SCOPE

1.3SATA

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 133 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 150 MB/s and has a roadmap up to 600 MB/s to support storage evolution of		the
next d e c a d e . 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 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.

DESCRIPTION

CHAPTER 2 DESCRIPTION

This chapter summarizes general functions and key features of the Spinpoint M8 hard disk drive, as well as the standards and regulations they meet.

2.1Introduction

The Samsung Spinpoint M8 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 M8 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 with a SATA 15-pin DC power connector, and the standard SATA 7-pin Interface connector.

The Spinpoint M8 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.

NOTES: Seek time is defined as the time from the receipt of a read, write or seek command until the actuator has repositioned and settled on the desired track with the drive operating at nominal DC input voltages and nominal operating temperature.

Average seek time is determined by averaging the time to complete 1,000 seeks of random length.

Average latency is the time required for the drive to rotate 1/2 of a revolution and on average is incurred after a seek completion prior to reading or writing user data.

Spin up time is the time elapsed between the supply voltages reaching operating range and the drive being ready to accept all commands.

Actual rotational speed can be different a little.

INSTALLATION

CHAPTER 4 INSTALLATION

This chapter describes how to unpack, mount, configure and connect a Spinpoint M8 hard disk drive. It also describes how to install the drive in systems.

4.1Space Requirements

Figure 4-1 shows the external dimensions of the drive.

INSTALLATION

4.2Unpacking Instructions

(1)Open the shipping container of the Spinpoint M8 hard disk drive.

(2)Lift the packing assembly that contains the drive out of the shipping container.

(3)Remove the drive from the packing assembly. When you are ready to install the drive, remove it from the ESD (Electro Static Discharge) protection bag. Take precautions to protect the drive from ESD damage after removing it from the bag.

CAUTION: During shipment and handling, the anti-static ESD protection bag

prevents electronic	component	damage due	to electrostatic discharge.
To avoid accidental	damage to the	drive, do not	use a sharp instrument to
open the ESD protection bag.

(4) Save the packing material for possible future use.

4.3Mounting

Refer to your system manual for complete mounting details.

(1)Be sure that the system power is off.

(2)For mounting, use four M3 screws.

CAUTION: Torque applied to the screws is recommended to be 3.5 [kg* cm] ±0.5 (3.0 [inch *pounds] ±0.5)

INSTALLATION

4.3.2Clearance

The printed circuit board (PCB) is designed to be very close to the mounting holes. Do not exceed the specified length for the mounting screw described in Figure 4-3. The specified screw length allows full use of the mounting-hole threads, while avoiding damage or placing unwanted stress on the PCB.

Figure 4-3: Mounting-Screw Clearance

CAUTION: Using mounting screws that are longer than the maximum lengths specified in Figure 4-3 voids the warranty of the drive.

Spinpoint M8 Product Manual REV 2.3

INSTALLATION

4.3.3 Ventilation

The Spinpoint M8 hard disk drive is designed to operate without the need of a cooling fan provided the ambient air temperature does not exceed 55ºC. Any user-designed cabinet must provide adequate air circulation to prevent exceeding the maximum temperature.

4.4Cable Connectors

The Interface/Power connector consists of two cables; a SATA 15-pin DC power connector, and the standard SATA 7-pin Interface connector.

4.4.1 SATA Connectivity

The SATA interface is connected within a point to point configuration with the SATA host port. There is no master or slave relationship within the devices. Thus SATA does not require master/slave jumper. The drive interface section of the host adapter employs a new design which processed data into a serial datacontrol system.

Figure 4.4 illustrates the connection for the SATA.

There are two cables for SATA drives. One is for data transmission. The other is for power. Figure 4-4 illustrates (a) device signal plug connector, (b) device power plug connector, (c) signal cable receptacle connector mating with (a), and (d) power cable receptacle connector to be mated with (b). For more information, please refer to SATA Specifications cited in the reference.

INSTALLATION

SATA Device Connector Definition

Please note that all pins are in a single row, with a 1.27 mm (50 mil) pitch diameter. There are three power pins for each voltage source. One pin from each voltage is utilized for pre-charge when installed in a blindmate backplane configuration.

The notes on the mating sequence apply to the case of backplane blind mate connector.

When the drive is inserted, the ground pins and the pre-charge pins are in contact first followed by the remaining pins.

Table 4-1 lists the signals connection on the SATA interface and power connector. It is based on SATA 1.0a Specifications. Note that pin numbers is designated from the pin farthest from power segment.

SATA-Bus Interface

Connector

The SATA-Bus interface connector on the drive connects the drive to an SATA host bus adapter or an onboard SATA adapter in the computer. Figures 4.6 illustrates the power, SATA, and factory use only jumper. Figure 4.7 shows pin locations on the SATA drive.
