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.

Somehow I've been extremely happy for 2 years with my Athlon 3400+ and 1GB RAM notebook. And even now I couldnt wish for more.
It rips a DVD in 3 hours at excellent DivX quality, it records YouTube videos from screen capture at full frames, it plays any game underclocked at 1500MHz, it converts from MP3 to Audio CD in realtime and writes the CD in 5 minutes, in 10 minutes it writes a full DVD, the wireless adapter works at 2-3 MB/s never the bottleneck in internet connection, it executes and debugs .NET apps immediately and in realtime, and the same is true for PHP script and database queries, it even handles all the flash and javascript of the web fluently just like the developers intended the experience to be. And I can do all that without getting out of bed... or 100 miles away from home.

What I'm not happy with is the Radeon 9600. Very few games can it play anymore. I usually have a plug nearby wherever I go, so power is not a problem for me. Let me use a Radeon 1950 for my notebook and I'm good to go for another 2 years with this baby.
