^^ Hitachi is a better option, but remember if you source from Newegg you'll loose the warranty for the hard drive.
Seagate is available in India, and thus, has a good after sales support system in place. I've no clue about Hitachi on this one. But drive-to-drive Hitachi Deskstar series drives perform over the Seagate Barracuda drives.
