I'm planning to put 2 Samsung 830 128GB SSDs into RAID 0 and I want to have half of the RAID for Mac (this is a Hackintosh build) and the other half for Windows so I can get the best performance possible. Is this possible?
yep you can, probably best to use a 3rd party partition manager for it though.
wel it could mabye possible, but it would not that easy as you think it is. because you working with 2 totaly diffrent operating systems. in a software raid... i think that could get a pain in the ass. but you can allways try it, using EASUES partition Master pro. but it could be possible that windows 7 will destroy your multiboot. so you need to be sure that mac os supports that.
I would personaly use 1 SSD for mac the other for windows.
