Few days ago we just mentioned about几天前，我们刚才提到的约 USB 3.0 Specification的USB 3.0规格 has been finalized and released to developers, now Express card version 2.0 standard which is based on the newly defined USB 3.0 as well as PCI Express 2.0 specification has also reached another new milestone.已定稿并发布给开发商，现在Express卡2.0版标准，是根据新界定的USB 3.0以及的PCI Express 2.0规格也达到一个新的里程碑。 Either one, which offers much higher throughput scaling from minimum of two times up to ten times as compared to current version 1.0 will definitely attract board makers to design it into their next generation notebook PC.一方，它提供更高的吞吐量规模从最低的2倍至10倍相比，目前的1.0版本肯定会吸引主板厂商设计到其下一代笔记本电脑。
ExpressCard standard has penetrated well with estimated 95 percent of market share in notebook segment. ExpressCard标准已经渗透以及估计百分之九十五的市场份额在笔记本电脑市场。 Some of its current applications include wireless Ethernet module, TV tuners, serial ATA adapters, smart card readers and much more.它的一些现行的应用包括无线以太网模块，电视调谐器，串行ATA适配器，智能卡阅读器以及更多。 And with the finalization of the USB 3.0 specification, it allows PCMCIA to move one step further working on Express card version 2.0 compatible products.与定稿的USB 3.0规格，它允许的PCMCIA移动一步工作的Express卡2.0版本的兼容产品。
Theoretically, current ExpressCard can provide the total throughput with up to 2.5Gbps, which is around two times more as compared to conventional CardBus at only 1.04Gbps.从理论上说，目前ExpressCard可提供总吞吐量高达2.5Gbps的，这是大约2倍以上相比，传统的启视录CardBus只有1.04Gbps 。 Now with version 2.0, we expect a further performance boost of up to 5Gbps by having two PCI Express X 1 lane bus.现在， 2.0版本，我们期待进一步的性能提升高达5Gbps的有两个PCI Express × 1线公共汽车。 That is not even taking USB 3.0 into consideration with potential of ten fold increment over existing USB 2.0 specification.这不是即使考虑的USB 3.0考虑到与潜在的十倍，增量比现有的USB 2.0规格。
Similar to USB 3.0, ExpressCard 2.0 specification is backward compatible with its previous version and is expected to be released by early 2009 with the actual prototype readiness by 2010.类似的USB 3.0 ， ExpressCard 2.0规格向后兼容以前的版本，并预计将公布的2009年年初与实际原型准备到2010年。
