Not all that surprising, since the 9500-series use PATA-133 chipsets with 
SATA-PATA bridges, and the 9550+ uses a native 3G SATA chipset.  Even 
though the 9500s are listed as 1.5G SATA parts, you'll never get better 
than ATA-133 speeds out of them.

We didn't realise that when we ordered our first pair of Escalade 9500S 
4-port cards.  Thankfully, just after they arrived and before we put in 
the mass-order, the 9550SX was released and we've standardised on them.
