SATA Backplane Question

[sniffsunderclouds]

I'm researching my current NAS build and I'm considering installing a 3 or 4 bay SATA backplane system.

Can anyone tell my why the IcyBox system has primary and secondary SATA connectors on the rear panel?

Also if anyone has used this system can you give any feedback on it?

Thanks

Those ICYBOX folks have some goofy spec sheets. I believe the dual channel support is for SAS disks since SAS is full duplex while SATA is half duplex.
