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

Typical seek times (ms)	Read
Track-to-track	1.5
Average	13.0
Average latency	5.6

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

Table 3 Start/stop times

Capacity	1-disk models	2-disk models	1-disk models	2-disk models
Typical seek times (ms)	Typical		Max @ 25°C
Power-on to ready (sec)	2.8	3.3	3.0	3.5
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

Power Dissipation	1-disk models +5V input average (25° C)	2-disk models +5V input average (25° C)
Spinup (max)	1.00A
Write average	1.70W	1.80W
Read average	1.60W	1.70W
Idle, performance (1)	1.40W	1.50W
Idle, active	0.69W	0.85W
Idle, low power mode	0.45W	0.50W
Standby(2)	0.13W
Sleep	0.13W

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.
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

Allowable voltage	5V ± 5%
Allowable noise/ripple	100 p-p max, 0-20 MHz
Allowable supply rise time	<100 ms

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:

Power modes	Heads	Spindle	Buffer
Active (operating)	Tracking	Rotating	Full power
Idle, performance	Tracking	Rotating	Self-refresh—low power
Idle, Active	Floating	Rotating	Self-refresh—low power
Idle, low power	Parked	Rotating	Self-refresh—low power
Standby	Parked	Stopped	Self-refresh—low power
Sleep	Parked	Stopped	Self-refresh—low power

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.

Table 5: Environmental specifications

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.

5–200 Hz	2.0 Gs (0 to peak). Max displacement may apply below 10 Hz.
201–500 Hz	1.0 Gs (0 to peak).

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.

X: Indicates that the hazardous substance contained in at least one of the homogeneous materials used for this part is above the limit requirement of GB/T26572.

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)

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

All pins are in a single row, with a 1.27 mm (0.050 in) pitch.
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.
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.
All used voltage pins (Vx) must be terminated.

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

02H	Enable write cache (default).
03H	Set transfer mode (based on value in Sector Count register). Sector Count 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
55H	Disable read look-ahead (read cache) feature.
82H	Disable write cache
AAH	Enable read look-ahead (read cache) feature (default).
C1H	Disable the Free Fall Protection feature (41H above enables the Free Fall Protection feature)
F1H	Report full capacity available

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

Code in features register	S.M.A.R.T. command
D0H	S.M.A.R.T. Read Data
D2H	S.M.A.R.T. Enable/Disable Attribute Autosave
D3H	S.M.A.R.T. Save Attribute Values

FAQ’s

What is the purpose of Seagate BarraCuda?

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

What is Seagate BarraCuda’s transfer rate?

Some of the quickest speeds in the market for cheap HDDs may be found with the Seagate BarraCuda 1TB. While you’re gaming or editing, the 7200 rpm spin speed, 64 MB cache, and SATA 6GB/s transfer rates reduce lag and load times.

How long does a Seagate hard disc last?

Hard disc drive mechanisms frequently have MTBF ratings between 300,000 and 1,200,000 hours, which could lead one to believe that the specification guarantees between 30 and 120 years of uninterrupted operation.

How durable are Seagate Barracuda drives?

For instance, the Seagate BarraCuda has an AFR of less than 1.0% throughout a five-year service life when operating 2,400 hours per year and under “normal” workload conditions. For its WD Black performance drives, Western Digital (WD) reports the anticipated number of load/to unload cycles, which comes in at 300,000.

A Seagate Barracuda drive is what kind of drive?

The Seagate Barracuda is a line of hard disc drives first released in 1993 and later upgraded to solid-state drives by Seagate Technologies.

Do Seagate hard drives fail for what reasons?

Data loss could result from a virus or malware deleting and stealing information from your hard drive.

What is the barracuda’s transfer rate?

The 1TB storage is sufficient for numerous backups. Spin speeds of 7200 rpm produce quick performance. Lag and load times are reduced via a 64MB cache. Up to 6GB/s (600MB/s) of transfer speeds are supported.

Are Seagate Barracudas HDDs or SSDs?

The Barracuda SATA SSD from Seagate outperforms HDDs by up to 20 percent. Based on internal PCMark8 storage 2.0 bandwidth tests, the SSD has a 169.2MB/s BC speed compared to the HDD’s 8.34MB/s.

Are Seagate drives prone to failure?

Although smaller drives (those under 12TB) accounted for the bulk of problems, overall failure rates were minimal, with an average AFR of 1.01% across all drives.

Seagate hard drives inevitably fail.

Hard drives that are external are mechanical and have moving parts. This implies that they will eventually fail. Your external hard disc will eventually fail; the question is not if, but rather when. External hard drives are more prone to physical harm because they have moving parts.

How does Seagate access ports?

Any computer having a USB-C, Thunderbolt 3, or USB-A (USB 3.0 or USB 2.0) connector can be used to connect a Seagate device.

Without electricity, will an HDD lose data?

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

BarraCuda—is it an SSD?

BarraCuda SSD products are available in 2.5 SATA and M. 2 2280 form factors, making them ideal for mini PCs, desktop PCs, and ultra-thin and ultra-compact laptops that require next-generation SSD speed for accelerated apps and multitasking.

Does Seagate perform regular backups?

Protect is not present. If you have previously developed a backup strategy. Getting a hold of a new job, starting a family, or just going to the grocery store can be stressful.

Can Seagate get my data back?

Thus, the majority of Seagate discs now come with Rescue Data Recovery Services.
