My home computer's SSD just suddenly failed. No warning. Walked into the room to see the BSOD. Reset... "Hard Drive Not Found"

Pull plug, power back up: "Hard Drive Not Found" (Oh no!!!)

I'm just wondering if it's more common for "errors" to occur before an outright "toes-up" failure, or are we sometimes just going to get broadsided like this?

Remember that SDDs are *not* hard drives.  Rather, they are assemblages of integrated circuits that mimic a ‘real’ hard drive —i.e. spinning magnetic media — to the OS.  Like most things solid-state, they tend to fail catastrophically and without warning.  The failure modes are quite different from magnetic media, where failure is often due to mechanical wear that can be detected incrementally over time and appropriate warnings generated.

Bottom line: there’s no substitute for backups!
