3. Serial ATA connectors (7-pin SATA1, SATA2, SATA3, SATA4)
Supported by the NVIDIA ® nForce4™ chipset, these connectors are for
the Serial ATA signal cables for Serial ATA hard disk drives that allows
up to 3Gb/s of data transfer rate.
If you installed Serial ATA hard disk drives, you can create a RAID 0,
RAID 1, RAID 1+0, RAID 5, or JBOD configuration.
Important notes on Serial ATA
The actual data transfer rate depends on the speed of Serial ATA hard
disks installed.
