Intel 3Gb/s vs Marvell 6Gb/s

post #1 of 19
Thread Starter 
I hate this.

R3E has 2 Marvell 6Gb/s ports and multiple Intel 3Gb/s ports. I remember doing a test back in the day and coming out with the Crucial C300 256GB performing slightly better on the Marvell 6Gb/s ports.

That being said, I now have a total of 4 SSDs. 2 of them are 64GB Crucial M4s and 2 of them are 256GB Crucial C300s. I was planning on using the 64GB SSDs as my OS drives (one for W7, one for Linux).

Should I just use them all on the Intel ports and disable the Marvell ports or should I purchase a SATA controller and use that? I think I read somewhere that a controller would cause slight lag and the Intel controller goes for ~$400.

Why not try both and do a benchmark? Then decide.

Also, if you have that much change to spare on SSDs then why not get a mobo with more 6Gb/s ports? Even mine has 4 of them (but 2 are Marvell)

I wish I had that much change. Haha. If I had that much dough to blow I would have just purchased the Intel SATA controller for $400 and tested it out then.

The reason I don't buy another motherboard is because I don't know if the SATA controller would be better or worse than the ports already on there. Like I said, I thought I saw somewhere that the controller adds a lag.

The other/main reason I don't buy another motherboard is because I have an LGA 1366 processor. You can't find many modern motherboards in the X58 chipset anymore. The only "performance" ones I know of are the EVGA X58, the R3E and the GIGABYTE G1 but they're all relatively the same, right?

I have no idea about motherboards for 1366.

I know that the Marvell controllers are worse than the Intel controllers. I would surely use Intel > Marvell if both were 6Gb/s.

But I would hope that the Marvell 6Gb/s ports are better than the Intel 3Gb/s ports. In which case I would use the Marvell.

I would not use the Marvell ports, the 9128 controller is complete garbage imo. From personal experience even, i see better performance limiting my SSD to SATA 2 Intel over the 9128 SATA 3, and also do not get the BSOD i was getting while using the Marvell controller.

Edit: My SSD is rated at 555 MB/s sequential read — 495 MB/s sequential write, 80K IOPS random 4k write

Yup. I saw a couple benchmarks that put the Intel 3Gb/s over the Marvell 6Gb/s. I know that they are garbage, but from my single benchmark the C300 256GB prevailed on the Marvell controller...barely, so I was using them.

With 4 SSDs now, I can either stick 2 on the Marvell ports and 2 on the Intel, or just be consistent and stick them all on Intel, which might be my choice here.

Any comments on the PCIe SATA controller though?

Marvel = crap

Intel = good

Fill all the Intel ports up with the SSDs

Are you trying to RAID your drives or just need a controller that can run them in parallel?

I was not planning on putting my SSDs into RAID. I won't get into that debate here because I don't know for sure which is better to do, but I know that the Intel SATA controller, if I recall correctly, had the capability to RAID if I ever chose to do so, and it also had I believe a total of 8 Intel 6Gb/s ports.

Would this be a better alternative if I can find an extra PCIe slot for it?

I'd just use the intel ports...Ich9-10 is pretty good IMO.Well better than AMD anyway :lachen.gif:
Nvidia RAID is pretty good
