Mac users are reporting dangerous behavior on their M1-powered Macs – including Apple’s latest Mac Mini, MacBook Air, and 13-inch MacBook Pro models – leading to severely shortened lifetimes of their internal storage drives . If the glitch continues, users expect the solid-state drive (SSD) on the Mac to last just two years. The problem is particularly notable on Macs where the storage itself is not user-replaceable, which will either lead to costly repairs or complete replacement of the entire computer if the drive fails prematurely.
Users of Apple’s latest M1-powered Mac are stating that extremely high drive writes in a very short time, and in the most extreme cases result in about 10-13% of the written total bytes or TBW of SSDs, an iMore report According to. In about two months, a user mentioned that M1 Mac had already used 1% of SSDs, while Twitter users Hector Martin Mentioned that on its 2TB system, the Mac used 3% of the SSD.
This led to speculation that if it had been a 256GB model instead of a 2TB Mac, the percentage used could have been up to 30%. This means that the system would have reached its maximum TBW in two years.
Update on the M1 SSD wear issue: Available data suggest that writing endurance ratings are not proportional to drive size.
256GB model: ~ 2000TB [1700-2300]
2TB Model: ~ 5000TB [4300-6000]
it means that @david_ryskThe currently known worst case will increase the 256GB model by 100% in ~ 2y

It is also unclear whether the problem is different from M1-powered Macs, or if older Intel-based Mac systems are susceptible to this erratic storage behavior. Twitter user Dark-Phoenix confirmed that they are running out of space due to unusual usage on the old 2016 MacBook Pro, which is powered by Intel.
“On my MBP (15-inch, 2016) I use for work,” dark Phoenix wrote. “I have all this backup, but still my use is unusual because I do a lot of data processing and rarely have free space.”
It appears that the problem may be software-related, rather than an issue with Apple’s custom M1 silicon functions.
Martin said in a later tweet, “Intel Macs are also qualified, if you can measure up to the time that you’ve owned it and it looks crazy,”. “Clearly 100TB in 4 years is appropriate.”
However, it is still unclear whether this glitch exists because the system made an incorrect recording, or if it is a major problem related to MacOS, which is writing redundant data to the drive. Often, drive monitoring tools can often inaccurate diagnostic information, and given the newness of the M1 chipset, there may be some compatibility issues with the tool or with other applications that do not behave properly in the background.
Although SSD degradation is a common process that occurs over time with regular usage, large-scale writing of data into memory and filling it to capacity can cause storage instability and drive failure. Modern operating systems, such as Apple’s MacOS when functioning properly, will attempt to maintain the integrity of the drive by spreading the load across the drive to prevent only a select portion of the drive from being overworked.
Whatever the case may be, Apple may address issues before refresh more Mac systems with the M1 chipset. Apple’s Mac Pro and iMac desktop are rumored to be overshadowed this year, joining the much-awaited redesigned 14- and 16-inch MacBook Pros.
