Samsung Spinpoint M8 Mobile HDD Series
True mobility in your imagination can be realized with desktop-compatible capacity, quietest operation, and longer battery life.
Imagine a hard drive that combines technology, performance and ecology, Samsung invented it for you with its range of hard drives that consume less energy and are much quieter than a conventional hard disk.
Wings on your mobile. Samsung's Spinpoint M8 series employs advanced format technology (AF) that raises the data storage density per unit area, enabling efficient and convenient data storage. It operates on a high performance 3 gigabits per second SATA interface, provides an eight megabyte buffer memory and incorporates SilentSeek and NoiseGuard features for minimal noise levels. A redesign of the overall structure ensures enhanced shock resistance to protect the disc from physical fracture and data loss.
