From what I've read, while the actual rpm might vary between models, any given model only spins at a constant rpm, thought to be somewhere between 5000-5900. WD isn't exactly clear as to what exactly "Intellipower" means 8-/...

"A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance. For each drive model, WD may use a different, invariable RPM."

So much for technical details, but that's the gist of it.
