YES

And I'd want to see failed drives somehow organized by TimeInService and maybe origin...

We of course expect their drive usage to grow, but what would be surprising (& provide more info) is how the drives fail or age-out. None of us without huge data centers can get that kind of info

I'd like to do another vis that includes failed drives. Please, keep helping me brainstorm.

Yeah, I think it would be a cooler visualization if the drives were in a line instead of a circle and new drives are added on to the right. The failed drives pile up on the bottom.

Still fun to watch as it is, though.
