The motherboard has two Marvell 88SE9172 chips:
1. 2 x SATA 6Gb/s connectors (GSATA3_6, GSATA3_7) supporting up to 2 SATA 6Gb/s devices
2. 2 x eSATA 6Gb/s connectors on the back panel supporting up to 2 SATA 6Gb/s devices
3. Support for RAID 0 and RAID 1
This is not a GSATA2 chip which is actually a renamed JMicron HMB363 chip. The RAID would work if you were using the same hardware, but you aren't so there is no reason to think it would work.
