supports PCI-E 3.0 x4 (32 Gb/s) SSD cards in the 2280 and 22110 form factors.
I-SATA 3.0 and S-SATA 3.0 Ports
The X11DDW-NT has eight I-SATA 3.0 ports (I-SATA0~3, I-SATA4~7) and six S-SATA ports
(S-SATA0~3, S-SATA4, S-SATA5). These SATA ports are supported by the Intel C620 chipset.
S-SATA4/S-SATA5 can be used with Supermicro SuperDOMs which are yellow SATA DOM
connectors with power pins built in, and do not require external power cables. Supermicro
SuperDOMs are backward-compatible with regular SATA HDDs or SATA DOMs that need
external power cables.
