If the Mac is relying on the SSD for more processes than expected, it could explain why the SSD's usage seems to be so much higher than expected, particularly for models equipped with the basic 8GB RAM rather than the optional 16GB RAM.Įqually, the problem could be with the reported number. The swap file is an essential part of Unix-derived operating systems such as macOS. Hector Martin, a Linux developer for M1 Macs, said on Twitter that this issue could be due to macOS' swap-file function, which uses the SSD as a virtual RAM extension for intensive tasks. There's no way to replace it without swapping out several other parts, making repairs much more expensive than necessary. To make matters worse, this is an internal drive soldered onto the mainboard of the Macs. That's still higher than you'd expect for a brand-new device, though. Most users complaining about this issue are reporting figures of 2-3% usage, as seen on threads on the MacRumors forum and the LinusTechTips forum. But this rapid rate of use slashes that reliable life to less than two years. In theory, the SSDs in Apple's M1 MacBooks should guarantee reliable use for around five years. Compared to equivalent retail SSDs from Toshiba (who supplies the SSDs inside the MacBooks), that's equivalent to 10% of its total warrantied TBW. In the case of the tested Macs seen in these threads, one Mac Mini user claimed to have written 165TB of data in just two months of use.

This is a somewhat complex procedure that requires downloading a third-party app, so we don't recommend you try it yourself unless you're a very confident user. Mac power users have been checking how many bytes their MacBooks' SSDs have written by using an app called Smart Monitoring Tools, via the macOS Terminal.
