I saw WD3200BEVE drives (the biggest one of the one we are talking about) with manufacturing date from 2011...
at OP: all 2,5" IDE drives that do not exceed height of 9mm are ok. The fastest, coolest and quietest is both the WD3200BEVE and the Samsung HM160HC, -HJ, -HI. One of them Samsungs has one platter design and is the one that is as fast as the WD scorpio blue 320GB (which has two 160GB platters). I find the Samsung a bit quieter as the WD, but that might only be the one I have, because the WD allready had a high number of power on hours. Also sound experience is subjective.
