A conventional PCI bus (not PCI Express or such) at 64bit @ 66mhz has a max transfer rate of around 533MB/s. That being Megabyte, not bit.
USB has a transfer rate of 12mb on regular and 480 on high-speed mode. That is megabit, which is much less then MB per second.
PCI in this case, compared PURELY on speed, is much faster.
In general, yes. USB 2.0 is about one-third the speed of the PCI slots found in most computers (32-bit, 33 MHz). USB 3.0 will be approximately 5 times faster than those same PCI slots. However, as of December 2009, no production USB 3.0 hardware is available.
The PCI slot is faster. Offer mayor speed because the PCI use more faster BUSes and new architectures. The PCI EXPRESS is the newest version of the PCI architecture.
A USB PCI card can be purchased from many different stores and retailers. Some examples that sell USB PCI cards include Dell, Newegg, CDW, and Walmart.
you can purchase and install a pci card that has the current generation of usb to allow faster transfer to devices that also support the new version. The newest version is usb 3 and the ports are blue
You can download a driver for a hi-speed USB controller that is already installed. You cannot, however, download any software to make an older USB controller faster.
Typically it is a usb port 2.0.
PCI Express
PCI Express bus standard or the USB 2.0 standard
Yes, you would have to purchase a USB, PCI, or PCI-X wireless device/card.
PCI-X is an extension to the original PCI slot. It uses a 64-bit data bus (most but not all PCI slots are 32-bit) and runs much faster than PCI (PCI runs at 33 or 66 MHz, PCI-X ranges from 66 MHz to 533 MHz). PCI cards can be used in a PCI-X slot, and most PCI-X cards will run in a PCI slot.PCI-E (PCI Express) is a totally different architecture. The connectors are similar, but PCI-E is a serialized bus, whereas PCI and PCI-X was parallelized. In PCI-E, there are fewer data paths but the paths run much faster. Think of it as the difference between a six lane highway with a speed limit of 35 MPH vs. a two lane highway with a speed limit of 75 MPH.
PCI express is faster
Boards have evolved over the years. They started out with 1 , then went to 2 on up to about 6. As they evolved they have gotten to be fewer with the advent of pci xpress. My mother board has one PCI and 2 PCI xpress. As more devices utilize the USB bus, card slots become less necessary. Most any device on a PCI card can be found on a USB device.
