ASUS Z87-Deluxe/SATA-Express Detailed

ASUS released a prototype of the first desktop PC motherboard with SATA-Express support, the Z87-Deluxe/SATA-Express. A variant of ASUS' flagship socket LGA1150 motherboard from its mainline Z87 series, the Z87-Deluxe, the board features two SATA-Express ports. SATA-Express sees a fusion between two of the most successful serial I/O interfaces, SATA and PCI-Express. It's essentially ATA over PCI-Express 2.0 x2, which offers a raw bandwidth of 8 Gbps per direction, 16 Gbps total. The SATA-Express port is structured similar to the classic SATA port, with PCI-Express lanes running over two 7-pin SATA connectors, and an additional block of 4 pins that make up the 18 pins required by 2-lane PCI-Express. A SATA-Express connector is thus unified, and legacy SATA devices should still be able to run off one of the two 7-in SATA connectors in a SATA-Express block.
