When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be available for data storage. Actual quantities will vary based on various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating environment and other factors.

• High instantaneous (burst) data-transfer rates (up to 6Gb/s).
• MTC TechnologyTM, proprietary data flow management.
• Native Command Queuing (NCQ) with command ordering.
• Quiet operation. Fluid Dynamic Bearing (FDB) motor.
• SeaToolsTM diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
• Shingled magnetic recording with perpendicular magnetic recording heads/media.
• State-of-the-art cache and on-the-fly error-correction algorithms.
• Support for Read Multiple and Write Multiple commands.
• Support for S.M.A.R.T. drive monitoring and reporting.
• Worldwide Name (WWN) capability uniquely identifies the drive.

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 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 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.
The host adapter may, optionally, emulate a master/slave environment to host software where two devices on separate Serial ATA ports
Note
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 International Organization: Serial ATA (Revision 2.6). The specification can be downloaded from www.serialata.or
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.

1. One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.
Note
If the drive is powered-off before issuing flush cache command, in some instances, the end user data in the DRAM cache might not be committed to the disk.
The specifications for the product assumes the I/O workload does not exceed the average annualized workload rate limit of 55 TB/year. Workloads exceeding the annualized rate may degrade and impact reliability as experienced by the particular application. The average annu­alized workload rate limit is in units of TB per calendar year.

Refer to Configuring and Mounting the Drive on page 21 (words 60-61 and 100-103) for additional information about 48-bit addressing support of drives with capacities over 137 GB.

2.5 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 5000 measurements of seeks between random tracks, less overhead.
Table 2 Typical seek times
Typical seek times (ms) Read
Track -to-t rack 1.5
Average 13.0
Average latency 5.6
These drives are designed to consistently meet the seek times represented in this manual. Physical
Note
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 Power Specifications

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

2.7.1 Power consumption

Power requirements for the drives are listed in the table in Tab le 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 DIPM enabled.
Spinup current is measured from the time of power-on to the time that the drive spindle reaches operating speed.
Read/Write current is measured with the heads on track, based on three 64 sector read or write operations every 100 ms.
The drive supports three idle modes: Performance Idle mode, Active Idle mode and Low Power Idle mode. Refer to Section 2.7.4 for power­management modes.
