Serial Ata Interfaces - Intel BLKDG45FC Technical Product Specification

Intel Desktop Board DG45FC Technical Product Specification
1.6.4

Serial ATA Interfaces

The board provides four Serial ATA (SATA) connectors, which support one device per
connector. The board also provides one red-colored external Serial ATA (eSATA)
connector on the back panel.
1.6.4.1 Serial ATA Support
The board's Serial ATA controller offers five independent Serial ATA ports with a
theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed
on each port for a maximum of five Serial ATA devices. A point-to-point interface is
used for host to device connections, unlike Parallel ATA IDE which supports a
master/slave configuration and two devices per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the
operating system. The Serial ATA controller can operate in both legacy and native
modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14
and 15). In Native mode, standard PCI Conventional bus resource steering is used.
Native mode is the preferred mode for configurations using the Windows* XP and
Windows Vista operating systems.
NOTE
Many Serial ATA drives use new low-voltage power connectors and require adapters or
power supplies equipped with low-voltage power connectors.

The board supports the following RAID (Redundant Array of Independent Drives)
levels:
• RAID 0 - data striping
• RAID 1 - data mirroring
• RAID 0+1 (or RAID 10) - data striping and mirroring
• RAID 5 - distributed parity
