The Seagate Momentus 5400.2 series hard drives enable the freedom of mobility and enhanced productivity with 5400-RPM performance. The ST9120821AS is a 120GB drive that has an 8MB cache and SATA150 interface to enable high-speed access to your data.
Seagate has used a SoftSonic fluid dynamic bearing (FDB) motor and QuietStep ramp load technology to engineer a drive with minimal vibration and noise. The FDB also increases the shock tolerance of the drive.
Low seek power (2.2W) and stand-by power (0.28W) enhance battery life and also make it perfect for use in external storage enclosures.
