You can generally RAID0 any 2 like drives (meaning on the same RAID capable controller at the same time). That said, the array will be the 2x the size of the smallest drive in the array, and will run at the speed of the slowest drive in the array. If you are running Windows 7 on an Intel 7-Series chipset you will be able to utilize TRIM, if not you will lose TRIM and have to depend on the garbage collection routines of the drive.
Sounds good, I'll try and give it a shot, although should one fail that would also mean the data on both drives would be lost... How stable would you expect a pair of SSDs to be? I've had a rough time with data loss in the past along side the traditional disk drive...
Yes, if you lose one drive in a standard RAID0 you lose all the data on both drives. All drives will eventually fail. You should be making daily backups of your data in case of failure in any case, RAID0 or not.
I would not recommend doing this - this really is just going to negate any of the benefits of the Max IOPS drive's better NAND. It will still be much faster than either drive individually though, so it really depends if you want consistency and longevity or speed.
