Welcome to Tom's Forum!
Possible then yes, advised on the Marvell then no. The Marvell® 9128 is a PCIe x1 v 2.0 controller or max is 500MB/s / 2 = 250MB/s (real world less) plus latency for the SSD's in RAID 1 on the Marvell.
Instead if you're not interested in adding a RAID Card then keep everything on the Intel SATA ports:
* Boot Intel SATA2 (300 MB/s) ; the OS and Applications are all about 4K Random R/W with lowest latency. Marvell are often data only on most MOBO's i.e. not bootable, but on the ASUS X79's are bootable so if you boot off the Marvell then ideally use (1) one SSD and you'll get 370MB/s~390MB/s but there will be some added latency. In other words you'll be splitting hairs in real world performance. Also, as I recall on many of the ASUS X79's you'll lose your PCIe x1 slot i.e. Marvell 'on' = PCIe x1 'off'; check your manual.
* RAID 0 Intel SATA3 (600MB/s each or up to 1200MB/s) ; RAID 0 I would assume you want the fastest possible R/W at a variety of file sizes and que depths.
* RAID 1 Intel SATA2 (300 MB/s) ; the Intel still is faster and offers the lowest latency.
