Serial ATA Connectors
These next generation connectors support the thin Serial ATA cables for primary
internal storage devices. The current Serial ATA interface allows up to
3.0Gbit/s data transfer rate, faster than the standard parallel ATA with 133 MB/s
(Ultra DMA).
USB 2.0 Connectors
The mainboard provides two front USB pin headers, allowing up to 3 or 4
additional USB2.0 ports up to maximum throughput of 480 Mbps. Connect the
2-port USB cables into these pin headers. These ports can be used to connect
high-speed USB interface peripherals.
