agulerer Posted September 2, 2011 Share Posted September 2, 2011 I am using GIGABYTE 990FXA-UD7 board and on it there is Marvell 88SE9172 Sata3 controller and SB950 controllers for Sata3. I want to setup raid 0. Which one should I prefer? Marvell new 88E9172 sata 3 controller or sb950 raid controller. I will use Corsair Force 3 Gt SSD for raid 0. On some site I see new Marvell 88SE9172 controller is pretty good but I need to learn if someone used it and experiences? Also some intel boards uses this new marvell chip.

scorpionri Posted September 2, 2011 Share Posted September 2, 2011 The general opinion seems to be that you should stay away from the Marvel SATA controllers and just use your chipset controlled ports ( in your case the SB950 ones ). Link to comment Share on other sites More sharing options...
agulerer Posted September 2, 2011 Author Share Posted September 2, 2011 Why do you think I should stay away Marvel Sata controllers? These are new sata chips of Marvel so maybe it will be better. I just want to learn if anyone used it or not? Link to comment Share on other sites More sharing options...
scorpionri Posted September 2, 2011 Share Posted September 2, 2011 There are a few reasons to avoid the Marvell controllers - they usually use a 1x PCIe (the exception seems to be 9182, which uses 2x ) - they don't seem to support TRIM ( driver issue, not actually hardware issue ) - they usually provide worse small writes performance than the Intel controller ( be it SATA II or III ); on the plus side they do get better reads than the Intel SATA II; again the 9182 seems to perform better - official Corsair reps mentioned that they'd recommend staying away from Marvell because they also have stability issues Link to comment Share on other sites More sharing options...

scorpionri Posted September 2, 2011 Share Posted September 2, 2011 AFAIK they still don't support it. I don't think it should be a HW problem, but I have no idea why they didn't implement it. Link to comment Share on other sites More sharing options...
