4. Interface & Data Transfer Information
4.1. USB 2.0 Connection
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 nec-
essary bandwidth and data transfer rates to support high speed
devices such as hard disks, CD/DVD drives and digital cameras.
USB cables
Your LaCie drive is shipped with a Hi-Speed USB cable to ensure
maximum data transfer performance when connected to a Hi-
Speed USB 2.0 port (Fig. 10). The cable will also work when con-
nected to a USB 1.1 port, but drive performance will be limited to
USB 1.1 transfer rates.
4.2. FireWire Connections
FireWire 400, also known as IEEE 1394, is a high-speed serial
input/output technology for connecting peripheral devices to a
computer or to each other, and FireWire 800 is the implementa-
tion of the new IEEE 1394b standard.
FireWire 800 offers increased bandwidth and extended cabling
distance between devices. FireWire 800 is ideal for bandwidth-
intensive applications, such as audio, video and graphics.
FireWire Cables
Your LaCie hard disk is shipped with a FireWire 800 (9-9 pin)
cable (Fig. 11) and a FireWire 400 to 800 (6-pin to 9-pin) adapt-
er cable (Fig. 12), which will allow you to connect your drive to
your computer’s FireWire 400 cable. Note that in this case, file
transfers will be limited to FireWire 400 speeds.
