Note: Express Cards are third generation

desktop and mobile use, Express Cards 
use either USB 2.0 or a single lane PCI 
Express technology that provides 500 
Mbytes/sec total throughput. Formerly 
code named “NEWCARD,” Express Cards 
are 5mm thick like Type II PC Cards, but do 
not use the same 86x54mm footprint. 
Express Cards come in 75x54mm and 
75x34mm sizes. Express Card/54 slot 
means this notebook accepts 75x54mm 
Express Cards.
