The M1 Macs may have received a ton of praise for their performance and power-efficiency thanks to Apple’s latest 5nm chip, but there were some drawbacks not talked about. For one thing, Apple doesn’t offer user-replaceable components as everything is soldered to the motherboard. Secondly, all M1 Mac models are limited to 16GB RAM, and if you use all that memory, programs will start using the SSD as the page file. Unfortunately, some owners are complaining of excessive wear on that SSD, which may lead to reduced lifespan of the machine.

A Twitter thread started by Hector Martin and Longhorn mention that the total write count on their SSDs have reached an unusually high value in a few months. Martin claims that his M1 Mac reports a total of 600GBs of data written on the SSD, and he doesn’t use the machine excessively. Longhorn claims that in just two months, his M1 Mac with 16GB RAM and 256GB SSD has written one percent of total warrantable bytes written.
