8.4. Optimizing Data Transfers
Data transfers are the flow of data that accomplish-
es a task, usually related to moving data from storage
to computer RAM, or between storage devices. With
external drives, such as the LaCie LaCinema Premier,
the data is transferred from the drive to the computer
via the USB interface. The data is fed from the drive
through the USB port on the drive, and passes to the
computer through the USB host-bus adapter interface.
USB
■
To utilize the enhanced Hi-Speed USB 2.0 per-
formance, your computer must be equipped with a Hi-
Speed USB 2.0 host bus adapter card (either sold sepa-
rately, or integrated by your computer’s manufacturer)
and the appropriate drivers. These host bus adapter cards,
which include one or more USB ports, are shipped with
special Hi-Speed USB 2.0 drivers that enable the com-
puter to control the card. These drivers must be installed
in order for USB 2.0 devices connected to the port to
work at their correct speeds.
Computers running Windows 2000 and Windows
XP automatically manage Hi-Speed USB 2.0 devices
and drivers, while Windows 98 SE and Windows Me
will require that drivers be installed before a Hi-Speed
USB 2.0 device is attached.
Mac OS 9.x does not support Hi-Speed USB 2.0
functionality, and all Hi-Speed USB 2.0 devices will
only operate at the original USB specifications. Mac OS
10.2.7 and later supports Hi-Speed USB 2.0, and Mac
OS 10.x also supports Hi-Speed USB 2.0, but you will
have to purchase a third-party PCI or PC Card and ap-
propriate drivers.
