Chapter 10 - GLOSSARY
1.3 SATA
The ATA (Advanced Technology Attachment) interface which was developed based on the IDE
(Integrated Drive Electronics) has been around from 1980’s. As the PC processor speed has improved,
so have the data rates of the HDD. The parallel ATA is reaching its limit of 166 MB/s data transfer rate.
Serial implementation of ATA (SATA) will allow the data rate to run even faster so the processor will
be utilized more efficiently. Serial ATA has been developed to provide the next generation storage
interface.
SATA interface replaces 2 inch wide, 40 pin parallel interface connector with 0.25 inch wide 7 pin
serial interface connector. The maximum length of the SATA interface cable can be extended to 1 meter
(approximately 39 inches) compared to 18 inch of parallel ATA. SATA also allows a data transfer
speed of 300 MB/s and has a roadmap up to 600 MB/s to support storage evolution of the next decade.
Even though SATA will not directly interface with Parallel or traditional ATA (PATA) hardware, it is
compliant with ATA protocol and therefore software compatible. The cable geometry with smaller
SCOPE
Barracuda Product Manual Rev04 2
footprint connector reduces board space requirements and improves air flow and heat exchange inside
computer systems.
SATA uses point to point connection topology and each channel works independently. There is no
sharing of interface, master/slave drive configuration, and no master/slave jumper settings. This is
different from Parallel ATA (PATA) architecture where 2 drives per port are supported by a shared bus
and drives are designated as master or slave drive based on jumper pin or cable selection. Unlike
parallel ATA, SATA drives are hot-plug and hot-swappable.
Serial ATA II: Extensions to Serial ATA 1.0a specification incorporate new features including Pin 11
Definition for Activity LED and staggered spin-up control, Phy Event Counters, Software Settings
Preservation, Native Command queuing, Hot-Plugging, and port multiplier, etc.

DESCRIPTION
Barracuda Product Manual Rev04 3
CHAPTER 2 DESCRIPTION
This chapter summarizes general functions and key features of the Barracuda SATA drive. Moreover, it lists
the standards and pertinent requirements.
2.1 Introduction
The Seagate Barracuda 3.5 inch disk drive is high capacity, high performance random access storage devices,
which use non-removable 3.5-inch disk 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
formatted storage capacities of the Barracuda are 1,000 Gigabytes and others. A Gigabyte (GB) contains one
billion bytes or 8 billions bits of data.
The Barracuda drive includes the native SATA interface controller embedded in the disk drive controller chip.
The drive's electrical interface is compatible with all mandatory commands within the SATA specification.
Drive size conforms to the industry standard 3.5-inch form factor. The SATA data signal cables which come
in 0.5 or 1 meter long.
The Barracuda incorporates Tunneling MR head and Noise Predictive PRML (Partial Response Maximum
Likelihood) signal processing technologies. These advanced technologies allow for an areal density of over
167 Gigabits per square inch and storage capacity of over 500 Gigabytes per disk. It also incorporates 48 bit
LBA (logical block address) for more than 137 GB capacities.
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 high efficiency particulate filter ensuring a contamination-free environment for
the heads and disks throughout the life of the drive. A disk damper has been incorporated into the HDD to
reduce the disk vibration. A visco-elastic damper is clamped against the voice coil motor (VCM) assembly so
as to dampen acoustic noise during accessing. A fluid bearing spindle motor is installed to significantly
reduce the acoustic noise commonly found on the ball bearing motor. It further reduces the non-repeatable
run out of the track allowing more tracks to be formatted.
