  1. Only the ST3500418AS is single platter, designated by the bold number. That means ST31000528AS is two platter.

    WD1001FALS (Caviar Black) is 3 platter. Not sure about the other two Caviar Green drives you listed.
    You can check out this review for all current 1TB, their specs. and real-world speed.

    This points out their power consumption difference between 500GB and 333/375GB platters. Not a lot compared to spindle speed which affects more.
  2. Thank you, wuzy!
  3. EACS is 4 platter, EADS is 3 platter.
