I understand it runs slower than the internal M1 SSD, but with 8GB of RAM you can upgrade via swap space. The system uses the main drive for swap, which I prefer not to do since it may reduce the SSD’s life. Windows supports external drives as virtual memory. Is this feasible on a Mac? Please let me know. On the screenshot it appears only 242MB was written, yet before that the swap used nearly 17GB when working with images in Pixelmator Pro.
Based on the calculations, the Mac should still function for another 16 years. (I purchased it in May and it’s now December, meaning I’ve used it for 7 months so far. The typical TBW is 300TBW on a 256GB SSD. Over those 7 months, I’ve written about 4.8TB. Uploading a session would extend its lifespan beyond 10 years.)
