"Selection bias" would infer I'm doing some kind of formal analysis,

Nope - the only thing 'selection bias' says is that inferences drawn from a 
non-representative dataset will also be non-representative.

Drawing an inference of 'raid rebuilds are slow' from a mailing list people 
come to when they need to report an issue will overemphasize problems and 
deemphasize cases where everything is working properly.

Also, no matter how quickly a rebuild goes, it's still longer than people 
would like. No matter how quickly it finishes, you're still in a stressed 
state where something has _already_ gone wrong and your parachute is now in 
use and unable to save you a second time.
