There isn't one. You can run it against a filesystem mounted off a
specific disk, but that's not going to give you a similar answer.

Ignore this.

It's not. You are trying to measure something you don't really
understand, and the results are just going to confuse you. Rather than
worrying about whether you're getting the last 0.03% out of your machine,
go for a walk in the sunshine. It'll extend your lifespan proportionate
to at least a 20% improvement in the performance of your system. 8)
