Hmmm yeah ok, well, it is still interesting to see what drivers/software you're using (original Apple or not) that makes this setup work! That would be very nice indeed, although I cannot find any other source that has a working config like yours :/
Ok, also interesting, no performance hit? I am not sure how Macdrive works but I guess it replaces the Apple HFS driver?
I only had the Boot Camp driver. What I do know is that Apple's only official position is that you can't install Windows on a soft RAID, not that you can't access a soft RAID through File Explorer. But then they also think systems before 2012 can't run Windows 10.
I did install the demo version of Mac Drive to test write speeds and it was slower than native writes.
Before writing people off, consider this people's experiences with configuring their cMP systems.
- some can install Windows in EFI mode without hassle, some can't.
- some can install a SM951 in slot 2 and it runs at half speed. Macvidcards was saddened to find his working at quarter speed.
- I installed a USB 3.1 card and it negotiated the correct x2 lane link. 666sheep has the same card in the same slot and it can only negotiate a X1 link.
- I could access software RAID 0 and 5 from Windows. You couldn't access a RAID 10.
- some guys can run a Radeon 7970 using a 6pin and mini 6 pin to 8 pin adapter right off the motherboard. Some can't use a high power card, their systems are forced to shut down.
There are many such examples of random behaviour in cMP, almost all related to either Windows or the use of PC hardware.
