Third drive worth it?

Hey guys I got two 500gb seagate 7200.11's in raid 0. Just wondering if I would see an increase in speed enough to buy a third drive.

Geeks.com has them for $45, so it seems cheap enough.

Right now-

I would say it's almost not worth it. They'll be a small increase in speed, but you're also increasing the chances of an array failure.

I agree. If you have your hard drives set up in RAID 0 and one of them fails you will lose all the data on all hard drives.

With a third drive would I be able to hit 200 sustained? (currently 166)

I don't care about the risk of failure, I keep all critical data backed up on an external.
