eSATA 7-pin data connector

The seven-pin external SATA data form is documented on external storage cables; it is not a universal storage-power connection.

Also called external SATA e SATA 7 pin eSATA

External data and external power need separate evidence.

Look for

Look for the eSATA label and compare the external keyed housing with the device manual; do not substitute internal SATA by shape.

The useful distinction

Recognize it. Then verify it.

The seven-pin external SATA data form is documented on external storage cables; it is not a universal storage-power connection. [C118A]

The product is an external SATA storage data cable. [C118B]

The ESATA3 datasheet advertises a transfer rate up to 6 Gbps for this named external eSATA cable. [C118C]

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.

This field note does not approve a connection, publish a pinout or provide a measured template. Use the linked source scope and the checklist as a documentation starting point.

ESATA3: a cable with two eSATA ends.

The source identifies both ends as seven-pin eSATA. The qualitative study follows one visible oblique cable end; it is not a receptacle face or pin-number map. The advertised rate belongs to this cable’s documentation, not every similar connector or a measured storage system.
