6. Serial ATA Supported
This motherboard comes with integrated Serial ATA controller in chip, aiming to provide you
an even faster transfer rate of 150 Mbytes/second. For AX4SG-L model, it also provides
RAID 0 when you use Serial ATA hard disks. The traditional parallel ATA specification has
defined the standard storage interface for PCs with its original speed of just 3 Mbytes/second
since the protocol was introduced in the 1980s. And the latest generation of the interface,
Ultra ATA-133, has been developed further with a burst data transfer rate of 133
Mbytes/second. Please be noted that Hot-Plug in is not allowed.
7. Connecting Serial ATA Disk
To connect a Serial ATA disk, you have to have a 7-pin serial ATA cable. Connect two ends
of the serial ATA cable to the serial ATA header on the motherboard and the disk. Like every
other traditional disk, you also have to connect a power cable. Please be noted that it is a
jumper free implement; you don’t need to set jumpers to define a master or slave disk.
When serial ATA hard disks are installed on serial ATA ports, the one connected on Port
0(SATA 1) will be set as the first boot device automatically.
