Samsung Electronics Co., Ltd., a world leader in digital consumer electronics and information technology, today announced its new 640-Gigabyte (GB) 2.5-inch Spinpoint M7 internal hard disk drive. The new 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. Samsung’s new Spinpoint M7 model is designed for high-end mobile computing applications requiring greater shock resistance without a compromise in performance.
“With the addition of the new internal drive to the M7 series, our customers will get the best viable combination of density, performance and reliability that is essential for high-end notebooks and mobile applications,” said C.H. Lee, vice president, Storage sales & marketing, Samsung Electronics. “Samsung maximizes the density level of its platters to enhance the reliability and stability of its internal hard drives.”
Increasing the areal density of 516-Gigabit per square inch raises the total drive capacity without adding additional platters. 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.
