Why express card?
DWA643 Xtreme N Notebook ExpressCard
The major benefit of ExpressCard technology over the previous PCMCIA CardBus is a dramatic increase in bandwidth, afforded by the fact that the ExpressCard has a direct connection to the system bus over a PCI Express x1 lane and USB 2.0, whereas CardBus utilizes an interface controller that only interfaces with PCI. The ExpressCard has a maximum throughput of 2.5 Gigabits per second through PCI Express and 480 Mbps through USB 2.0 dedicated for each slot, versus CardBus’s shared 1.06 Gigabits per second bandwidth. In addition, the ExpressCard standard uses lower voltages than the previous CardBus slots (1.5V and 3.3V versus 3.3V and 5.0V).
ExpressCard Benefits
1. Up to 236% faster than legacy CardBus
2. Approximately half the size and weight of a standard CardBus adapter
3. Provides superior performance, better reliability, and expansion flexibility over CardBus2
