXACTLY reason why we need removable SSD and replaceable parts! Apple has shown its tiresomely and irritatingly repetitive committment to the environment, but this really does opposite, forcing us to buy new Macs when SSD or soldered-on parts fail.

I spent €200 on the new GPU card to replace the idiotic AMD Radeon 5750 GPU in my 10-year-old iMac 27" (Mid-2010) so I can install the Big Sur and run apps that use Metal engine. I see no need to buy new iMac when my current iMac runs beautifully to this day.

The problem with your close minded statement is the fact that SSD’s aren’t failing. You are complaining about a problem that doesn’t yet exist. Do you complain that your hamburger is burned before you start cooking it as well?
 
I was literally going to buy a MBA M1 this weekend.

So guys in light of all this......I should just postpone my purchase? But then again, surely Apple will patch this in a future software update, no?
 
I forgot I had purchased this a good while back off their website. The reason I didn't see what others were, is because the App Store doesn't offer the full version from their website. I wasted $6 before I found my old license. At least the mystery has been solved.

Thanks for helping out with the response. I see it now.
I'm not seeing what others see either on my 2014 13" Retina MBP running iStat Menus version 6.51. Rather than seeing the lifetime left under Status I see "S.M.A.R.T Status Passed" ......
