Both Samsung and Toshiba recently
that they’d be among the first to release 2.5-inch 640GB hard drives for the mobile market.
Samsung’s new 640GB 2.5-inch Spinpoint M7 internal drive has a density of 516-Gigabit per square inch for each of the 320GB platters, which is a 28 percent increase per platter over it’s previous record setting 500GB internal drive. The density change allowed Samsung to up the storage capacity without adding additional platters.
On September 2nd Toshiba began shipping out their new sample 640GB 2.5-inch drive to OEMs and distributors. Given its density of 817.0 Mbit/mm2, the new drive will bring performance improvements over their previous generation of 5,400RPM drives, and will lower energy consumption by 28 percent.
