I-SATA 3.0 and S-SATA 3.0 Ports
The X11DPG-QT has eight I-SATA 3.0 ports (I-SATA0~3, I-SATA4~7) which are supported by
the Intel® C621 chipset. In addition, it also has two S-SATA 3.0 ports (S-SATA4/ S-SATA5)
that are supported by the Intel® SCU. S-SATA4/5 can be used with Leadtek SuperDOMs
which are yellow SATA DOM connectors with power pins built in, and do not require external
power cables. Leadtek SuperDOMs are backward-compatible with regular SATA HDDs or
SATA DOMs that need external power cables. All these SATA ports provide serial-link signal
connections, which are faster than the connections of Parallel ATA.
