Samsung today announced its new 640-GB, 2.5-inch Spinpoint M7 internal hard disk drive. The new Samsung 640GB hard drive, now the top-density drive of the popular M7 family, has an areal density of 516-Gigabit per square inch for each 320GB platter, which is a 28 percent increase per platter over Samsung’s previous density-leading 500GB hard drive. By maximizing capacity without increasing mechanical parts, the two-platter 640GB drive has lower power consumption levels and higher operational stability compared to drives with a higher number of platters. The new Samsung M7 drive offers a shock resistance level of 400G (2ms) in operation mode and 900G (1ms) when the power is off. An optimized system-on-chip controller reduces the power consumption in both seek and idle modes to the lowest level among comparable drives.
Samsung’s new Spinpoint M7 model is designed for high-end mobile computing applications requiring greater shock resistance without a compromise in performance. The Samsung Spinpoint M7 model offers a rotational speed of 5400RPM, a 3.0Gbps SATA interface, Native Command Queuing and an 8MB cache memory. Initial shipments will be available in Europe and the U.S. from mid September, with worldwide availability starting from late September. The 640GB Spinpoint M7 will begin shipping with a MSRP of $149.99
