1.5. Cables and Connectors
1.5.1. USB 2.0
USB is a serial input/output technology for connecting peripheral
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 en-
sure maximum data transfer performance when connected to a Hi-
Speed USB 2.0 port. The cable will also work when connected to a
USB port, but drive performance will be limited to USB 1.1 transfer
rates.
1.5.2. FireWire
FireWire 400, also known as IEEE 1394, is a high-speed serial in-
put/output technology for connecting peripheral devices to a com-
puter or to each other, and FireWire 800 is the implementation of
the new IEEE 1394b standard.
FireWire 800 offers increased bandwidth and extended cabling dis-
tance between devices. FireWire 800 is ideal for bandwidth-inten-
sive applications, such as audio, video and graphics.
Included FireWire Cables
Your LaCie hard disk is shipped with a FireWire 400 cable and a
FireWire 800 cable.
