Product Description

Seagate Laptop HDD ST4000LM016

This Seagate laptop HDD drive is a high-capacity, high-performance random access storage device, which uses non-removable 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 laptop HDD 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. The Laptop HDD incorporates TuMR head and Noise Predictive PRML (Partial Response Maximum Likelihood) signal processing technologies. These advanced technologies allow ample storage capacity. 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.
