CHAPTER 2 DESCRIPTION
This chapter summarizes general functions and key features of the Spinpoint M9TU-USB 3.0 hard disk drive,
as well as the standards and regulations they meet.
2.1 Introduction
The Samsung Spinpoint M9TU-USB 3.0 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 Spinpoint M9TU-USB 3.0 hard disk drive includes the USB 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 USB specification.
Drive size conforms to the industry standard 2.5-inch form factor and mini USB interface.
The Spinpoint M9TU-USB 3.0 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 950 Gigabits per square inch and storage capacity of maximum 667 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.
