Seagate Momentus 5400.6 Hard Drives
With fourth-generation perpendicular magnetic recording technology and capacities up to 500 GB, the Seagate Momentus 5400.6 drive offers the best combination of performance, capacity, mobility and durability in a laptop hard drive. The Momentus 5400.6 drive offers a fast SATA 3Gb/s interface plus an 8-MB cache, making the drive ideal for mainstream laptops, workstations, gaming laptops and personal external storage.
Up to 1000 Gs of Shock Resistance - The Seagate Momentus 5400.6 drive offers the best combination of performance, capacity, mobility and durability in a laptop hard drive. Using optional G-Force Protection technology, this drive provides added durability and robustness in the event of the accidental drops that can occur in strenuous mobile environments. With capacities from 120 GB to 500 GB, the Momentus 5400.6 drive meets the demanding requirements of today’s notebook multimedia usage models. Built with proven Seagate perpendicular recording technology and able to withstand up to 1000 Gs of shock, this highly reliable 2.5-inch drive is perfect for notebook or external storage applications.
G-Force Protection Technology - When a laptop is dropped, the most catastrophic damage to the hard drive occurs when the head scrapes across the surface of the disk, causing potential data loss. G-Force Protection technology protects the hard drive against shock by sensing when the system is in a free-fall state, moving the heads off the platter and locking them in place. All this happens within three-tenths of a second when a change in acceleration equal to the force of gravity is sensed. G-Force Protection technology results in added durability and reliability during accidental drops.
  Key Features and Benefits
- 8-MB cache delivers fast performance.
- Robust design and high shock tolerance enable mobility in rugged operating environments.
- 1000 Gs of nonoperating shock make the drive ideal for notebook PCs and industrial applications.
- G-Force Protection feature available for added robustness in mobile environments
- Green feature leverages Seagate laptop power management technology.
- Ramp load features that remove the head from the disk during idle periods, improving idle power consumption and adding to the durability of the drive.
- QuietStep technology enables ultra-quiet load/unload acoustics.
- SATA 3Gb/s interface with Native Command Queuing.
- Fourth-generation perpendicular recording technology.
- High instantaneous (burst) data transfer rates up to 3 Gb/s.
