I'm going to buy a new HDD. I already have a Seagate Barracuda 500 GB + WD Caviar Blue 150 GB. Should I get an extra Barracuda and raid 0 it or get a 1.5 TB WD Black? Which would give me more speed? I'm asking in terms of the advantage of Seagate Barracuda 500 GB Raid 0 vs a WD Black 1.5 TB. Would I really see big difference in Barracuda Raid 0?

RAID 0 disadvantages: Double the chances of losing your data. Lose one drive and you've lost all the data on BOTH drives. Relatively complex to set up as compared to a single drive. RAID array is not transferable to a different PC.
All in all, the increase in speed is not great enough to overcome the disadvantages, IMHO.
Another way to go is a hybrid ....a SSD and HD in a single form factor......just $10 more than the Black but ya give up half the size ....while synthetic benchmarks won't show a great difference, "real world" benchies show the Momentus trouncing the Black or any other standard drive.
