The single port version is akin to a dedicated RAID card with 4 Sandforce-1200 SSDs. The main benefit of this connection is the 4 port version in a single PCI Express x16 2.0 slot. Anandtech predicts it might reach 2.5GB/s Hopefully, if this takes off OEMs can drop the internal SATA RAID going on inside the device for even further gains. EDIT: also very encouraging is the internal garbage collection that goes on when the disk is idle. Trim does not work on RAID and it is great to see performance can still be regained after prolonged use.
