ExpressCard Dimensions

The ExpressCard standard define two form factors, the 34mmm wide ExpressCard/34 and the 54mm wide ExpressCard/54.
Whilst the 34mm slot accepts only 34mm cards the 54mm slot accepts both 34mm and 54mm cards. Brainboxes ExpressCard range being 34mm wide will fit into any ExpressCard slot on your laptop computer.

Brainboxes ExpressCard technology has several advantages over the older PCMCIA card technology, the four main ones being:

  • ExpressCards that are about half the size & weight
  • ExpressCards give longer battery life by using a lower supply voltage and having improved power management
  • ExpressCards offer a better user experience being based upon USB’s leading edge plug and play mechanism.
  • ExpressCards are lower cost due to their smaller size and higher integration parts.

 

PC Card - PCMCIA

ExpressCard dimensions

PCMCIA stands for Personal Computer Memory Card International Association, the group of companies that defined and developed the standard. While this acronym did clearly describe the original intentions of the organization's standard, it was difficult to say and remember, and was sometimes jokingly referred to as "People Can't Memorize Computer Industry Acronyms". Later PCMCIA was rebranded to simply PC-Card. PC-Cards were superseded by ExpressCards in 2003, laptops manufactured after this time are more likely to have ExpressCards.
