Does the Marvel 9128 controller support TRIM?

post #1 of 8
Thread Starter 
All right pretty simple question.

I was planning on buying a SATA III drive but I wanted to know if the Marvel 9128 controller would send the TRIM command to my SSD.

I've tried googling around but I've seen answers that say yes and no.

I've got the Marvel 9128 on my previous mainboard (P7H57D-V EVO). It does not pass the TRIM command to drives.

Anyway, from my experience TRIM is overrated, if your SSD provides a good garbage collection, the speed doesnt drop.
The Crucial C300 in this rig shows the same performance since its installed (more than 1 year till now) Take a look at the Crucial forums for more explanation about the garbage collection feature.

And the Marvell controller is pretty fast, here is a screen with C300 on Marvell

Using Marvell controller is just stupid. You get faster speeds even on native Intel SATA II controller and also TRIM support in addition. So why bother messing with buggy Marvell driver and castrated Marvell controller?

Just an example of my C300 64GB bench on Intel SATA II controller:



P.S. Sequential speeds don't matter for OS drive. It's a fact. And additional 60MB of read speed is just pathetic compared to a boost in 4k speeds on Intel controller.

I believe it does not.

I dont know about any buggy marvell drivers, and i never had any problems.

As i said, its pretty fast and to me it sounds much more stupid to run a ssd on a SATA II controller if there is a 6GB/s controller avail. Anyway, be happy with your setting XSCounter.

Well, I guess there is no point arguing if you don't see the obvious facts simply by comparing two screenshots. We have identical SSDs but I use native Intel SATA II port and you use PCI Marvell SATA III controller. I get much better results using SATA II controller than you using Marvell SATA III controller. Conclusion is that using Marvell is pointless as it gives only disadvantage in terms of worse 4k speeds and lack of TRIM support (4k speeds are most important!).

I've got Marvell SATA III controller on my board as well and did enough testing and independent research to be certain of my words.

I just want to make sure that people who read this thread don't do the wrong thing by using Marvell port. I know you feel like you need to justify the money spent on this additional feature on the motherboard. But it was simply marketing and these Marvell controllers are completely useless. All the tests and reviews on the net confirm it.

Another Intel > Marvell user here. At least on my P7P55D-E Pro.
