Q: Can I use Digi Acceleport Xr 8-port in PCI express slot?
Q: What is the difference between PCI Express X1 and PCI Express X16?
Q: Can you use an AGP card in a PCI express 2.o slot if you use PCI express drivers?
Q: Is there a way to tell if my computer has a PCI Express slots without opening it up?
A: Unfortunately the best way to find out if you have a PCI Express slot is to open up your computer. You can, however, figure out if you have one without opening up your computer by looking at the manual that came with your computer or your motherboard. The problem with that is most people don’t keep their manuals but if you are the type that does then you are in luck! Just open it up and read though it and it should tell you.

Q: What transfer speeds can I expect to get when using FireWire 800 interface cards? For instance, a FireWire 800 to PCI isn’t going to get you 800 MB per second, is it? Likewise, PCMCIA has speed limitations. These device manufactures don’t bother to provide details on interface limitations.
A: Excellent question! As you know, most computers do not have FireWire 800 built-in. Part of the reason for this is that FireWire 800 connections are often faster than the devices to which you are connecting. For example, traditional hard drives read/write data at speeds far below FireWire 800′s capabilities. Additionally, the Front Side Bus in many computers is too slow for FireWire 800.
But because FireWire 400 is slightly slower than many external devices, FireWire 800 is a great technology for many multimedia professionals. If you own a desktop computer, you will probably achieve the fastest FireWire 800 speeds by using a PCI Express card. For best laptop performance, you should use ExpressCard technology. The links below will help you to select the best Firewire 800 card for your situation.

Tip: Although I and many other geeks feel that FireWire-based technology is superior to USB-based technology, Apple (the main creator of FireWire) and other companies are abondoning FireWire-based technologies in favor of USB-based solutions such USB 2.0 and the upcomming USB 3.0. Invest in FireWire-based solutions at your own risk!
