No RAID 0, do not know enough about it to experiment. and if im honest any risk is still risk. wouldn't go for it, the reason for is one for OS and programs 1 for games I play the most.
I suspected that being the case. :)
Still, I would have gone fore a cheaper solution: a single but larger capacity SSD partitioned for OS volume and Games volume.
To be honest mate these SSD's where actually a steal. cheap considering what is out there.
That's fine, it's a great build. No argument about that. All I said, that I personally would have gone for a single drive instead.
