These MacBooks DIED from SSD Failure & How To Prevent It (Not for RICH dudes!!)

[@Chalisque]

The other thing as to why you get a larger SSD than you think you need is an issue with wear levelling. The TBW metric is oversimplified. The SSD has a number of blocks (say 1000 for a simple example), each of which can be rewritten 1000 times. What happens if the SSD keeps rewriting the same block rather than sharing the load? If your SSD is 80% full, then all that writing and rewriting is spread over the 20% of blocks remaining, which means that those blocks get worn out way quicker than the TBW lifespan metric would indicate. I'm writing this on a refurb Thinkpad I got off eBay for £150, which has an nvme slot. It's current SSD is small (250GB) and is about 60% full with all my music and other software installed. But as and when that becomes an issue, it is an M.2 SSD, so I can replace it. The RAM is 4GB fixed plus one slot (currenty 4GB but I can stick a 16GB stick in at some point). I can understand fixing the memory to the CPU (better speed/latency). Having two tiers of memory (fast RAM on the CPU and secondary RAM in slots on the motherboard) would complicate things. But soldered storage is a cardinal sin. I have a friend who is mac only. Her current Mac has served her well for 10 years. A new mac will cost a lot, and this video points out what I'm very concerned about, namely that she won't get 10 years out of a new mac. 5 if she's lucky. So the cost is amortised over half the time, so is effectively twice the price per-year compared to her current mac. More and more Macs are becoming a means for Apple to rinse the rich, and to hell with everybody else.

[@PaulSebastianM]

TBW is per entire drive capacity, before failure. So divide that with the number of TB of the drive and then convert to GB. You then get how many TB a single GB of free space on your SSD can be overwritten with before that GB dies.

[@rafaelreusch]

Maybe SSD companies have clever tech that randomly rearranges the stored data to different datablocks to prevent the issue your saying... doesn't seem that absurd of an idea hahaha

Louis Rossman also covered this issue with the failed texas intruments component failure. Its absolutely shameful how apple designed the logic board with no abily to protect the ssd from being destroyed

[@mindsoulpower]

shameful? it is CRIMINAL! they do it on purpose

[@eddiegardner8232]

It would be pretty easy to clamp that converter output to ground if the voltage output exceeds a certain level, to protect the SSDs. The converter chip is probably being used too close to its rated limit, leading to eventual premature failure. The SSDs themselves should be mounted on a socketed sub-PCB to facilitate their eventual replacement and/or upgrade, if needed. To do otherwise is just greed forced into bad design practice for higher profit, from overpricing the value of these commodity SSD chips, as installed.

[@SA-mv3vf]

And guess what , this video states the ssd is replaceable but sadly it is not as the bios and firmware is also loaded from some sections of the drive hence the reason why it doesn't even post to screen with the dead ssd , older models you could at least see some picture even with a dead ssd, even louis Rossman covered it and said the ssd was non replaceable....I currently have a 16 inch 2019 with this same issue , after diagnosis, I discovered all ssd chips are shorted to ground (even after removing the Texas chipset)

[@bartonlynch]

As an Apple Certified Technician you nailed this topic very well and very informative, but… 1) You made the swapping issue more dramatic and dynamic than it usually is. Yes, swapping is bad, but it's not as constant and dynamic, meaning that the "200MB" swap file is not constantly being written back and forth, it's the amount of swap being used. And Swap memory is not and does not act like Random Access Memory, that is wrong, it's a temporary inactive "cache" part of the used memory stored for later use and to give space back for immediate needs. 2) You left out an important issue about SSD space and longevity, filling up the drive and keeping it that way as your main and only storage is bad, very bad, as there is little room for the OS (and you) to perform common tasks and for the SSD controller to execute wear leveling. Leading to a premature wear of cells. 3) The type of NAND flash (MLC, TLC, QLC) chips have a huge impact and it's not simple or short to explain here, a good excuse to investigate and make another educational video. In short, avoid QLC based SSDs. Apple uses TLC from all the manufacturers that supply the chips, fortunately. 4) TBW is not an "end of life" point, but an average MTBF (meantime between failure) measurement and the majority of drives can exceed this "lifespan" metric many times. Your example proves it as the drive had 80% life left after doubling its TBW. In theory and statically in practice (not counting manufacturing defects) the life of the SSD in soldered MacBooks will out pass the lifespan of the machine by the average user ownership period of 4-5 years for an 8GB SSD. But if the TBW is higher, better (a larger drive will always be recommended as you mentioned in the video, double that if you add more RAM, but of course this is expensive when it comes to Apple's pricing scheme). Good video!

[@Slurkz]

Amazing comment, thank you for taking the time to inform us.

[@sbramble01]

​ This dude @creamwobbly seems real confident about this. Anyone else have an opinion on swap vs cache? My Macbook is on the line!! haha

[@mootsym]

Can you help me understand when the Mac says that x amount of MB is being used in the swap? Is that.. like 200mb/second? .. like always adding 200mb? Or just 200mb... sitting there not changing.. until the figure does change? So if that number stays the same for 4 hours and I close the computer for the day.. the total MB written to the drive for the day will have been 200mb? But what if at hour 2 it drops to 100mb? Is the total then 300 for the day? 100? spitting the difference at 150?

[@puspamadak]

Swap memory is actually used as real RAM. The OS certainly tries hard to move the inactive parts of the memory to swap while keeping frequently used parts on physical RAM, but it doesn't succeed every time in prioritising those data.

[@one_step_sideways]

@@mootsym Commonly the less swap the better. Some people have a 10GB swap file on their M1 Macbooks with 8GB RAM, though not enough time has passed for those M1 Macbooks to start dying from SSD failure en masse. It's certainly not 10GB/second. But swap storage acts any way it pleases and it usually writes more randomly than not, meaning that if MacOS wants to write some data from the RAM to the swap file, it certainly would, without really discerning what data it is. Apple made a conscious decision to _specifically_ use swap storage as if it's extra RAM. No one else does that in the same scope as how Apple does it. They knew what they were doing, and what they were doing is screwing their customers over.

It will make no difference. The SSD where the OS is installed is where the swapping takes place. Saving downloaded files to the external drive will have minimal impact - it's the swapping that is responsible for 99% of writes.

[@ERTU758BJK]

Hello, first of all it is a unique content. You explained very useful things. But a TBW lifespan doesn’t mean that SSD is going to die. It means that the manufacturer will no longer give guarantee to SSD. There is a lot of working SSDs which has already completed their TBW lifespan years ago. It is more about the breakdown of the storage cells in SSD. In normal conditions, most probably a user can use the SSD for couple more years after completing the TBW lifespan. It was a great content thanks to you.

[@iBoffRCC]

Youre right! When we uploaded this video, we already clarified some facts regarding the TBW to this video description, of what the actual scenario when the TBW limit's reached. and what you're saying is completely true, as its not always die 100%, but since we've had some SSDs behave erratically when TBW limit's reached on these Macs, so we'd like to call it dead. And as a logic board technician's perspective, when we repair MacBooks with dead SSD issue, ETHICALLY we will never install bad TBW SSDs to your client's Mac.

I don't know if it's intentional or not, but you make the SSD usage ware case sound quite more scary than it actually is. My first ever SSD (a 256GB Samsung 840 PRO) is being used in a PC that almost never shuts down for almost 10 years now. It has 74000 hours of operation, and 58 TBW used, with typical user usage. I don't know if such an old model has 300TBW limit or not, but even if it has 150 TBW (as if it was a modern 128GB SSD) this would mean that it has more or less another 15 years of life in it. It will be 25 years old if it ever reaches to that point! I have had mechanical disks that failed quite sooner than the 10 years mark! The only real issue with Apple is that SSD's are soldered on the board, and it's not easy to replace/upgrade them. That's more of a concern if the SSD goes faulty, rather than if it wears out due to usage and reach it's expected TBW after (most likely) 15 or 20 years.. Especially since Apple declares most of it's products obsolete after 7-8 years of their release (and unfortunately Microsoft copied with it's Windows 11 upgrade policy). IMHO a typical user should just enjoy the ease and convenience SSD's offer, and not live in a constant fear that he may have written a few GB more today on his SSD, or that the movie he downloaded damaged his disc. And finally IMHO unless you need HUGE storage space, external discs belong in the past and should stay there. Granted, USB C protocol is very fast, but external discs are bulky and messy. If my internal disc can fit all the data I need and leave at least 25%-30% of the drive empty, why should I bother to carry around spare discs, remember to connect them, then remember to not move my MAC while the discs are connected (or to not use it on my lap) then remember to eject them, and finally disconnect them? Supposedly MACs are famous for the ease of their usage and the total user experience they offer, no ? PS: I have both a 2021 MBP and a 2021 Asus ROG laptop. The Asus came with 1TB SSD on board. Not only this SSD can be replaced/upgraded, but it also offers a second M.2 slot. So now the Asus has it's original SSD and a second 2TB Samsung 980 M.2 PRO. And the coolest thing is that I didn't had to send it away for the upgrade, nor become an expert to desoldering/soldering components.

Hmm… I used a 2012 MacBook Air with 128 GB of storage and 4 GB of RAM for 9 years, incl. Garage Band and Logic Pro projects. My SSD died once, but not really. A computer repair service soldered it, and I didn't even loose any data; and the Mac worked fine after the fix until I sold it to a friend as a beginner MacBook. As far as I know it is still working fine, haven't heard anything different. Thanks for the great explanatory video. Keep up the good work! :)

How many TBs written?

[@MoD_Master_Of_Disaster_]

Straight after having finished installing and configuring my Mac Studio Max (standard model with 32GB ram and 512GB storage) I moved my user profile to a TB3 NVMe enclosure with a 2TB Seagate Firecuda 530 in it. That leaves the precious internal storage for te OS and Applications. True that the internal storage is faster, but you won’t notice a difference in real life. So when I copy a file to my desktop it is actually on the external storage, this goes for all user profile related data like Pictures, Documents and Download folders.

I manage a fleet of 100 PCs in my company and saw many broken HDDs but not even once had a damaged SSD. Some are up to 7 years old and Soldered NVM ssd's are not too uncommon here and we don't even buy very large drives. I never buy PCs with less than 16gb Ram to prevent excessive swapping. I dont' believe any regular user will ever reach the TBW of it's disk.... At least not before the battery has died and the external aspect of the case will make me buy another computer for this user. The over-voltage problem you mention is just the result of a terrible motherboard design by Apple and I smell a class action coming at them. Computers are not supposed to fry their SSD. It reminds me of the Nvidia chips problem on Mac Book Pros a few years ago, which to be honest was better handled by Apple in terms of after-sales support than by most PC manufacturers similarly affected by that same plague (those Nvidia chips were the culprits).

[@AndriiKakoichenko]

Maybe it depends on software that your users use. Personally I understood that something wrong with my 8GB M1 when started to use Adobe Lightroom (software that uses 70% of RAM at any system and has no slider to adjust it), and noticed, that it writes 10TB per day of usage due to swap. So right now I'm not using this software on my Mac anymore, and turned off swap completely (unfortunately, I don't know is it possible to activate OOM killer, so sometimes it freezes, when open too much apps).

Nice video. My office issued M1 MacBook Pro has 64 GB RAM and 1TB SSD, so it's most likely going to outlast its useful life. My M2 MacBook Pro has 16GB RAM and 512 GB SSD. I don't run too much heavy stuff on it, so I haven't noticed it swapping. But it's shocking how much memory apps use these days. The KZbin browser tab displaying this video is currently taking 0.6GB! So, it's easy for the usage to quickly add up if you have lots of stuff open. I also have a 2014 Mac mini with a (replaceable) SSD that's going strong - used primarily as a media server, so it hardly does much writes. BTW, Random Access Memory doesn't mean what you say - "data is randomly moving in and out". Here, random simply means you can access data (read or write) in approximately the same time, regardless of which location it is stored at. Contrast this with a Hard Disk or even tape where certain locations take longer to access than others.

A lot of companies have special engineers that work on how to limit the lifespan of the device. They have two methods: hardware and software. Hardware is with the limited TBW in combination with soldering it on the mothermotherboard, and with the voltage thing zapping it. Then they got limited OS updates. Older devices can the new mac OS just fine, but they fase them out so you can not download any new programs from the macstore because it will not run on the older OS. There are workarounds for this but it is kind of tedious to get Sanoma on older devices. But once you get it done what you see is: the performance is great, zero issues. So they are throttling it on purpose to a max version of OS. It is a choice. Good thing i bought the maxed out version, i never knew the smallest ram and ssd will do 4 times as fast as the bigger ones. Great tips also, thanks.

[@tomsun3159]

I think you missed one important point for the SSDs (not only for the soldered ones in the Macbooks), if you erase a file on the SSD, you will also loose parts of your TBW, as the the cells are cleared what is also a writing process, that makes all even worse, you can try to use more provision to have more spare-cells, what can expand the lifespan of the SSD, but i don't know if this works at the fruit computers. Also very important the more states a cell has the worse the endurance SLC, TLC, QLC. My conclusion: avoid like a plague soldered SSDs, avoid like another plague proprietary formats of SSDs. ONLY standard connectors (Sata, msata, m2)

[@robertbrzheintzbrz147]

I think you got this wrong. Deleting a file does not write over the data blocks. No OS does that, you need special software to do that. Deleting a file only adds the blocks to the free blocks list and removes the entry in the folder.

[@net28573]

SSDs are a gold mine for apple strategically. It makes me shudder when I'm reminded that they're soldered on. For anyone that's ever attempted data recovery, it's always harder to recover a corrupted SSD. HDDs give you indicators that something is going wrong and you have multiple avenues to attempt recovery but an SSD is ridiculously more difficult to recover data from successfully. I was replacing the HDD on an old laptop that was pretty slow with HDD issues popping up and after cloning the drive it ran almost like new. My friend around the same time sent me their SSD to see if I could fix it because it was glitching and intermittently experiencing slowdowns. While I could access the drive, certain files would trigger intense slowdowns if I interacted with them. I had an SD card behave the same way before and knew it was corrupted. While a partially corrupted HDD can be cloned, SSDs refuse to even engage wih any cloning software or hardware. I only use an SSD in my laptop because Windows 10 doesn't run well on HDDs because they skipped optimizing their file system because they didn't think they needed to anymore with faster SSD speeds. I only bought that laptop because it had a secondary HDD that I could offload the heavy file manipulation to. While SSDs have a finite number of writes before burning out, HDDs are only limited by their moving parts wearing down. They actually run longer, the less you cycle them on and off. We're making it so much more expensive for the average person to recover from a solar flare...

[@TwentyEightySeven]

I’ve always been a firm believer in HDD’s for longevity. SSD’s may be faster but they seem far less durable. As you said HDD’s theoretically have an unlimited amount of write cycles whereas SSD’s have an absolute finite lifespan. I have 25 year old HDD’s that still work fine. They also mostly start to fail slowly whereas SSD’s often die rapidly with very little hope of recovery.

TBW is actually to do with physics. Basically the NAND circuit in the SSD chip can only be cycled a limited number of times. The TBW grows with disk size as bigger disks reserve more 'spare' nand cells to use when some go bad. Simple free way to check your TBW is open a terminal window and type the command iostat -Id disk0 (that is a capital I and lowercase d) The last number is the number of bytes written since new. Divide by 1000000 to get TBW (actually 1048576 but a million is close enough)

That was before 2019 Macs- Now the BIOS is inside the NVMe.

How about adding TVS diodes to the SSD drive power lines? So if the regulator fails the TVS diode clamps the voltage and prevents the SSD from dying? Is there any sort of fuse on the power bus that will blow if the added TVS diodes activated? Would that be possible to add? Preventative maintenance is what I cam talking about here...

$800 for a 2tb ssd is the most jewish thing I have ever seen.

Regarding higher RAM and SSD lifetime - What you save on swap file you lose on hibernation.

what a painful video. Could have been 6min if it wasn't all about repeating the same sensational words over and over and over.

If you watch a lot of KZbin videos, the videos also get written to your SSD as it's buffered. I have no idea about other sites, but I do know for a fact KZbin does it.

1st of all. NEVER BUY MAC. IT IS TRASH. 2nd, only buy pc with swappable ram and ssd.

[@coldspring22]

Buy only old mac with upgradeable ram and ssd. But of course those old macs have already been "orphaned" by Apple. so you need to run windows on old macs.

Superb video. The information will help preserve the life of my SSD. Thank you very much.
