@Piyoosh,Both are WD Drives,there's a difference in price only!Rest the Drives and capacity-both are same.I read negative reviews about this:WD AV-GP 2 TB Desktop Internal Hard Drive (WD20EURS): Flipkart.com. I recommend this: one:WD Caviar Green 2 TB Desktop Internal Hard Drive (WD20EARX): Flipkart.comas others have suggested me before;i would recommend you to go with seagate instead of WD,because mine WD failed immediately after warranty expiration,both offer 2 year warranty.However,Seagate is a faster one..so go with seagate instead of WD Green/Blue.
