The chip is not even worse a few dollars currently. It just shows fundamental stupidity of designers not making it replaceable flash card. You can get 2TB high speed multi-stream flash microSD for $300 today. I doubt there will be many takers in US though, folks just not going to take a risk.LeftieBiker said:I expect that Tesla-oriented aftermarket shops will start offering to just replace the flash memory chip for half the $1800 price or less. The chip itself is probably worth about $50.

They're not that short. Good SSDs have many dies and the writes can be spread out across them. Also, if you don't completely fill the drive and leave some room as buffer, that can help.LeftieBiker said:This is why SSD drives have yet to replace traditional hard disk drives in most computers: they trade speed for a relatively short "write-span."
The shop near me (Electrified Garage) roots the car and lowers the logging level to reduce the number of writes. They also replace the part for much less than that.LeftieBiker said:I expect that Tesla-oriented aftermarket shops will start offering to just replace the flash memory chip for half the $1800 price or less.

They replace it, but with used one from salvaged one, so the issue would come back.jlv said:The shop near me (Electrified Garage) roots the car and lowers the logging level to reduce the number of writes.

When I spoke to Chris (the owner there), he told me they turn the Linux logging off, which avoids the problem.Leaf15 said:They replace it, but with used one from salvaged one, so the issue would come back.
cwerdna said:I've switched over to a newer PC I built in mid-2018 w/a different SSD (Samsung 960 Evo 500 GIG). 8.9 TB has been written to it so far. Per https://www.samsung.com/semiconductor/minisite/ssd/product/consumer/960evo/, they warrant it for 3 years or 200 TBW. Per https://www.anandtech.com/show/10833/the-samsung-960-evo-1tb-review, it's TLC. This PC will likely be retired before the drive hits 200 TB of writes.
“The main issue is that this excessive log file writing causes eMMC flash wear. Flash memory is generally only rated for some tens of thousands of write cycles. What happens is that the flash memory starts to fail when writings can no longer be completed. When one block fails, parts of the firmware may also become unreadable, leading to poor operation or failure of the MCU completely.”

operational parameters, and basic logging functions requiring very frequent memory writes? The MCU system should have had two separate
flash memories.
