You may have noticed a “ExpressCard” slot while shopping for a new laptop. ExpressCard technology is a fairly new technology that is expected to replace PC cards.

Compared to a PC Card

PC cards are more or less a PCI card for laptops. The PCI standard is being replaced with the PCI Express standard. Like in desktops computers, laptops will upgrade from PC cards to ExpressCards.

What’s the dif?

• PC cards can transmit data at 132MB per second and ExpressCard can transfer at 2.5GB per second.
• ExpressCards come in two widths, ExpressCard/34 and ExpressCard/54. The ExpressCard/54 is L-shaped and is the same width of the PC card. The ExpressCard/34 is about half the width of the PC card.
• The ExpressCard/34 will work in a ExpressCard/54 slot.
• PC cards will not work in ExpressCard slots.

Benefits

• ExpressCards use less power than PC cards which means less battery drain for laptop users.
• ExpressCards standard will be coming to desktop computers and an ExpressCard can be used on both your laptop and desktop computer.
• More powerful, faster, and better performance.
