Received replacement hard drives

What a surprise. I just received my replacement hard drives in only 1 day. No, WD didn't ship via overnight. It was shipped via UPS Ground. It was sent from Riverside, CA, which is about 40 minutes from my home. And there is one more surprise. What WD sent me was not 2 150GB Raptors. They sent me 2 300GB VelociRaptor WD3000HLFS!!!! It is like I got free upgrade. My 300GB RAID-0 just became 600GB and faster:-)
