Perhaps there is a hardware/firmware issue with the Sil3132, as this has 
been reported at a reputable Mac hardware performance site, see:

http://www.barefeats.com/quick.html

The December 23rd entry, "ExpressCard SATA bandwidth woes" mentions 
exactly this issue with an Express card using the Sil3132 and on a 
Sil3132 based SATA Adaptor card.

Richard
