SAS Raid controller drive channels

[invisik]

Hi!

In regards to servers with the P440ar RAID controller (like DL380 Gen9), this RAID controller says it has dual channels.  It seems to be connected to the SFF 8-bay drive cage with drive slows 0-3 on one cable and 4-7 on another cable. 

Is there any advantage to putting some drives on one channel and some on the other from the same array?  Like if a I have a RAID 1, I could put a drive in bay 0 and bay 4 (versus putting them in bay 0 and bay 1).  Kinda like duplexing, but on a single controller.....

Thanks for any experiences with this.
