I recently purchased an Acer desktop PC. It came equipped with a Seagate 1TB drive rated at 6Gbps data transfer speed and a 64MB cache. I added a second identical drive using the front loading "Easy Swap Expansion Bay" which is mounted in the spare 5.25" bay. I subsequently migrated to a RAID 1 configuraiton using Intel Rapid Storage Technology (IRST) preloaded on the PC.
When I look at the detailed IRST System Status report, I see that my OEM drive is on SATA Port 0 and it's running at 6Gbps transfer rate. My new drive is on SATA Port 2, but it's only running at 3Gbps even though it's rated for 6Gbps. Other reports indicate the RAID configuration is operating normally.
So why is the new drive limited to only 3Gbps? Do the various SATA ports have different speed settings? The Easy Swap Bay sits where a second optical drive whould be installed and probably connected to Port 2. Is the Port 2 speed set lower in the BIOS assuming it will connected to an optical drive? Is it likely that the unused SATA Port 1 is configured for 6Gbps because it would normally be connected to an additional drive mounted in the spare 3.5" bay? Finally, is there a way to set the port speed for Port 2 to 6Gbps, or would I have to relocate the new drive to the spare 3.5" internal bay and use the cable intended for it?
Lots of questions in my mine. I sure would appreciate it if someone could help me get my new drive to operate at 6Gbps speed.
