Seagate Momentus 2.5 inch hard disk drive is high capacity, high performance random access storage device, which uses non-removable 2.5-inch disks as storage media. Each disk incorporates thin film metallic media technology for enhanced performance and reliability. And for each disk surface there is a corresponding movable head actuator assembly to randomly access the data tracks and write or read the user data.
The Momentus hard disk drive includes the AT controller embedded in the disk drive PCB electronics. The drive's electrical interface is compatible with all mandatory, optional and vendor-specific commands within the ATA specification. Drive size conforms to the industry standard 2.5-inch form factor.; a SATA 15-pin DC power connector, and the standard SATA 7-pin Interface connector. The Momentus hard disk drive incorporates TuMR head and Noise Predictive PRML (Partial Response Maximum Likelihood) signal processing technologies. These advanced technologies allow for areal density of about 700.0 Gigabits per square inch and storage capacity of over 500.0 Gigabytes per disk. The heads, disk(s), and actuator housing are environmentally sealed within an aluminum-alloy base and cover. As the disks spin, air circulates within this base and cover, commonly referred to as the head and disk assembly (HDA), through a non-replaceable absolute filter ensuring a contamination free environment for the heads and disks throughout the life of the drive.
