I'm not sure how good such exact numbers would do. Surely power down behaviour that would depend on the exact disk/controller/system combination? Some might be better at getting data out at power less, some might be worse. To get a good picture, you would probably need to do such tests over a wide range of systems and put all the data together, but even then you couldn't be sure you covered all well. For a distributor it would probably make more sense to do such tests as part of system certification and then modify the defaults to match all tested systems. But that doesn't really work for good mainline defaults. I suspect for mainline the only good default is to be very conservative. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
