Many of us moved to the R3E from R2E, why ............. because it has Sata 3 6gb/s and USB 3, those are the main changes, well guess what, the marvell 9128 is almost useless if you are using SSds in raid, ask any one, as for usb 3 yes it works, its quick but for what purpose, oh my back up drive is really quick now........whoope friggin do !
You best run your vertex 2s on the intel for now.
I dont think the firmware we need will ever be released.
