^ Warranty was never so great with Seagate , one had to waste 2 days at the service centre to submit the HDD and take it back from RMA.

.
WD provides door to door replacement,and one of the best service Ive ever experienced .Let me tell you a recent incident .My 640GB AAKS developed bad sectors so before filling the RMA request form ,i sent a mail to WD India asking them about the high failure rates of the Blue AAKS drives.The next day I got a call from some manager at WD ,Delhi who promised me a 1TB Green drive as replacement in lieu of the 640GB AAKS if I face issues with the Blue ones.
I explained to him that a GREEN drive will be slowed than AAKS series so he obliged to send a 1TB BLACK . To top it all , the courier guy came the very next day to collect the defective drive and a replacement 1TB Black was shipped to me on the same day itself. ie- Advance replacement.

hyeah:
Now that's called Awesome Customer service. After this incident ,Ive become a complete WD fan and changed all my drives to WD .Total 3 X 1TB drives.1 Black and 2 Green.
@Gaurish , sorry for the OT. hope you don't mind .All I want to say here is that there is no reason as such to get Seagate drives these days especially with the issues with reduced warranty and Accel Frontline denying so many drives from RMA.
