Enter the IEEE 1394 architecture and its close kin FireWire, which takes the high-speed digital bus interface up to the wicked fast transfer rate of 400MB per second.
It boasts the industry's highest density as well as the highest performance level of 400 megabits-per-second (mbps) data transfer rate based on the toggle DDR 2.0 interface.
As PCIe products move from Generation 2 to Generation 3 with a doubling of the data rate per PCIe communications lane, flash based storage devices using this interface as their data transfer backbone will enable very high performance systems.
