Fusion drive + Bootcamp on mid 2012 MacBook Pro 15"

Dear all,

I am in a sort of delimma now, as I am trying to set up a Fusion Drive with a Bootcamp partition on my 2012 MacBook Pro 15" with a Hitachi 750G HDD and a Crucial Micron M4 256G SSD. Here are the challenges I read up from other threads or personally encountered:

1) The Bootcamp partition would only boot when the drive is in the disk0 partition, meaninig I it will boot when the HDD is in the original HDD slot or when it's in the Optibay with the SSD disconnected. It, however, won't boot when it is in the Optibay with the SSD in the original HDD slot connected.

2) The SATA connector in the Optibay is rated for 6G data rate, but there has been reports of spotty performances when it tries to negotaite the 6G data rate of SATA-III devices.

So as of now I am at a delimma of either to put the SSD in the HDD slot and forefeit the dual-boot setup, or to put the SSD in optibay and put up with the occasional beachball. Has anyone been able work out something aronud this problem?

p.s. I read somewhere that the poor performance of SSD in Optibay had to do with inteference in the cable, so I had the birlliant idea of shielding the optibay enclosure and the cable with aluminum foil - so far it does not seem to have an effect.
