I currently have two SATA3 drives on the same controller. I have noticed that when I transfer from one of the drives to my server, I see 90-110 megabytes per second; this is done via a gigabit Ethernet. However, if I am transferring between the two drives, I only see rates half that. I would’ve thought that with SATA3 I could at least see about 200 MB/s (100 up, 100 down) because theoretically SATA3 has a max of 6 gigabit per second. Am I misunderstanding how the controllers work for this?
