From my past experiences with Magma (we used to import and distribute them in Japan), I decided to give a try on Magma ExpressBox2 with RED Rocket™.
I'm hoping this will provide some support with MBP to use with RED Rocket™ and Calidigit RAID card that provides internal and external RAID drive configuration (although I would have to be careful with the bandwidth to reserve for RR operation) AND, more robust support with Mac Pro to provide full speed support on RR and extra PCIe bus for another card like eSATA card (since all of my busses are used up). I'm hoping that the second slot won't take so much bandwidth, so I can operate the RR fully.
And I'm hoping this will work with Rocket Fuel on HP Dream Color laptop, too.
I'll provide the report on this when I receive them.
