About the Serial ATA Interface

The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface.

The primary advantages include the following:

• Easy installation and configuration with proper 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 users to
install a Serial ATA host adapter and Serial ATA disk drive in the current system and expect all of the existing applications 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 no master/slave relationship with Serial ATA devices like there is with parallel ATA. If two drives are attached to 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 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 reset, 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 International Organization: Serial ATA (Revision 3.2). The specification can be downloaded from www.serialata.org.

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 seeks 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 5000 measurements of seeks between random tracks, with less overhead.

Table 2 Typical seek times

Note

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.

Start/stop times

Standby to ready (sec)| 2.5| 3.0

Power Specifications

The drive receives DC power (+5V) through a native SATA power connector (refer to Figure 3).

Power consumption

Power requirements for the drives are listed in the table in Table 4. Typical power measurements are based on an average of drives tested, under nominal conditions, at 25°C ambient temperature. These power measurements are done with Interface Power Management modes like HIP M and DIPM enabled.

• 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 disk surface and does not execute a read or write operation. Servo electronics are active. Seek mode power is measured based on three random seek operations every 100 ms. This model is not typical.

• Read/write power and current
  Read/write power is measured with the heads on track, based on three 63-sector read or write operations every 100 ms.

• 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.

Table 4 DC Power Requirements

Sleep| 0.13W

1. During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.
2. Standby power is measured at a steady state (after 200ms from transition)

Typical current profiles

The typical 5V startup and operation current profile is shown in Figure 1 and Figure 2.

Figure 1 Typical 1D – 5V Startup and Operation Current Profile

Figure 2 Typical 2D – 5V Startup and Operation Current Profile

Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line.

• 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 20 MHz.

Note: Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

Supply Voltage

Power management modes

The drive provides programmable power management to provide greater energy efficiency. In most systems, power management is controlled through the system setup program. The drive features the following power-management modes:

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 disk 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 specific 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 disk 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 driving activity is required, the drive makes a transition to standby mode. In both Idle and standby modes, the drive accepts all commands and returns to active mode when disk access is necessary.

Environmental Specifications

This section provides the temperature, humidity, shock, and vibration specifications for BarraCuda drives. Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Above 1000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet.

• Note: Seagate does not recommend operating at sustained case temperatures above 60°C. Operating at higher temperatures will reduce the useful life of the product.
• Note: The recommended storage period:
  • 1 year under controlled conditions of 34°C 90%RH or less
  • 90 days in uncontrolled storage conditions

Shock

All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may b e applied in the X, Y, or Z axis.

Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 400 Gs based on half-sine shock pulses of 2ms. Shocks should not be repeated more than one time per axis.

Non-operating shock

The non-operating shock level that the driver can experience without incurring physical damage or degradation in performance when subsequently put into operation is 1000 Gs based on a nonrepetitive half-sine shock pulse of 1 ms duration.

Vibration

All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y, or Z axis.

Operating vibration

The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below.

Non-operating vibration

The maximum non-operating vibration levels that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation are specified below.

5–500 Hz: 5.0 Gs (0 to peak). Max displacement may apply below 22 Hz.

Acoustics

Drive emission of sound is measured consistently with the ECMA-74 and its referenced standards. Testing is conducted at room temperature (approximately 25°C). Emission levels are reported as the total A-weighted sound power levers for steady state, idle, and active seeks modes of operation.

1. During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

Test for prominent discrete tones (PDTs)

Seagate follows the ECMA-74 standards for the measurement and identification of PDTs. An exception to this process is the use of the absolute threshold of hearing. Seagate uses the lower limit for the threshold curve to discern tone audibility and to compensate for the inaudible components of sound prior to the computation of tone ratios according to Annex D of the ECMA-74 standards.
Defined as the median curve given by ISO 389-7 (Tf curve) minus 10dB at all frequencies.

Electromagnetic Immunity

When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the radio frequency (RF) environment as defined in Table 7.

FCC verification

These drives are intended to be contained solely within a personal computer or similar enclosure (not attached as an external device). As such, each drive is considered to be a subassembly even when it is individually marketed to the customer. As a subassembly, no Federal Communications Commission verification or certification of the device is required.

Seagate has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disk drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of the FCC rules. Operation with noncertified assemblies is likely to result in interference to radio and television reception.

Radio and television interference. This equipment generates and uses radio frequency energy and if not installed and used in strict accordance with the manufacturer’s instructions, may cause interference to radio and television reception.

This equipment is designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television, which can be determined by turning the equipment on and off, users are encouraged to try one or more of the following corrective measures:

• Reorient the receiving antenna.
• Move the device to one side or the other of the radio or TV.
• Move the device farther away from the radio or TV.
• Plug the computer into a different outlet so that the receiver and computer are on different branch outlets.

If necessary, users should consult the dealer or an experienced radio/television technician for additional suggestions. Users may find helpful th e following booklet prepared by the Federal Communications Commission: How to Identify and Resolve Radio-Television Interference Problems. Thi s booklet is available from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication number 004-000-00345-4.

Corrosive Environment

Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years of 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.

Configuring and Mounting the Drive

This section contains the specifications and instructions for configuring and mounting the drive.

Handling and Static-Discharge Precautions

After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions.

CAUTION

• Keep the drive in the electrostatic discharge (ESD) bag until ready for installation to limit the drive’s exposure to ESD.
• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure.
• Handle the drive by its edges or frame only.
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until mounting it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some factory-installed labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination.

Configuring the Drive

Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationship. If two drives are attached to one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. Both drives behave as if they are Device 0 (master) devices.

Serial ATA Cables and Connectors

The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 in). Refer to Table 10 for connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host.

For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host receptacle incorporate features that enable the direct connection to be hot-pluggable and blind- mateable. For installations that require cables, users can connect the drive as shown in Figure 3.

Figure 3 Attaching SATA Cabling

Each cable is keyed to ensure correct orientation. BarraCuda drives support latching SATA connectors.

Drive Mounting

Users can mount the drive in any orientation using four screws in the side- mounting holes or four screws in the bottom-mounting holes. Refer to Figure 4 and Figure 5 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:

• Allow a minimum clearance of 0.030 in (0.76 mm) around the entire perimeter of the drive for cooling.
• Use only M3 x 0.5 mounting screws.
• Do not overtighten the mounting screws. Maximum torque: 4.0 in-lb (0.4519 N-m).
• Four (4) threads (0.080 in, 2.032 mm) minimum screw engagement recommended.
• Avoid excessive drive distortion when mounting. Refer to the following specifications for stiffness/deflection information:

Top cover stiffness/deflection|
---|---
Operating: no performance degradation, emitted noise, mechanical damage, or hard errors| 10 mm probe: 2.0kgf (typical)
Non-operating: no hard errors| 10 mm probe: maximum 2.0kgf (instantaneous)

Figure 4 Mounting Dimensions (for 1-disk models).

Figure 5 Mounting Dimensions (for 2-disk models)

Serial ATA (SATA) Interface

These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–6. The drive also supports the use of the IORDY signal to provide reliable high-speed data transfers.
For detailed information about the Serial ATA interface, refer to the Serial ATA: High Speed Serialized AT Attachment specification.

Hot-Plug Compatibility

BarraCuda drives incorporate connectors that enable users to hot plug these drives in accordance with the Serial ATA: High-Speed Serialized A T Attachment specification revision 2.0. This specification can be downloaded from www.serialata.org. This device requires a COMRESET from the host after a hotplug event.

Notes

1. All pins are in a single row, with a 1.27 mm (0.050 in) pitch.

2. The comments on the mating sequence apply to the case of the backplane blind mate connector only. In this case, the mating sequences are:

   • the ground pins P4 and P12.
   • the pre-charge power pins and the other ground pins.
   • the signal pins and the rest of the power pins.

3. There are three power pins for each voltage. One pin from each voltage is used for pre-charge when installed in a blind-mate backplane
   configuration.

4. All used voltage pins (Vx) must be terminated.

Identify Device command

The Identify Device command (command code ECH) transfers information about the drive to the host following power-up. The data is organized as a single 512-byte block of data, whose contents are shown in Table 12. All reserved bits or words should be set to zero. Parameters listed with an “x ” are drive- specific or vary with the state of the drive. Refer to Drive Specifications on page 6 for default parameter settings. The following commands contain drive- specific features that may not be included in the Serial ATA specification.

Set Features command

This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY, and generates an interrupt. If the value in the register does not represent a feature that the drive supports, the command is aborted. Power-on default has the read look-ahead and writes caching features enabled. The acceptable values for the Features register are defined as follows:

Table 14 Set Features command values

register values:

00H Set PIO mode to default (PIO mode 2).

01H Set PIO mode to default and disable IORDY (PIO mode 2). 08H PIO mode 0

09H PIO mode 1 0AH PIO mode 2 0BH    PIO mode 3

0CH   PIO mode 4  (default) 20H Multiword DMA mode 0 21H Multiword DMA mode 1 22H Multiword DMA mode 2 40H Ultra DMA mode 0

41H Ultra DMA mode 1 42H Ultra DMA mode 2 43H Ultra DMA mode 3 44H Ultra DMA mode 4 45H    Ultra DMA mode 5

46H    Ultra DMA mode 6

Note:  At power-on, or after a hardware or software reset, the default values of the features are as indicated above

S.M.A.R.T. provides near-term failure prediction for disk drives. When S.M.A.R.T. is enabled, the drive monitors predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T. predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T. commands and implementation, see the Draft ATA-5 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4H) that eliminates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at: http://www.seagate.com/support/downloads/seatools/.

This drive is shipped with S.M.A.R.T. features disabled. Users must have a recent BIOS or software package that supports S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses.

Table 15 S.M.A.R.T. Commands

Note: If an appropriate code is not written to the Features Register, the command is aborted and 0 x 04 (abort) is written to the Error register

FAQ’s

What is the aim of Seagate BarraCuda?

BarraCuda hard drives from Seagate are suited for a range of storage applications, including all-in-one storage and mobile storage.

What is the transfer rate of the Seagate BarraCuda?

The Seagate BarraCuda 1TB may offer some of the cheapest HDDs on the market with the fastest performance. The 64 MB cache, 7200 rpm spin speed, and SATA 6GB/s transfer speeds minimise lag and load times whether you’re gaming or editing.

How durable is a Seagate hard drive?

Hard disc drive mechanisms typically have MTBF ratings between 300,000 and 1,200,000 hours, which can give the impression that the specification ensures between 30 and 120 years of uninterrupted operation.

How long do Seagate Barracuda drives last?

For instance, when operating 2,400 hours annually and under “typical” workload conditions, the Seagate BarraCuda has an AFR of less than 1.0% throughout a five-year service life. Western Digital (WD) reports that the expected number of load/to-unload cycles for its WD Black performance drives is 300,000.

What kind of drive is a Seagate Barracuda drive?

The Seagate Barracuda is a series of hard disc drives that Seagate Technologies first introduced in 1993 and later upgraded to solid-state drives.

What causes Seagate hard drives to fail?

A virus or malicious software that erases and steals data from your hard disc could cause data loss.

What is the transmission rate of the barracuda?

There are enough backups to fit in the 1TB of storage. 7200 rpm spin rates result in rapid performance. A 64MB cache reduces lag and load times. Transfer speeds of up to 6GB/s (600MB/s) are supported.

SSDs or HDDs, Seagate Barracudas?

Seagate’s Barracuda SATA SSD outperforms HDDs by up to 20%. According to internal PCMark8 storage 2.0 bandwidth tests, the SSD has a BC speed of 169.2MB/s versus 8.34MB/s for the HDD.

Can Seagate get my data back?

As a result, Rescue Data Recovery Services are now included with the majority of Seagate discs.

Do Seagate drives frequently fail?

Although the majority of issues were with smaller drives (those under 12TB), overall failure rates were very low, with an average AFR of 1.01% across all drives.

Inevitably, Seagate hard drives malfunction.

External hard drives are mechanical devices with moving elements. They are therefore likely to finally collapse. It’s a good idea to have a backup plan in case your computer crashes. Because they include moving elements, external hard drives are more likely to sustain physical damage.

How do ports get access to Seagate?

A Seagate device can be connected to any computer that has a USB-C, Thunderbolt 3, or USB-A (USB 3.0 or USB 2.0) port.

Will data on an HDD be lost if there is no power?

Unlike RAM, hard drives can hold data without electricity once information has been written to them.

Is BarraCuda an SSD?

BarraCuda SSD products are readily available in 2.5 SATA and M. 2 2280 form factors, making them perfect for tiny PCs, desktop PCs, and incredibly thin and small laptops that require next-generation SSD speed for accelerated programs and multitasking.

Does Seagate perform regular backups?

There is no Protect. if you have already created a backup plan. It can be difficult to start a new job, a family, or even just go to the grocery store.
