Flash is indeed a weak link. I use to put together embedded Linux systems out of commodity server components 15 years ago, and over the years we lost many flash chips (altho they would often continue functioning in a degraded state… read only) due to the high logging rate of Linux combined with the low write endurance of typical usb flash disks. You can get more expensive single level cell (or pseudo-single level cell) chips now that can last an extremely long time. Old Tesla Model Ses had this same problem with the infotainment system flash, but Tesla will fix it for you for free now since the infotainment system contains some features NHTSA considers safety essential (wipers, etc).
