Saw the velocity solo x2 could support boot camp/Windows unlike the Sonnet Tempo SSD (http://forums.macrumors.com/showthread.php?t=1556095&page=2). This is a non RAID setup on a Samsung 840 pro; pretty much just to get my boot SSD on sata 3 since it is cheap $70. Solo x2 works great except 2 main trade-offs. System fan now hums at an annoying pitch, no longer a dead silent machine. Only goes away when the x2 is removed from the machine, doesn't matter if the x2 has the SSD physically installed or not. Tried 2 cards, same result and does not go away after PRAM/SMC resets. Second, PRAM resets will make the machine "lose" the startup volume forcing you to navigate the menus blindly if you are using a non Apple OEM graphics card. 1st picture in each is the before. 2nd blackmagic is the Sonnet, 3rd blackmagic is the x2. The last 2 are the Windows-based tests from the Samsung Magician software.
