M1 Mac owners are experiencing high SSD writes over short periods of time


Some extra legit users of the unique M1 Macbooks are experiencing extraordinarily high force writes over fairly short time.

Basically the most excessive cases contain “consumed” about 10-13% of the utmost warrantable TBW mark of the SSDs (given their capability & utilizing values for an analogous market-readily accessible NVMe drives). 

Here’s possible macOS-linked behaviour and Apple can repair it. 

I sold an M1 Macbook Air proper per week ago and already contain about 300GB of writes on the SSD after some light multitasking. I am currently fascinated with returning it.

My put up in r/Mac: 

Update 13: 24

Update 2:

oh i’m reckoning on it. 

Cell phone: iPhone SE 2020 | 64GB iOS
Predominant Laptop: MacBook Knowledgeable 15″ Late 2011 | Core i7 2675QM | 16GB RAM | 250GB SSD | macOS

Secondary Laptop: MacBook Knowledgeable 13″ Mid 2012 | Core i5 3210M | 8GB RAM | 250GB SSD | macOS

PC: Supermicro X8DT3 | 2x Xeon X5650 | R9 290X | 32GB RAM500GB SSD | Bitfenix Disclose 850W | Manjaro

Effectively, is now not it supreme?

Solder the ssd so as that it might perchance per chance in point of fact perchance well now not get replaced and machine just isn’t realistic as soon as its unnecessary, limit guarantee protection in accordance with TBW, abolish OS write entire bunch of stuff so as that TBW limit is exhausted quick and the ssd is now not any longer lined by guarantee. Sounds fancy fraud, would now not it?

In actual fact even though – soldered storage is and repeatedly changed into as soon as ugly knowing, and that’s the explanation the motive i am individually staying away from many apple stuff in the intervening time, whereas i extinct to fancy it a whereas ago…

Man, that sucks. Especially in case you’ve got sold a smaller force size and utilizing an external one for instance. Can you now not proper alter the web thunder file size fancy on Windows?

That’s an F in the profile pic

My M1 Mini that I in actuality contain had since round 20 November 2020 (ordered it proper after apple tournament).

Given I in actuality contain 16 GB RAM so my pc would now not web thunder significant.  

1,5 TB Written, screenshot taken proper now.

However these what these instruments document are questionable, the most realistic possible one is: Since I am working from residence I am engaged on the computer nearly on on each day foundation foundation and these instruments exclusively document 95 hours vitality on, SINCE THE END OF NOVEMBER!

And even though I’d contain a larger data write count to me here’s a nothing burger.

Effectively to be correct I assemble now not know what the fuss is, math below for why. A usual and conservative DWPD mark for person SSD would be 0.2 and the Apple M1 gadgets had been round for what roughly 90 days?

(0.2 512GB) 90= 9216GB

(0.2 256GB) 90=4608GB

So anybody with lower than 4TB of data written is exclusively elegant, your SSD is now not wearing out abnormally, even though we use 0.1 DWPD anybody below 2TB is sublime. And these DWPD/TBW guarantee figures are in actuality successfully below what the SSD NAND is apt of.

I assemble now not know what they are reading but I highly doubt anybody has extinct 13% of their anticipated SSD life.

Also FYI most SSDs in the person market are nearer to 0.4 DWPD so…..

150TB in 432 hours is 5.79GB per minute.

15.7TB in 191 hours is 1.37GB a minute.

58TB in 256 hours is 3.78GB a Minute.

Lets attain some maths…

150TB written in 432 Hours.

150 / 60 offers us writes per minute in TB.

150 / 60=2.5TBpM

Case 2

15.6TB in 191 Hours.

15.6 / 60=0.26TBpM or 260GBpM.

Case 3

58TB in 256 Hours.

58 / 60=960GBpM.

How the holy hell can the system be writing over 2TB per minute? In actual fact I am thinking here’s a sensor bid, if the system changed into as soon as repeatedly writing 2TB per minute to the SSD there would be no bandwidth left for the rest, proper opening an app would contain minutes (if now not hours).

I’d thunder : (150 / 432) / 60=0.0058 TBpM

Must you write 150 / 60, it manner 150 TB writes in a single hour 😄

Effectively, i creep to procure this as example.

It’ll be 150/432 ~ 0.35TB/h, or ~358GB/h

Then 358/60 ~ 6GB/m

To be correct, for one of your other parts now long past, SMART data is understood to be unreliable and even extra so with SSD. A form of SSD firmware don’t count data written in an in actuality identical old logical manner so in case you be taught it with a generic SMART reader it be going to be injurious. I exclusively be taught force wear utilizing the vendor offered instruments, now not lower than that is rather honest.

Which if i’m working out the OP is the total criticism.

WD Dark 2TB has 1200TBW. The man with 2TB MBP has 150TBW written to this point over 2mo. That’s 12.5% of the TBW figure. His force additionally extinct up 3% of spare blocks. If he carries on, the force will reach 1200TBW in 16 months. After that it be unreliable and the force might perchance per chance perchance well fail anytime (or retain working for one other 100s of TBW)
