PCMCIA Planned ExpressCard 2.0 During CeBIT计划中的PCMCIA ExpressCard 2.0在CeBIT展会
ExpressCard has been quite popular especially in newly release high end laptop. ExpressCard一直很受欢迎尤其是在新发布的高端笔记本电脑。 If you are not aware, it is a replacement for previous CardBus that is being integrated as part of the high bandwidth interfaces in today’s laptop architecture.如果你不知道，这是一种替代以前的启视录CardBus正在整合的一部分，高带宽的接口，在今天的笔记本电脑架构。 As compared to CardBus, ExpressCard is capable to support various bandwidth hungry applications such as wireless card, external hard disk and etc that require higher throughput for HD (High Definition) media streaming.相比启视录CardBus ， ExpressCard是能够支持各种带宽饿了应用，如无线网卡，外置硬盘等，需要更高的数据吞吐量为HD （高清晰度）流媒体。 Good news here is, there is a plan to upgrade the ExpressCard 1.0 to version 2.0, bringing even higher throughput for consumer market.好消息是，有计划升级了ExpressCard 1.0到2.0版本，使甚至更高吞吐量的消费市场。 
As compared to CardBus that is based on PCI interface, ExpressCard has been supported by both PCI Express and USB 2.0 bus for tremendous increase in total throughput.至于启视录CardBus相比，这是基于PCI接口， ExpressCard一直都支持PCI Express和USB 2.0总线的巨大增加总吞吐量。 Theoretically, current ExpressCard is able to scale up the total throughput to 2.5Gbps, two times more than what can be provided by CardBus at only 1.04Gbps traditionally.从理论上说，目前ExpressCard是能够扩大总吞吐量为2.5Gbps的， 2倍以上所能提供的启视录CardBus只有1.04Gbps传统。 With the introduction of new specification of version 2.0, it will able to boost the performance further up to 5Gbps by doubling PCI Express X 1 lane bus.由于采用新规格的2.0版本，它将能够提高性能进一步行动的一倍5Gbps的PCI Express × 1线公共汽车。 That is not even taking这不是即使考虑 USB 3.0 USB接口3.0 into consideration with potential of ten fold increment over existing USB 2.0 specification.考虑到与潜在的十倍，增量比现有的USB 2.0规格。
The ExpressCard 2.0 specification is expected to be released by end of 2008 or early of 2009.了ExpressCard 2.0规格预计将公布2008年底或2009年初。 However, the actual modules availability will not surface until after 2010.但是，实际的模块供应不会表面，直到2010年之后。 Good thing is, the new specification is backward compatible with version 1.0 so that you don’t have to worry about throwing away your old laptop when the new modules are being released.好消息是，新的规范是向下兼容1.0版，让您不必担心扔掉你的旧电脑当新的模块正在释放。
