Adapter components
Using the correct eSATA cable
Note: Make sure that you have the correct eSATA cable to
connect your external SATA device to the PCI Express adapter.
There are two types of SATA cables available, which are used for different
applications. The internal SATA type A cable has an L-shaped key on each
plastic plug. This type of cable is used with an internal SATA port to
connect an internal SATA drive.
The external eSATA cable has a shielded plug, which does not have an L-
shaped key. The eSATA cable is designed to connect an external SATA
device, so it must therefore provide better EMI (electromagnetic
interference) and ESD (electrostatic discharge) prevention. This type of
cable is capable of a fast data transfer rate of up to 300 MB/s.
The following picture can help you to recognize both standard SATA and
eSATA cables. If you do not have an eSATA cable, you must purchase one
from your local dealer.
