Connectors
Floppy Disk Connector: FDC
These mainboards provide a standard floppy disk connector (FDC) that supports 360K, 720K, 1.2M,
1.44M and 2.88M floppy diskette drives. This connector supports the floppy drive ribbon cables provided
in the packaging.
Hard Disk Connectors: IDE1/ RAID IDE1-2/ SATA1-4
These mainboards provide a standard IDE connector that supports PIO Mode 0~4, Bus Master, Ultra
ATA 66/100. These boards also contain 2 RAID IDE connectors that supports Ultra ATA 133
transmission rates and RAID 0/1/0+1 and JBOD modes. 4 Serial ATA connectors are also available and
can provide 150 MB/s transmission rates.
IDE1 (Primary IDE Connector)
You can connect 2 IDE devices to the IDE1 connector using a single ribbon cable with 3 connectors (2
for the drives and one to connect to the board). If you are connecting 1 drive, you should configure it as
the Master device. If you are connecting a second drive, you must configure it as the Slave device (see
your hard drive manual for master/slave configuration specifics). If you have an IDE CD-ROM drive, you
just can attach it to this connector.
RAID IDE1/ RAID IDE2(RAID IDEconnector)
These connectors are capable of sophisticated disk management using RAID 0/1/0+1 and JBOD modes
（for more details about RAID configuration, please refer to the ITE RAID Controller manual）. As
with the IDE1 connector, you can connect 2 drives to this connector. If you are attaching a second drive,
the first drive must be configured as the Master with the second drive being the Slave (see hard drive
manual for master/slave configuration specifics). This connector can be only used with hard disk
devices.
RAID 0 (disk striping) Striping is a performance-oriented, non-redundant disk storage technology. With
RAID striping, multiple disks are used to form a larger virtual disk. Data is then striped or mapped across
all the physical disks. In this way disk drives can perform multiple I/O operations in parallel, enhancing
performance.
RAID 1 (disk mirroring) With Disk Mirroring there is a redundant disk that mirrors the main disk. Data that
is written to the main disk is also written to the redundant disk. This redundancy provides fault tolerant
protection from a single disk failure. If a read/write failure occurs on one drive, the system can still read
and write data using the other drive.
RAID 0+1 This mode combines both the performance benefits of RAID 0 with the fault tolerance of RAID
1
JBOD (Just a Bunch Of Disks) This mode provides you with a way to combine many hard drives to
create a larger drive. The JBOD drive will operate with the same functionality as a standard hard drive.
SATA1-4 (Serial ATA connector)
These SATA connectors (SATA1 – SATA4) support Serial ATA 150. Each SATA connector can only
support one serial ATA device. Note: With most storage devices, there is a power cable that you need
attach to a power source (power supply).
