Windows 7: Intel ICH10R vs Marvell 9128 raid 0 performance

Windows 7 Ultimate x64
Intel ICH10R vs Marvell 9128 raid 0 performance


I have a Raid 0 configuration with two Intel SSD Sata3 256 GB drives (6Gb/s), using the SATA connectors on my mobo (Asus Rampage III Extreme). Each of these drives reach up to 450MB/s for separate, and in Raid0 they should reach near 900MB/s. Example, using same drives:

The mobo has 2xSATA3 connectors (Marvell 9128 controller) and 6xSATA2 connectors (Intel ICH10R controller). These are the performances I get using each of them:

Supossedly I should be getting something near to 900MB/s 2, quite below the bus limit (2x6Gb/s = 1200MB/s) using the SATA3 connectors, but I only get 316MB/s.
I have read that Marvell 9128 performs well in single-drive SATA3 configurations, but has issues with SATA3 raid configurations.

I'm thinking now on getting the Raid back to ICH10R, or purchasing a decent SATA3 Raid controller.

Can anyone bring some light / advices into the matter?

Thanks a lot in advance!
