Have you seen one of those SSDs made by FusionIO? Those things fit in a
single PCI-e x8 slot and can easily push a sustained rate upward of
several GB/s. Do not expect that drives are the be-all end-all to
storage. Hybrid storage invalidated the traditional "CPU & memory fast,
disks slow" wisdom years ago.
