4. Hard disk activity LED connector (4-pin HDLED1)

This LED connector is for the storage add-on card cable connected to

the SATA or SAS add-on card. The read or write activities of any device

connected to the SATA or SAS add-on card causes the front panel LED to

light up.

3. SAS connectors (7-pin PSAS1–8 [Blue])

Supported by the ASUS

PIKE Card, these connectors are for the SAS signal

cables for SAS hard disk drives that allows up to 6Gb/s of data transfer rate.
If you installed SAS hard disk drives, you can create a RAID 0, RAID 1, RAID

10, or RAID 5 configuration.

The actual data transfer rate depends on the speed of SAS hard disks installed.
