Now we wait for devices to show up

Several years ago when PCI-Express was being developed, the technology was also being designed to support devices outside of the traditional computer enclosure. While "internal" PCI-Express took off, development and support for external devices was slow. This week, the PCI Special Interests Group (PCI-SIG) announced the availability of the PCI-Express external cable specification revision 1.0.

With the new specifications fully defined, cables will be developed for all PCI-Express link widths including: x1, x4, x8 and x16. This allows for devices such as external high-speed storage controllers, network or fabric interfaces and graphics adapters to use the technology.

According to PCI-SIG chairman Al Yanes, external PCI-Express products should now be in full development and show up on the market in less than a year. "This specification helps the industry create new products that will take PCIe technology out of the box – enabling PCIe solutions for IO expansion drawers, external graphics processors, tethered mobile docking, communications equipment and embedded applications,” said Yanes.

External PCI-Express devices will be able to use signaling rates up to 2.5 gigatransfers per second (GT/sec). Of course, the host, adapter and cable must be able to support those speeds, but the future looks promising according to the specification's outline. Later on, 5GT/sec. rates will be possible. Some applications for this type of technology include stacking storage arrays together by using the external PCI-Express interconnect rather than relying on Gig-E networking.

RE: PCI-E internal took off!

Yeah, I agree here. really, pci is a more than fine enough interface for companies like creative. I purposively looked and bought a motherboard that would give me more usable pci's and a lot less pcie slots. they are 100% useless. In fact, I need another slot for a radio broadcast program and am debating how to move my water cooling stuff around so that I can utilize the last one.

pci-e slots = useless except for spoiled brats with mommy buying them a sli or crossfire setup so they can frag n00bz.
