I was surprised, but yes. And as expected, bus limits it performance badly. But it is still works much faster then 3132 at the same bus. >>> - First generation of SiI chips (SiI3114).

It is already possible in HEAD to write quirks for specific device models and firmware revisions. Also to control NCQ usage. -- Alexander Motin
