ExpressCard 2.0 format nears completion
The ExpressCard 2.0 format is nearing completion, the PCMCIA trade group has announced. The existing format is a popular means of expansion on notebooks, such as Apple's MacBook Pro; the updated edition will be based on both the USB 3.0 and PCI Express 2.0 standards, and should be substantially faster, achieving two to 10 times the speeds of ExpressCard 1.x. This will make it better suited to storage functions, such as connecting flash memory or SATA II drives. Systems with ExpressCard 2.0 slots will remain compatible with v1.x peripherals.
A variety of companies have already announced their intention to support v2.0, including Dell, HP, Intel, Lenovo, Lexar, LG, Microsoft, Sony and Toshiba, among others. A finalized version of the standard should be ready in early 2009, but no products are expected until 2010, when USB 3.0 is due to premiere as well. More: Official Home Page for ExpressCard Technology from PCMCIA Press Release: ExpressCard Pressroom Addendum: USB 3.0 full specs promise 10X speed boost The USB 3.0 Promoter Group today revealed the full specifications for its namesake interface standard and so greenlit development of computer platforms and devices using the technology. The new peripheral format will now officially peak at 5Gbps, or about ten times faster than the 2.0 protocol. In actual tests, 25GB of data transfers in nearly 14 minutes over USB 2.0 but just 70 seconds over USB 3.0, significantly outpacing FireWire 800 as well as many hard drives. Some of the often-cited other limits of USB versus FireWire have also been tackled in the official 3.0 release. While it consumes less power overall, the spec also lets USB 3.0 push more power from the host to an attached device and should result in fewer external hard drives or other add-ons that need a separate AC power source to run properly. USB 3.0 is backwards-compatible with USB 2.0 hardware but won't work with USB 1.0 devices due to significant changes between the original format and its third generation, which comes more than ten years later. Hardware that supports USB 3.0 is still distant and won't show until the second half of 2009, when device controllers that can recognize and use the format are available. End devices also aren't due until 2010. FireWire isn't remaining static and should be upgraded to the S3200 standard ahead of USB 3.0 to provide about 3.2Gbps of bandwidth and similar power management features. |

Perhaps the EX5 will spot the SxS 2.0 :)

this isn't a firmware upgrade thing John, this is a chipset/boardset level thing ... hardware not software

Perhaps it will not make any difference since the Express card interface is not a bottle neck on the EX1/EX3. ;-)
