#P2 card reader usb serial
Rather than a 68-pin parallel connection used in PC Card, ExpressCard utilizes a 26-pin beam on blade serial connection. ExpressCard is a serial rather than a parallel bus ExpressCard follows the trend of PCI Express and SATA in transitioning from parallel buses to serial buses.

This allows systems deploying ExpressCard technology to take full advantage of current low power utilization throughout. ExpressCard has superior power saving and management ExpressCard operates at lower voltages than PC Card with 1.5 and 3.3V baselines. Additionally, ExpressCard will be able to handle the latest SATAe and other high end buses with relative ease. Examples of full throughput host adapters that bottlenecked CardBus, but don't tax ExpressCard at all are FireWire 800 (IEEE 1394.b) and Gigabit Ethernet (GbE). ExpressCard allows for much more bandwidth ExpressCards featuring PCIe 1X technology are capable of 2.5Gb/s per direction, allowing for realization of applications, especially host adapters, that underperformed or were impossible under PC CardBus. ExpressCard alternatively utilizes USB 2.0 for lower speed and less complex applications, with a maximum throughput of 480mb/s. ExpressCards featuring PCIe 1X technology are capable of 2.5Gb/s per direction, giving an ExpressCard operating in full duplex mode an approximate throughput of 250MB/s x 2, or 500MB/s of throughput, nearly quadrupling the effective speed of 32-bit PC CardBus. Differences between ExpressCard and PC Card ExpressCard features new interconnect technology ExpressCard utilizes two interconnect technologies, the most important of which is PCI Express ( PCIe). ExpressCard holds several advantages over PC Card some of which are enumerated below. Are any Thunderbolt solutions for ExpressCards?ĮxpressCard is PCMCIA's (subsumed by the USB- IF) portable, removable, expansion technology to replace PC Card and PC CardBus (sometimes mistakenly called PCMCIA Cards).Are any hot-swap capable external solutions for SxS ExpressCards?.Is it possible to add ExpressCard slots to computers with PCIe?.How does ExpressCard 2.0 differ from ExpressCard?.Is there a way to stabilize ExpressCard/34 inside ExpressCard/54 slots?.Is PCMCIA PC Card forward compatible with ExpressCard?.Is ExpressCard backward compatible with PCMCIA PC Cards?.Differences between ExpressCard and PC Card.ExpressCard FAQ for ExpressCard 34 and ExpressCard 54 Contents
