Intel's platform design guide (at least for its mobile platforms) calls for a SATA repeater/redriver chip immediately before the eSATA connector (or docking connector). It is however "passive" in the sense that is redrives the signal without appearing to the system whatsoever (just a receiver and re-driver inside the IC). I'd think that an eSATA drive with a stable power supply + a cable length within spec would be reliable enough for basic home use. --khd _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
