2.1 Introduction
The Samsung Spinpoint M8U 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 t e c h n o l o g y for e n h a n c e d p e r f o r m a n c e and r e l i a b i l i t y . And f o r e a c h
d i s k s u r f a c e t h e r e i s a corresponding movable head actuator assembly to randomly access the data
tracks and write or read the user data.

Drive size conforms to the industry standard 2.5-inch form factor and mini USB interface.
The Spinpoint M8U 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 maximum 500.0 Gigabytes per disk.

The heads, disk(s), and actuator housing are environmentally s ealed 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.
