I would like to applie to PC by SAS SSD using a RAID card.
However, I am concerned about the secondary port(s8~s14 pin out) of SAS SSD.

And I noticed that can used for the 8643 connector of the raid card`s by 1: 4 (single port) and 1: 2 (dual port) cable.
I tried the applied with both cables,
The SSD was recognized as normal and no difference in speed or function could be found.

So I ask.
What is the interface capability of the SAS secondary port (s8 to s14, rx +/- 1, tx +/- 1) and for what reason is it used?
I seek advice from experts.
