PCI Express Explained
 

Bandwidth… We all want it and we all need it, but can we get enough of it? Well, PCI Express is here to satisfy our appetites for the next several years. PCI (Peripheral Component Interconnect) was originally developed by Intel Corporation, but is now slowly coming to an end, but probably won’t be entirely discarded for a couple of years. Why do we need PCI Express you might ask? Well, the PCI 2.2 bus and other revisions just don’t provide us with enough bandwidth to support the evermore demanding peripheral cards. Hard drive controllers and networking cards just aren’t providing enough bandwidth that some hard drives have the potential to offer.
