Updating usb

You should never purchase a USB 3.0 expansion card that lacks a power adapter as the PCI expansion slot cannot supply enough power to meet the demands of a fully loaded USB 3.0 card.In the photograph below you can see the molex power port, the 4-pin/milky white port on the right, on the Hoo Too-PC002.The third item in the list is a bay expansion that allows you to turn an unused 5.25″ drive bay into a USB hub and media card reader.There are two important considerations when purchasing a USB 3.0 expansion card.If you already have a USB 3.0 port or two on your computer, you can pretty much skip this section: you already know how great USB 3.0 is and you’re here for more.If you’re thinking about upgrading an older computer to support USB 3.0 you might not realize just how many improvements USB 3.0 offers over USB 2.0. The maximum theoretical speed of USB 3.0 is ten times faster than USB 2.0.This tutorial is slightly different in that there are several ways you can go about upgrading computers both old and new to support USB 3.0.Rather than list off every potential combination of hardware add-ons and their permutations, we’re going to highlight two very common upgrade paths.

The new case sports a USB 3.0 port built right into the front port panel but, alas, the circa-2006 motherboard doesn’t support USB 3.0 and has no 19-pin header for the case cable to plug into.Same hardware, same disk size, different USB ports and standards.In addition to significantly increasing the speed, the USB 3.0 standard introduced better bandwidth management (USB 3.0 devices and connections use two omnidirectional paths instead of the one-way communication available with USB 2.0), better power management, improved bus utilization (which translates to faster at-ready times when new devices are added to the host computer), among other minor but welcome improvements.This tutorial will cover the upgrade process for desktop computers.This tutorial will not cover the upgrade process for laptop computers as laptops are difficult to upgrade to USB 3.0.
