“What if I told you that you could have Velociraptor level performance (and more) with almost seven times the capacity? Seagate's Constellation Hard Drive fits that bill to a T. It Outperforms the Velociraptor by almost 20mb/s on maximum read performance, and with 2TB of space it puts the 300GB capacity of the Velociraptor to shame.”
- Lanoc Reviews, January 2010
