While Fujitsu and Hitachi may have announced first, Seagate is first to commercialize its new 7,200RPM, 320GB SATA disk with 16MB cache. The Momentus 7200.3 with G-Force free-fall protection is now available as an option on Dell's "XPS laptops" -- at the moment, it appears limited to the XPS M1730 for a $46 premium over the 320GB 5,400RPM spinner. Alienware laptop rigs should see the new HDD option soon enough.
