My Corsair 120gb Force 3 perfomance.

Recommended Posts

Hello. I have recently bought my 120gb Force 3 SSD and I was wondering if my SSD is working as it should be? Is it working slower than it's suppose to?

 

I downloaded some of the benchmark programs that show you SSD figures.

 

If i'm not mistaken I am sure I plugged my SSD into my 6gb/s Sata 3 connection on the motherboard but not sure how to check if it's actually using it. I'm also using my SSD with AHCI as far as I know.

 

Here are some of the screenshots I took of the benchmarks. I couldn't do a PCMark Vantage test because I only had a trial account.

Your motherboard Gigabyte GA-X58A-UD3R has two Sata3 ports that are handled by Marvell drivers. The Marvell drivers right now are bad at handling Sata3 SSDs and severely limit their performance.

 

Here's a picture of your motherboard (Gigabyte GA-X58A-UD3R) highlighting the two Marvell sata3 ports:

Here's a picture of my motherboard (Gigabyte GA-Z68X-UD3H-B3) highlighting the Marvell sata3 ports in red but also highlighting two Intel sata3 ports in green:

Here is an ATTO benchmark of my two 120GB Force 3 in raid0 on the Marvell sata3 ports:

So basically the bottom line is Marvell Sata3 ports are bad for Sata3 SSD performance, severely bottleknocking the performance. Whereas the Intel Sata3 ports are great for Sata3 SSD performance.

I am glad I saw this...I have the Asus X58 Sabertooth motherboard and am using the Marvell Sata 6Gb connector with my Corsair Force3 120. I am totally new to SSD hardware (and to benchmarking drives come to think of it). This is the result I get with my current set up. I have not tweaked anything on my system yet as I am still reading up on stuff.

If I understand Turob correctly we should be aiming to get as high a transfer rate as possible, is that correct? If the Marvell connection is bottlenecking the system is this just a temporary setback whilst they sort the drivers and should I just use the regular 3Gb Sata3 ports on my system board?

Is there anyway I can stop those 6gb/s sata 3 ports from using the marvel 9128 or do I have to use the other sata 3 ports which are 3gb/s to get better perfomance?

 

I heard that 3gb/s ports doesn't give SSD's full perfomance, right? Or did I mix that up with Sata2 and Sata3 connections?

 

Here's a picture I found on the overclock3D website

At the moment as you have pointed out I have connected my SSD to the 3_7 and 3_6, Sata3 6gb/s ports.

 

From my manual that is the only sata port using Marvel 9128 chip. The other ports 2_0 to 2_5 are Sata2 3gb/s from the south bridge of my motherboard. Gsata 2_8 to 2_9 are the gigabyte sata2 chip which is still 3gb/s.

 

Which ones should I use?

 

 

Not sure what I did but I ran some tests again and these atto figures are so different from my 1st test. (Not swapped the sata cables yet)

I don't know if your SSDs will perform better on the Sata 3 Marvell ports or better on the Sata 2 Intel ports. That's a pretty good question. I'd be really interested to see what your ATTO benchmarks would show as a comparison.

Sunniie, No, I don't think you can have your Marvell Sata3 ports stop using Marvell because I think it's an actual chip that it runs off of. You can try updating the drivers for the Marvell chip to a more recent version which will probably help, but you're stuck. You can't turn a Marvell sata3 port into an intel sata 3 port, etc.

Turob...or indeed anybody?
