Thanks to Apple's latest 5nm chip, M1 MAC has won a lot of praise for its performance and power efficiency,But there are also some shortcomings that have not been mentioned.
According to a twitter post by Hector Martin and Longhorn, their total number of SSD writes reached an abnormally high level in a few months. Martin claimed that his M1 MAC reported a total of 600gb of data written on SSD, and that he did not overuse the machine. Longhorn said that in just two months, his M1 Mac's 16GB of memory and 256gb of SSD writes have reached 1% of the total number of guaranteed writes.
One M1 Mac user with 16GB of memory and 2TB of SSD reported that the total number of bytes that could be written was 3%. He speculated that if it was a 256gb SSD, it might have used up 30% of that number. According to these calculations, the SSD will be completely worn out in two years, requiring customers to repair the MAC or buy a brand new Mac.
Although they are lightning fast, they can only handle a limited number of data writes until the machine starts to have problems. The larger the capacity, the more data can be written to the Mac. Apple's Mac OS platform can also ensure that the data written is evenly distributed on the flash chip to extend its service life, but at such a speed, customers may need to repair the machine as soon as possible. It's not clear whether the software made an error reporting the total number of bytes written, or whether Mac OS inadvertently caused the problem. Hopefully Apple will find out and investigate the problem.
