1.4.2. USB Cables and Connectors

USB is a serial input/output technology for connecting periph-
eral devices to a computer or to each other. Hi-Speed USB 2.0
is the latest implementation of this standard, and it provides the
necessary bandwidth and data transfer rates to support high
speed devices such as hard drives, CD/DVD drives and digital
cameras.

Included USB Cable

Your LaCie drive is shipped with a Hi-Speed USB 2.0 cable, to
ensure maximum data transfer performance when connected to
a Hi-Speed USB 2.0 port. The cable will also work when con-
nected to a USB port, but drive performance will be limited to
USB 1.1 transfer rates.
