Depends on when you want to define "nothing to do with disk" as. M.2 was introduced in 2013 which would make them 9 years old by now, but if we look at Samsung's 2006 PATA SSD (with 32GiB!), then they'd be 17 and could well be on here.

Yeah I suppose there's a lot of wiggle room there. Personally I associate disks with circles because:

> In geometry, a disk (also spelled disc) is the region in a plane bounded by a circle. (wikipedia)

So you wouldn't find those in an SSD, it would have to be a spinning disk sort of deal.

I use a standard disk icon to represent "saving" in a popular web app I run. I very often see users referring to it with "click the square thing to save".

The “save” button is generally still a floppy disk as well!
