1.0IntroductionThis manual describes the functional, mechanical and interface specifications for the following:Seagate IronWolf Pro Serial ATA model drives:5xxE Standard modelsST8000NE001ST4000NE001ST6000NE000These drives provide the following key features: 7200 RPM spindle speed. Full-track multiple-sector transfer capability without local processor intervention. High instantaneous (burst) data-transfer rates (up to 600MB per second). Native Command Queuing with command ordering to increase performance in demanding applications. Perpendicular recording technology provides the drives with increased areal density. PowerChoice for selectable power savings SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns. State-of-the-art cache and on-the-fly error-correction algorithms. Support for S.M.A.R.T. drive monitoring and reporting. Supports latching SATA cables and connectors. Tarnish-resistant components to help protect drive from environmental elements, increasing field reliability. Worldwide Name (WWN) capability uniquely identifies the drive.NoteSeagate recommends validating the configuration with the selected HBA/RAID controller manufacturer to ensure use of full capacity is supported.Seagate IronWolf Pro SATA Product Manual, Rev.

1.1About the Serial ATA interfaceThe 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 toallow users to install a Serial ATA host adapter and Serial ATA disk drive in the current system and expect all of the existingapplications to work as normal.The Serial ATA interface connects each disk drive in a point-to-point configuration with the Serial ATA host adapter. There is nomaster/slave relationship with Serial ATA devices like there is with parallel ATA. If two drives are attached on one Serial ATA hostadapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This essentiallymeans both drives behave as if they are Device 0 (master) devices.NoteThe host adapter may, optionally, emulate a master/slave environment to host software where twodevices on separate Serial ATA ports are represented to host software as a Device 0 (master) andDevice 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 backwardcompatibility 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 theShadow Register Block. All Serial ATA devices behave like Device 0 devices. For additional information about how Serial ATA emulatesparallel ATA, refer to the “Serial ATA: High Speed Serialized AT Attachment” specification. The specification can be downloaded fromwww.serialata.org.Seagate IronWolf Pro SATA Product Manual, Rev. H6

2.5.2Conducted noiseInput noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the 12 V line or anequivalent 15-ohm resistive load on the 5V line. Using 12V power, the drive is expected to operate with a maximum of 120mV peak-to-peak square-wave injected noise at up to10MHz. Using 5V power, the drive is expected to operate with a maximum of 100mV peak-to-peak square-wave injected noise at up to10MHz.Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.Note2.5.3Voltage toleranceVoltage tolerance (including noise):5V 5%2.5.412V 10%Extended Power Conditions - PowerChoice Utilizing the load/unload architecture a programmable power management interface is provided to tailor systems for reducedpower consumption and performance requirements.The table below lists the supported power conditions available in PowerChoice. Power conditions are ordered from highest powerconsumption (and shortest recovery time) to lowest power consumption (and longest recovery time) as follows: Idle a power Idle b power Idle c power Standby z power. The further users go down in the table, the more power savings is actualized. Forexample, Idle b results in greater power savings than the Idle a power condition. Standby results in the greatest power savings.Power Condition NamePower Condition IDDescriptionIdle a81HReduced electronicsIdle b82HHeads unloaded. Disks spinning at full RPMIdle c83HHeads unloaded. Disks spinning at reduced RPMStandby z00HHeads unloaded. Motor stopped (disks not spinning)Each power condition has a set of current, saved and default settings. Default settings are not modifiable. Default and saved settingspersist across power-on resets. The current settings do not persist across power-on resets. At the time of manufacture, the default,saved and current settings are in the Power Conditions log match.PowerChoice is invoked using one of two methods Automatic power transitions which are triggered by expiration of individual power condition timers. These timer values may becustomized and enabled using the Extended Power Conditions (EPC) feature set using the standardized Set Features commandinterface. Immediate host commanded power transitions may be initiated using an EPC Set Features "Go to Power Condition" subcommandto enter any supported power condition. Legacy power commands Standby Immediate and Idle Immediate also provide amethod to directly transition the drive into supported power conditions.PowerChoice exits power saving states under the following conditions Any command which requires the drive to enter the PM0: Active state (media access) Power on resetSeagate IronWolf Pro SATA Product Manual, Rev.
