I have read that some motherboards treat all SATA3 drives independently, so that each drive can hit 6Gb/s theoretical throughput, while other motherboards put things on the same Bus, so they share the bandwidth. I assume also that they may be grouped, such as device 0-3 are one bus, and 4-5 another, for example.
I am hoping to know for certain which boards support independent and which boards don't. For the application I am writing, this feature may impact performance, so I want to test. Specifically, I what I am worried about is if I have three drives, will they trip up on each other doing seeks, or can they run smoothly in parallel? I assume independent buses will guarantee this does not happen, but that is an assumption, which is dangerous. Maybe I really want to look up a different feature.
It is hard to keep up with terminology for minor features such as these.
I don't know what the buzzword is to search in order to read up. Can anyone give me some guidance?
