Crucial m4 128GB: Intel ICH10R vs Marvell 9128 (SATA 3)

Pretty simple. Intel is preferred over Marvell.

Johhny's right but you could try some PCI-E overclock if you wanted to use the Marvell chip. It responds well since the Marvell runs off the PCI-E bus. Usually only make it as far as your gfx card will allow though.

Thanks guys. I'm going to use the Intel port. The Marvell port is known for being unreliable and no one is sure if it supports TRIM. My guess is that it does not, since Marvell has made no comment about it. I will have to wait until I get a motherboard with native SATA3 support to get the most out of this drive.

Good point!! Along with that, the Marvell controller is SATA III versus the Intel SATA II controller. This will give you a little better performance on it's own. If the motherboard was an Intel SATA III controller, I would say without a doubt the Intel.
