I picked up an external PMP/Cage/RR6622 combo that claims to be Sata III. From the BIOS, the card implies it does indeed see the SATA III drives Pic of the BIOS here http://tancsa.com/rr.jpg ahci0: <HighPoint RocketRAID 622 AHCI SATA controller> port 0x4090-0x4097,0x4080-0x4083,0x4070-0x4077,0x4060-0x4063,0x4050-0x405f mem 0xc2430000-0xc24307ff irq 16 at device 0.0 on pci1 ahci0: AHCI v1.00 with 2 6Gbps ports, Port Multiplier supported with FBS ahcich0: <AHCI channel> at channel 0 on ahci0 ahcich1: <AHCI channel> at channel 1 on ahci0 However, performance is abysmal and worse than using a regular sii based SATA II card.
