Adaptec on Monday announced a USB (universal serial bus) 2.0 host adapter, capable of delivering up to 480 megabits of data per second. USB 2.0, which will replace USB 1.1, far exceeds the older standard's 12 megabits of data per second. The USB 2.0 host adapter--a PCI card--is compatible with the older standard.
USB 2.0 is expected to appear on new PCs later this year, setting up a possible showdown between IEEE 1394, or FireWire, which offers a maximum of 400 megabits of data per second. Apple Computer is expected to rachet FireWire to up to 800 megabits per second.
