With all the gadgets and devices we post about, there’s plenty of merit in veering a little closer to some USB hardware fundamentals and how it communicates with your computer. To highlight this importance, a UDISK Drive and its internal functionality will serve as a comparison.
Simply put, a UDISK is a hard drive in USB form. With magnetic hard drive platters spinning inside an enclosure, UDISKs have a bridge chip regulating the way the drive mounts to an operating system. This chip changes the hard from from IDE protocols, to USB. Standard USB drives don’t use rotating disks to store data, but use flash memory instead, which enjoys faster speeds as well as increased reliability against shock, pressure, and temperature. Why then do these UDISK drives exist? Because those spinning disks are cheaper to manufacture but they can be sold at the same price as standard flash memory USB drives and the difference may not be clear to users.
