■ eSATA
Your LaCie d2 Quadra Hard Drive uses the latest
in SATA technology, allowing interface (or bus) transfer
rates of up to 1.5 Gbits/s. SATA technology was
originally developed to serve as an internal interface, delivering
improved performance to internal connections.
Soon after, eSATA, or external SATA was developed,
allowing for the use of shielded cables outside the PC.
eSATA technology was developed to be rugged and
durable. eSATA connectors do not have the “L” shaped
design of other SATA connectors. In addition, the guide
features are vertically offset and reduced in size to prevent
the use of unshielded internal cables in external applications.
Please see page 39, eSATA Questions And Answers
for more information on eSATA’s uses and capabilities.

transfer rate
Plug orientation – An extrusion on the outside of
the connector helps guide and align the connector
during insertion.
Hot-plug support – eSATA enables adding and
removing a drive without having to power down
the system or reboot. Utilizing staggered pins to
aid insertion, the specification ensures device detection
and passive and active limits to in-rush
current.
TeChNICAl NOTe: You can connect your d2
Quadra to a first-generation SATA PCI card interface.
However, you will need a SATA-to-eSATA
cable (not included).
For more information on the differences between
the d2 Quadra’s interfaces, see chapter 4.2. Interface
Comparison.
