I have a MacBook Pro and I have just ordered an external hard disk which will have an esata interface as well as USB 2.0. I know that esata can be a lot faster than USB 2.0 but I remember reading (unfortunately I cannot find where I saw it) that the expresscard/34 slot in the MBP has a USB2.0. Go to the directory where the file was downloaded and double-click the XQDDrvInstallermac.zip file to begin the installation. Follow the the on-screen instructions. Once the installation is complete, if prompted, click the 'Restart' button. After the computer restarts, insert a XQD memory card into the ExpressCard slot on your computer.

I have a MacBook Pro and I have just ordered an external hard disk which will have an esata interface as well as USB 2.0.
I know that esata can be a lot faster than USB 2.0 but I remember reading (unfortunately I cannot find where I saw it) that the expresscard/34 slot in the MBP has a USB2.0 data interface rather than PCI Express.
Is this true? If so, presumably there would be little benefit in buying an esata expresscard to connect to my external drive rather than just using USB.
Am I correct in this or have I misunderstood something (which is perfectly likely)?

Express Card Slot For Macbook Pro

Replacing PC Card and PC CardBus, PCMCIA introduced the ExpressCard standard, which is available now in a range of host systems like Sony's VAIO VGN-FE790 and Apple's MacBook Pro. Supporting both the PCI Express and USB 2.0 standards, ExpressCard is faster, smaller, and easier to implement than the preceding PC Card expansion technologies.

ExpressCard's speed and flexibility allow for exciting applications such as full throughput FireWire 800 host adapters and UDMA 4/PIO Mode 6 supporting CompactFlash adapters. In time ExpressCard will supplant PC Card entirely as more host systems and peripherals come to market. Particularly exciting is the prospect of ExpressCard slots and desktop machines for PCIe 1X applications, as it would alleviate the need to open a system's case to install new functionality. Synchrotech intends to carry the broadest possible range of ExpressCard technology.
