The age-old assumption that I/O is slow and computation is fast is no longer true. This invalidates decades of design decisions that are deeply embedded in today's systems, and requires rethinking the compute/storage balance and architecture from the ground up. The arrival of high-speed SSD and other high speed non-volatile storage (Storage Class Memories, or SCM) is likely the most significant architectural change that datacenter and software designers will face in the foreseeable future, according to this paper in ACM Queue [acm.org].
