How SATA Works
Older G5 models used the PCI and PCI-X bus system. These cards are
longer than the newer PCI-E style bus used in the newer G5 dual and quad
core models. The pictures below show the difference in the Host Adapters
and the connectors.
PCI
Older G5 models use the PCI
type bus. The connector is longer
because this type of bus is known as
a parallel type, needing a larger
number of contacts.
PCI-e (Express)
Newer (late 2005) G5 models
use the PCI-E type bus. The
connector is smaller because this
type of bus is known as a serial type,
needing less contacts.
