@There0, PLEASE use the forum quoting features.. that's entirely incomprehensible!
There was a recent discussion on the OpenBSD mailing lists about E-SATA, any serious OpenBSD user would be monitoring such lists.
The basic conclusion, a SATA connector and a E-SATA connector are identical, if the SATA chipset is supported by OpenBSD.. and it happens to also have a E-SATA port, then it's supported.
Done. Question answered.
