Can you Put a 32MB Cache Harddrive with a 64MB Cache HDD in Raid 0?

Just wondering because im going to buy the 1.5tb western digital black caviar 64MB Cache from newegg, and Currently I got an older 1tb western digital black caviar 32MB Cache, I'm wondering if they can both go in raid 0 without any problems. There both 7200RPM btw.

Yes, they are both compatible with Raid 0 file systems.

Yes you can.Here's the deal:a.) The total performance of the array will be determined by the lower performing drive, the older drive in this case.b.) The total size of the array will be 2.0TB, not 2.5TB***
