this, I believe that a 4x cable will not give you any benefit over a

SATA drives are single-ported, while some SAS drives are dual-ported.
However, there are no quad-port SAS drives so why the 4x cable?

To provide a separate SATA channel to each drive? With a 1x cable
wouldn't I/O requests for all four drives have to share the same link.

A well designed controller should be able to do exactly that. Each
port should
be able to concurrently talk to a separate disk drive. I have no idea
if the LSI card
mentioned above does that though. Maybe someone else knows.
