The SiI 3132 is the chip type.

The chip may be operated in two modes: RAID mode and BASE mode.

Most of the PCI-E cards, which are used in desktops, are RAID mode,  
although some can be FLASHed to be BASE mode (BASE mode simulates an  
IDE drive to the host).

When used as n Express-34 card in a laptop, the card provides two  
eSATA (external SATA) ports, which are identical to the ports found  
on a PCI-E card.

Most of the Express-34 cards are BASE mode, and I am unaware of those  
which can be FLASHed to RAID mode as this requires a DOS system,  
although a Win-32 FLASHer is also available (a MacOS FLASHer is NOT  
available).

As I stated SiI3132 is included in many MacOS distributions, and if  
it is not, then the MacOS installer is freely available from the SiI  
web site.

After you insert the Express-32 card, you may then insert one or two  
eSATA (external SATA) cables (not generally included with the card),  
and each of the two ports supports a port multiplier, which provides  
for a five-to-one expansion of the available storage on each port.

It is thereby possible to connect 10 TB of external storage to a  
laptop, using a simple Express-34 card.

You need not buy a special Mac card, either. Just look for the  
Silicon Image 3132 designation in the description of the card. Almost  
every manufacturer of 3132 cards is using the SiI "reference design",  
so they all work alike, although some cost $40 and some cost $90.

If you have a PCI-E card, and it is in BASE mode, then your desktop  
has the same capabilities as described, above.
