My M1 is suffering from a bug where there is runaway SSD writes and I have to restart it every few days. I've learned so many coping techniques. I'd never call this the best hardware I've ever owned, that was a 2011 MBA.
Yikes that sounds terrifying! What program is doing the writes? Apple or third party? Some demon going crazy with logging?
I've had my M1 Air since they launched, five years, and it doesn't show any sign of getting retired soon (except for the slight bend in my case where my lid jumped on it when it was open on the couch... but that mostly bent back.)
I had a 2011 MBA but vastly prefer everything about this one.
