Windows 7: What is the difference between Bus and Location on SATA ports

10 Aug 2016   #1

What is the difference between Bus and Location on SATA ports

I was looking at device manager to see if i have my hard drives hooked up right. I wanted my Kingston SSD to be on SATA port 0 which is the built in dock on my case. I checked and the SATA cable is going from SATA port 0 to my dock on my case. But in device manager it says bus 1. My other 2 hard drives that are the same make and model in device manager it says location 0 and location 1. In my BIOS i did set i think it was SATA ports 0 to 4 to AHCI and SATA port 5 and 6 to IDE (no other choice for the latter ports).

So what is the difference between the two, bus and location? Which one is faster to get 6 GB/s on my SSD and my one Seagate Firecuda SSHD on the SATA ports. My motherboard does support 6GB/s.
