TITLE:
The Disk is Dead! Long Live the Disk!

ABSTRACT:
Recent declines in RAM prices have made it reasonable to discuss replacing disks with battery-backed RAM as the primary persistent storage medium in desktop computers. RAM has already taken over in some areas (such as PDAs), but disk is still the only reasonable choice for most large-scale applications. In this talk, I will describe Conquest, a hybrid disk/RAM filesystem that combines the best of each medium while providing a transition path toward the day when disks can be discarded. Surprisingly, Conquest outperforms disk-only filesystems in its disk mode, RAM-only filesystems in its RAM mode, and cache-backed filesystems in any mode.
