Which SATA ports should I use?

post #1 of 8
Thread Starter 
On my latest build I am using the ASUS P8Z77-V mobo, which comes equipped with two onboard Intel Z77 SATA III (6Gb) and four SATA II (3Gb) ports. The mobo also includes two ASMEDIA SATA III (6Gb) ports.

I am using an Intel SSD drive as my primary boot and system drive. I also have an internal WD Caviar Black 1TB HDD (SATA III), a Bluray burner (ATAPI) and an eSATA case port, which I use for an external storage device (1.5Gb).

I have connected my SSD on the Intel port-0 SATA III (6Gb). My Bluray is on the Intel SATA II port since the ASMEDIA ports don't support ATAPI devices. But I have some different options for my WD internal HDD, and my eSATA external connections.

My questions:
1- Despite the WD Caviar Black being rated as SATA III, we all know HDD drives don't come close to that throughput, so does it matter if I wire it to a 6Gb SATA III or a 3 Gb SATA II port? Will there be any performance or compatibility issues if I used a 3Gb SATA II port?

2- If I do connect it to a SATA III port, does it make any difference if I connect to the Intel or the ASMEDIA port? What is the difference between them?

3- Does it matter where I connect the eSATA external port? I'm not sure if all ports support eSATA, or there are compatibility issues between the 3 different ports.


I was planning on getting another SSD at some point down the road to setup a RAID set, so I was going to leave the second Intel SATA III port open for that.

I don't know how the internal I/O bus is configured and whether there would be potential advantages to spreading the load across multiple ports to avoid bottlenecking when there are multiple devices in use.

Please discuss or share any useful links that might help sway this decision.


Thanks.

there should be instructions in your motherboards box supplying the above information

if you don't have, look up the chart for your model online

I have read through the docs that came with the mobo, but there are very few details, and it certainly does not answer my questions. I have swapped the connections around several times and everything seems to work fine no matter which way I connect them. I don't think there are any compatibility issues, but I wonder if there would be any performance gains if I configure them a certain way.

The eSATA devices are limited to 1.5Gb so I don't see any problem putting that on one of the SATA II ports. The WD HDD has a SATA III controller, but I'm thinking this is just a marketing gimmick, and probably would not matter if I use a SATA 2 or 3 port. It would be good to get confirmation of that. I would also like to know what the differences are between the Intel and Asmedia SATA III ports, if any. The docs state I can setup Raid on either one, but can't mix.

I'm really looking for the most optimal config.

It doesn't really matter. I would put the SSD on the Intel 6GB port, and then you can either leave the second port open or put the WD drive on it. You won't see a performance difference either way, but you can always move it later without a problem if you put it on the 6GB port and then get another SSD. I would put the eSATA connectors on the Intel 3GB ports (and set them for hot-swap in the BIOS).

Leave the ASMedia ports as your last resort.

What does that do... What happens if you don't do this?

I think Hotswap means you can remove the drive connected to that port when the computer is on(which you probably want to do with a eSATA device).

Exactly. Some boards don't have it enabled by default, so check and see.

The hotswap point is a good one. You definitely want it if you are using an eSATA device on that port so you don't need to restart or open device manager and manually scan for new hardware every time you plug in a drive.

There is highly unlikely to be any significant difference between the two with a HDD.

SSDs will certainly perform better on the Intel ports. In some cases, the Intel SATA II ports may be faster than the ASmedia SATA III ports. Most simple PCI-E SATA III controllers perform quite poorly relative to native Intel controllers.

Not unless you intend to connect a fast SSD to it.
