Hey!

How about to use safari now? Is it ok now? Or should i continue to use firefox / brave.
Well even though Safari is just as heavy on caching as it’s always been, now that it’s fairly certain that these drives are rated in the range of 1000-1400TBW even for the lowest 256GB, it’s fair to say that you can use Safari and not have your macbook die due to excess writes within its expected lifetime.

But if you still want to stay on the safe side, then firefox / brave with memory saving extensions is the way to go. Personally I use a mix of Safari, Brave and Firefox and I no longer get worried about SSD writes due to the SSD’s having such a high TBW rating. I consistently stay under 5GB written per hour anyway which should yield me an SSD life of 30+ years.

Firefox has a setting which reduces CPU and RAM cost.

There's one practice that I use now which cuts down on RAM use:

I like to go into a YouTube catalog and then open the videos that I'm curious about. This actually uses a lot of CPU and RAM. It's actually far more efficient to open one video, and, if I'm interested, save the title and link to watch later, close the tab and then look at the next one.

I bought a new MacBook air about one month ago, this time with 16GB of ram, I installed straight macOS 11.4, I'm keeping an history of the disk stats, here it is after about 1 month of light usage (PS: I'm using in almost only to browse the web with Safari, with tons of tabs 40/50 always opened, Mail and Reeder).

At the top the login time, I will keep to monitor it over the time but for me this bug is no more here:

Hector Martin has found a guy on Twitter with the first dead SSD in an M1 machine. It started having issues at around 600TBW. That is about in line with my own SSD lifetime experience. You are likely to start seeing issues at around 500 to 800TBW. Don't expect to reach a Petabyte. At least not on the smaller drives below 1TB capacity.
Link?

I'll be disappointed if this happens to me. Though this is somewhat of a throwaway system for me which I expect to replace with a 32 GB or 64 GB system within a year.

Professional Enterprise IT Storage Admin (8 years) / amateur photographer (20 + years) here. Very familiar with Windows ,Mac OS and iOS. Built many computers / multiple Plex servers. Have multiple backups on Time Machine (2) + (1) original drive from last MacBook Pro 15 which had the GPU white screen issue that many 2012 models had.

Bought a 2020 M1 Macbook Air 2TB , 16GB. I have about 1TB worth of Nikon NEF files. Did migration assistant using a Time Machine (2.5 inch portable Seagate) backup from a dead GPU 2012 Macbook Pro 15. Migration assistant worked well (I assume it moved files from Mac OS Extended to APFS). After couple months, started to noticed corrupted image files , yes, my beloved NEF (RAW) files from previous shoots / trips. Things like vertical or horizontal neon color lines from top to bottom or bottom to top. Never had any issues with my previous Macs doing this (or any PC for that matter). Went to my primary Time Machine drive (#1) and found that the files also had same corruption , due to Time Machine backing them up with the errors.

Went to my 2nd Time Machine backup (#2) (3.5inch external), also taken just before the 2012 died (but not used for migration assistant) and the files were all FINE. Then, pulled the 2TB drive from the 2012 and put it in an enclosure and confirmed those files are FINE too.

Deleted the corrupted files from finder + LR catalog on the M1. Then re-imported same images to the M1 and LR, now they are "fixed". However after fixing the first few, I started to notice other files (also NEF images) started to have the same issue. Now the count is up to 50-60 images in a catalog of 30,000 (0.16% corruption , approx).

Took it in to Apple two weeks ago. Showed them the file corruption / bit-rot and showed them the good files on the original 2TB which was removed from the old 2012 MBP.

They wanted to know how to isolate it to just this machine being the cause of the issue. I said "I can isolate it to this machine because these files are only starting to get corrupted now that they're being stored by this M1 Air 2TB SSD. Some of these NEF files started on a 2008 MBP 15, then moved to a 2012 MBP15 , and now to this 2020 M1 and I have NEVER had any image corruption or file loss.

They wanted me to restore + redo the migration. Pushed back and got the senior genius to come take a look. He said if I wanted to leave it for a few days they could send it in for more diagnostics (r/w tests) and then for possible repair. I said sure no problem.

Fast forward a couple days, the store calls and says they have the M1 back from repair. I asked what the repair was and they said we went ahead and replaced the display assembly / LCD. Now, you can imagine my disappointment and frustration. Because the first apple genius put in the notes "customer has vertical lines on images" I guess is interpreted by the repair facility as a bad screen.

I am deeply disappointed with the level of service from Apple and almost insulted by their "fix" or replacing the screen. Did they not note that while I had the original drive plugged in and pulled up the exact same file, that it displayed properly??

I will go pick it up tomorrow. They also said that they wiped it to factory. So, I guess I will have to play their little game, restore my time machine backup to this M1 again, and start using PS and LR and monitoring for more file corruption.

TLDR - Seeing random corrupted image files now that my catalog of NEF files are stored on a 2020 M1 Macbook Air

I normally keep my image library on multiple computers and they're in Time Machine (two disks as one just died). I have 5 TB SSD on my Windows desktop and am considering an 8 TB HDD for archives or just throwing random junk at. Data corruption is always concerning. I wonder if Time Machine has a file verification option. I'd seriously hate to lose old images.

It could be a bunch of things. Time Machine has been bulletproof for me since I started using it back in 2008. I've restored systems and individual files many times and have had no loss, or corruption. I do not have any M1 systems though I have a 16/500 Mini arriving on Thursday. I do not plan to store anything on it that won't be on other systems. It's more of a client with storage to my big Windows system.

I worked in Corporate Support back in the 1980s and we'd work pretty hard to come up with a reproducer for this kind of description. We would drop everything for crashes, incorrect results and data corruption as those are unacceptable in enterprise database processing.

I was very glad I had 2 Time Machine backups + 1 original drive. You can never have too many backups. I know my post is long, but hoping that this issue gets some visibility. I expressed my concerns to the "genius" saying that "I don't know if I trust the M1 to hold these files after seeing this type of corruption".

So, on one hand, we have an IT pro (not bragging, but I am a storage admin for work) vs a 6 month old 1st gen Apple product with people all over the web talking about excessive wear on the new SSDs.

I am going to say the issue is 99.9% on the M1. Now, if that means the migration from MacOS Extended to APFS caused the issue , or if the issue has to due with higher than expected SSD usage over 6 months, I do not know.

I did read one post on fstoppers where a photographer was importing from an SD card some movies they recorded. He reported that those files were corrupt and unplayable. That was also on an M1 Air.

I'd guess that filesize has something to do with it as we would be seeing far more reports if this were more common. A fairly simple test would be to backup large images from a benchmark and then restore them to an M1 and then do a file comparison between the restored files and the benchmarks. Another would be to save the name of a couple of files that had corruption and then backup and restore those specific files.

Well, these are kind of small files , 24MB - 28MB. I don't shoot video, so I don't have GBs or TBs of data being shuffled around. My guess is maybe it's an issue with the 2TB SSD , otherwise ,yes, more people would be reporting the same issue.

I found and provided it along with a critique back in #2,093 which was actually a repost - expansion of #1,496. Here it is:

I think this is a variation of what Ryan Hileman quoted on twitter:
"I have someone with a failing M1 disk. 4mo old, 2% spare, 10% thresh, 98% used, 600TB write 500TB read, 200h "on", 10,000 "Media and Data Integrity Errors". Machine had an inconsistent glitch in my app. 16/512GB machine, typical RAM use 9GB. Working on RCA, ama."

Well it was claimed this genius was using this as the postgres server for a bank. This is like using a crowbar in place of hammer; yes you can use it that way but it is really really dumb.

Something I didn't notice and now do is that 2% spare; that starts out at 100%. So they have blown through 98% of the base capacity and 98% of the spare. Based on other results there is something way wrong with those numbers.

Let's be clear here these Macs were never designed for that.

The reply right after this #1,497 summed it up perfectly: "Clearly that case is completely invalid then, and can be disregarded, as that is not something the system was designed to do at all."

Some additional research produced SSDs for SQL Server? Good or Bad Idea? which stated that SQL has insanely write happy with one person saying "unless you have a ton of money to spend - it's a bad idea. SQL does a lot of writing, which SSD is slow at. if you do it, ONLY go Enterprise class SSD (which will double to triple the price,) but extend the life of the drives by 5-6 times because they have smarter controllers and embed roughly double the amount of drive space as printed on the label to account for sector death."

I seriously doubt the first M1 Mac have Enterprise class SSDs. So our only example of a M1 SSD failure is flawed to the point of uselessness and involves apparent misuse of the M1 Macs available.

So there is the link and why it is totally useless.

If someone is really worried about it, they could run their whole system on an external SSD or an SSD farm. That's what I would do. I'm not going to worry about it as I expect to get something with lots more RAM within a year.

I addressed this in a post in another thread (we have too many threads on this subject):

Read Found Potential Culprit to High SSD Writes / High Swap Usage in M1 Macs, At Least For Me... The key part of that: "Then I realized that some of the long-running apps running on Rosetta 2 were hogging quite a bit of memory, ... I also knew that they are built on Electron/Chromium which can be memory hogs."

"So I tried uninstalling these apps, instead opting for web-based clients running in Safari since a couple of days ago and guess what...only 40GB SSD writes per day. So it could be Rosetta 2 that causes high swap usage that leads to high SSD writes, or it could be the Electron/Chromium-based apps that seem to just be memory hogs. Either way, I'm happy to see that my SSD write figure is now in the much more acceptable range."

M1 Mac SSD Swap Issues Explained: Should you be WORRIED? says much the same thing.

M1 Mac owners are experiencing high SSD writes over short periods of time gives some more data across several platforms

I followed that up with this:

So as I said the SSD get kicked in the head by the amount of RAM the program needs, it liking to write to the HD like a drunken sailor, or worst both.

Oh on the claim this is only happening with Big Sur, somebody ran these tools on a 4-year old MBP, Percentage Used: 100%, Available Spare Threshold: 10%; 448 TBW. Sadly he didn't state the size of the drive but as you can see this is not unique to Big Sur. Heck, Big Sur didn't even exist in 2016-2017 and those numbers are coming from a Mac that shipped with either Sierra or High Sierra.

Similarlly, I have seen corrupted files on my old 2013 Intel Mac because there was some piece of software causing Time Machine to flake out and write corrupted data to the back up drive.

Tl;DR: There are too many degrees of freedom and variance in results to claim "the issue is 99.9% on the M1". Could be some third party program that interfered with Time Machine, one of the early versions of Big Sur (which had issues), or a bad SSD (they do happen) in the M1.

There are a few cases reported here that should worry people. The recent one was 13% used at about 420 TB in a couple of months. That needs investigation to figure out how to reduce the write rate. But mostly it is the potential for problems that scares people. And people seem to have a hard time with the arithmetic. Seeing a few Terabytes written in a month seems bad until you do the math.

I generally watch the amount of RAM that I'm using on Macs because my systems are old and performance can drop having to SWAP. My goal is 0% SWAP. Ever. This is really easy on my 128 GB Desktop but the rest of my Macs are 16 GB systems so the idea is to run one or two Macs and split up the programs between multiple systems. Or run macOS on Virtual Machines on my big desktop.

My M1 Mini arrives in a week and the plan is to hook it up to two displays and then monitor RAM usage. If I see any swap, then I'll add another 16 GB Mac onto my desktop and split the programs between the two Macs and that should eliminate any SWAP. I can use an external SSD as well. I did that to try out Monterey for a week and it worked well for that. I have a bunch of SSDs on my table that I play around with. The real solution is for Apple to provide more RAM and for software vendors to port to M1.

Some of these NEF files started on a 2008 MBP 15, then moved to a 2012 MBP15 , and now to this 2020 M1 and I have NEVER had any image corruption or file loss.

They wanted me to restore + redo the migration. Pushed back and got the senior genius to come take a look. He said if I wanted to leave it for a few days they could send it in for more diagnostics (r/w tests) and then for possible repair. I said sure no problem.

Fast forward a couple days, the store calls and says they have the M1 back from repair. I asked what the repair was and they said we went ahead and replaced the display assembly / LCD. Now, you can imagine my disappointment and frustration. Because the first apple genius put in the notes "customer has vertical lines on images" I guess is interpreted by the repair facility as a bad screen.

I am deeply disappointed with the level of service from Apple and almost insulted by their "fix" or replacing the screen. Did they not note that while I had the original drive plugged in and pulled up the exact same file, that it displayed properly??

I will go pick it up tomorrow. They also said that they wiped it to factory. So, I guess I will have to play their little game, restore my time machine backup to this M1 again, and start using PS and LR and monitoring for more file corruption.

TLDR - Seeing random corrupted image files now that my catalog of NEF files are stored on a 2020 M1 Macbook Air

Have you considered trying external storage as working storage to narrow down if it's internal storage or file system?

I find that sometimes I do, sometimes I don't. It seems that it is usually later in the day that they appear as they seem to discard any results for the previous day.
Make sense actually :)
It is new laptop, I got my :apple:MBA 16/256 today and using it only for last ~9 hours.
Code:
com.apple.message.smart_data_units_read: 640268
com.apple.message.smart_data_units_written: 414292
It is ~212GB written, but with installed 11.4 update right after first start + full MS Office + Adobe CC with Photoshop + all needed software.
Now I'm done with initial setup/updates and using it normally, I will check those number tomorrow after regular day of usage.

According to Drivedx, my M1 is still in the GB range.. Does this mean I can now trust Drivedx is reporting the same numbers as smartmontools would?
In DriveDx you can choose whether to report in GB or in GiB units.
1 GB = 1024^3
1 GiB = 1000^3

So if I leave it at default like this I get GB not GiB, correct ?

Format SMART data sizes in units based on powers of 2 (1k= 1024) gets you GiB
Format SMART data sizes in units based on powers of 2 (1k= 1024) gets you GB

So without a √ it counts in GiB.
With a √ it counts in GB.


Easy to check. Try both.
The smaller number you get is in GB. (Division is by 1024^3)
The larger number you get is in GiB. (Division is by 1000^3)

Okay?
