No hej no datasheet je tu http://www.samsung.com/global/business/hdd/product model.do?group=72&type=94&subtype=98&model_cd=512& ppmi=1184
(Specifications - downlad PDF), robi sa 1,5TB a 2TB (mozeme 3x hadat ze preco), formatted capacity per disk je 500GB t.j. ma to asi 2 platne ( = 4 strany po 500GB) a 1,5TB pouziva asi len 3 strany, ale to je len moja spekulacia. Je to ale jedno neries to ked si to uz objednal tak to nechaj tak je to OK, nemaj strach. Samsung vie co robi, nepredava ziadne sroty.
