1.6  Discrete Serial ATA Interface (Optional) 
1.6.1  Serial ATA Controller 
As a manufacturing option, the board provides a Marvell 88SE6145 Serial ATA (SATA) 
controller and four connectors (that support one device per connector) for SATA 
devices.  These connectors are in addition to the four SATA connectors of the 
ICH7-R/ICH7-DH SATA interface.   
The Marvell 88SE6145 controller uses the PCI bus for data transfer with a theoretical 
maximum transfer rate of 3 Gbits/sec per port.  The discrete SATA interface supports 
the following RAID levels: 
•  RAID 0 
•  RAID 1 
 
NOTE 
The Marvell 88SE6145 controller supports single drive non-RAID configurations as well 
as RAID configurations.

SATA drive.
