J iii 1.0 Introduction This manual describes the functional, mechanical and interface specifications for the following Seagate Barracuda® 7200.10 Serial ATA model drives: ST3750640AS ST3750840AS ST3500630AS ST3500830AS ST3400620AS ST3400820AS ST3320620AS ST3320820AS ST3300620AS ST3300820AS ST3250620AS ST3250820AS ST3250410AS ST3250310AS ST3200820AS ST3160815AS ST3160215AS ST3120815AS ST3120215AS ST380815AS ST380215AS ST340815AS ST340215AS These drives provide the following key features: · 7,200 RPM spindle speed. · High instantaneous (burst) data-transfer rates (up to 300 Mbytes per second). · Perpendicular recording and Tunneling Magnetoresistive (TMR) recording heads for increased areal density. · State-of-the-art cache and on-the-fly error-correction algorithms. · Native Command Queueing with command ordering to increase performance in demanding applications. · Full-track multiple-sector transfer capability without local processor intervention. · Quiet operation. · SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns. · Support for S.M.A.R.T. drive monitoring and reporting. · Supports latching SATA cables and connectors. Barracuda 7200.10 Serial ATA Product Manual, Rev. J 1 1.1 About the Serial ATA interface The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include: · Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jumpers or other configuration options. · Thinner and more flexible cabling for improved enclosure airflow and ease of installation. · Scalability to higher performance levels. In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial ATA was designed to allow you to install a Serial ATA host adapter and Serial ATA disc drive in your current system and expect all of your existing applications to work as normal. The Serial ATA interface connects each disc drive in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship with Serial ATA devices like there is with parallel ATA. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both "masters" on two separate ports. This essentially means both drives behave as if they are Device 0 (master) devices. Note. The host adapter may, optionally, emulate a master/slave environment to host software where two devices on separate Serial ATA ports are represented to host software as a Device 0 (master) and Device 1 (slave) accessed at the same set of host bus addresses. A host adapter that emulates a master/slave environment manages two sets of shadow registers. This is not a typical Serial ATA environment. The Serial ATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward compatibility with existing host systems and software. The Command and Control Block registers, PIO and DMA data transfers, resets, and interrupts are all emulated. The Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For additional information about how Serial ATA emulates parallel ATA, refer to the "Serial ATA: High Speed Serialized AT Attachment" specification. The specification can be downloaded from www.serialata.org. 2 Barracuda 7200.10 Serial ATA Product Manual, Rev.

J 2.6 Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows: · Track-to-track seek time is an average of all possible single-track seeks in both directions. · Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead. 750 - 300 GB models*, ST3250620AS, ST3250820AS and 200 GB model Typical seek times (msec) Track-to-track Average Average latency: *Measured in performance mode. **Measured in quiet mode.

These drives are designed to consistently meet the seek times represented in this manual. Physical seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted values. However, due to the manner in which these drives are formatted, benchmark tests that include command overhead or measure logical seeks may produce results that vary from these specifications. 2.7 Start/stop times 750 - 320 GB models 300 GB model ST3250620AS, ST3250820AS and 200 GB model 11 (max) 11 (max) ST3250410AS, ST3250310AS and 160 - 40 GB models 7.9 (max) 7.9 (max) Power-on to Ready (sec) Standby to Ready (sec) Ready to spindle stop (sec) 15 (max) 15 (max) 10 (max) Barracuda 7200.10 Serial ATA Product Manual, Rev.

See Figure 4 on page 42. 2.8.1 Power consumption Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature. · Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed. · Seek mode During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does not execute a read or write operation. Servo electronics are active. Seek mode power represents the worst-case power consumption, using only random seeks with read or write latency time. This mode is not typical and is provided for worst-case information. · Read/write power and current Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-msec delay, then a 16-sector read followed by a 32-msec delay. · Operating power and current Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10 reads) and 20 percent drive idle mode. · Idle mode power Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location. · Standby mode During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/ write electronics are in power-down mode.

Typical 12V startup and operation current profile 2.8.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line. · Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up to 10 MHz. · Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at up to 10 MHz. Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current. 2.8.3 Voltage tolerance Voltage tolerance (including noise): 5V ± 5% 12V ± 10% Barracuda 7200.10 Serial ATA Product Manual, Rev. J 31 2.8.4 Power-management modes The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control power management through the system setup program. The drive features the following power-management modes: Power modes Active Idle Standby Sleep Heads Tracking Tracking Parked Parked Spindle Rotating Rotating Stopped Stopped Buffer Enabled Enabled Enabled Disabled · Active mode The drive is in Active mode during the read/write and seek operations. · Idle mode The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc access is necessary. · Standby mode The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for a specifiable length of time. The standby timer delay is established using a Standby or Idle command. In Standby mode, the drive buffer is enabled, the heads are parked and the spindle is at rest. The drive accepts all commands and returns to Active mode any time disc access is necessary. · Sleep mode The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buffer is disabled, the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep mode and enters Standby mode with all current translation parameters intact. · Idle and Standby timers Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and begins counting down from its specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disc access is necessary. 32 Barracuda 7200.10 Serial ATA Product Manual, Rev.

The following table contains information mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic Information Products" Standard. "O" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is lower than the threshold defined by the China RoHS MCV Standard. "O"RoHS MCV "X" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is over the threshold defined by the China RoHS MCV Standard. "X "RoHS MCV 2.15 Corrosive environment Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment. Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives. Barracuda 7200.10 Serial ATA Product Manual, Rev.
