I'd be curious if there were any differences between Disk 1 and Disk 2 when booting. The only (significant) difference (IMO) is that Disk 2 is bootable, while Disk 1 isn't. That'd explain the BSOD after the attempt at logon. It should also (I presume) then BSOD when attempting to go into Safe Mode (with Disk 2).
Basically, the more different things that you try, the more likely you are to notice a pattern (such as Disk 1 and Disk 2 at least try to boot, while the SSD gives you freezes. And, if the SSD freezes on more than one controller - then the problem is most likely with the SSD (or the files on it if you're working in Windows) rather than a controller problem.
Another thing to try (although I'm not familiar with it) is to see what the SSD does when a bootable Linux distro is used (and if it freezes there also).
Is the drive still under warranty? If so, I'd contact Corsair to see what the requirements are to return it for another one. That'd be the best test IMO.
