Thanks for the advice friends
By the way does anybody know if there are any Seagate service centers in Mumbai (near Dadar). It's not like I have made up my mind, but since Seagate doesn't give any home service like WD, then incase of any problem taking the hard disk (or whole cabinet for those like me

who don't know how to remove HDD) to their service center will be a problem if one is located far away. Probably will have to pay some technician 150-200 bucks to remove-reinstall HDD every time.
