Some advanced users have been reporting an overuse of the SSD for writing and reading data on the newly released Macs with M1, Apple’s first computer chip based on ARM architecture. The issue could eventually affect the lifespan of the internal SSD used in M1 Macs — not to mention the machine itself.

As noted by users on Twitter and also on the Linus Tech Tips forums, macOS indicates that the internal SSD of M1 Macs has registered “extremely high drive writes over relatively short time.” One user points out that in some extreme cases the SSD has already had consumed about 13% of the maximum warrantable total bytes written (TBW).

我的M8SeGN3年才写入了TBW的4%；有的M1 Mac，3个月就写入了TBW13%，mac OS 11对内存和swap的调度必然是有鬼。
