As someone who upgraded from an Intel Mac to an M1 mac, the memory is a non-issue. Three years ago I would have laughed if you said I would be happy with "only" 8GB, but now I am.
I thought I'd be happy with 8GB based on benchmarks and sensationalistic videos (thanks, Max Tech), but I absolutely wasn't. Apple silicon Macs or maybe Macs in general handle high memory pressure (graph in the red) terribly. The system will get extremely slow and laggy, develop audio issues and eventually lock up.
I ran into that all the time on the 8GB model (admittedly with multiple RAM-intensive apps and lots of tabs open), while it now happens very rarely on my 16GB model.
Is that high memory pressure slowness issue the same when there is lots of HD space left? Apple devices have had issues with “low” amounts of HD space for a long time, and I’m curious if the M* continue the trend.
Also: this makes a red flag of the recent shift to half-speed drive performance
