Finally Silicon Image have released 10.6 compatible drivers for their Sil3132 chipset which includes my Lacie dual channel eSata ExpressCard
eSata expresscard has been a disaster since Snow Leopard came out and now my machine is running its external drives back at full speed.
Why Apple didn’t put an eSata connector on the laptop is a mystery, especially given that its on the motherbaord as the internal drive is SATA.
