2 plater 2TB drives

when is WD going to have a 1TB per plater drives like Seagate - I like WD better with off plater head parking - i bought a 2Tb Seagate with 1Tb per plater and it is faster than my WD 600MB scorpio drive - WD is falling behind - I don’t like Seagate HD but I wanted to see if the 1TB per plater had a higher transfer rate and it does but made in China and only 2 year warranty -  come on guys get HOT - PS you guys are getting like Seagate on listing specs - they put very little down and now you guys are doing the same - shame of WD
