Travelstar 5K160 (SATA) Hard Disk Drive Specification

14.40.1.2S.M.A.R.T. Read Attribute Thresholds (Subcommand D1h)

This subcommand returns the device’s Attribute Thresholds to the host. Upon receipt of the S.M.A.R.T. Read Attribute Thresholds subcommand from the host, the device reads the Attribute Thresholds from the Attribute Threshold sectors and then waits for the host to transfer the 512 bytes of Attribute Thresholds information from the device.

14.40.1.3S.M.A.R.T. Enable/Disable Attribute Autosave (Subcommand D2h)

This subcommand enables and disables the attribute autosave feature of the device. The S.M.A.R.T. Enable/Disable Attribute Autosave subcommand allows the device to automatically save its updated Attribute Values to the Attribute Data Sector at the timing of the first transition to Active idle mode after 30 minutes since the last saving of Attribute Values; this subcommand causes the autosave feature to be disabled. The state of the Attribute Autosave feature (either enabled or disabled) will be preserved by the device across power cycle.

A value of 00h written by the host into the device’s Sector Count Register before issuing the S.M.A.R.T. Enable/Disable Attribute Autosave subcommand will cause this feature to be disabled. Disabling this feature does not preclude the device from saving Attribute Values to the Attribute Data sectors during some other normal operation such as during a power-up or power-down.

A value of F1h written by the host into the device’s Sector Count Register before issuing the S.M.A.R.T. Enable/Disable Attribute Autosave subcommand will cause this feature to be enabled. Any other non-zero value written by the host into this register before issuing the S.M.A.R.T. Enable/Disable Attribute Autosave subcommand will not change the current Autosave status but the device will respond with the error code specified in “S.M.A.R.T. Error Codes” on Page 5.

The S.M.A.R.T. Disable Operations subcommand disables the autosave feature along with the device’s S.M.A.R.T. operations.

Upon the receipt of the subcommand from the host the device enables or disables the Autosave feature.

14.40.1.4S.M.A.R.T. Save Attribute Values (Subcommand D3h)

This subcommand causes the device to immediately save any updated Attribute Values to the device’s Attribute Data sector regardless of the state of the Attribute Autosave feature. Upon receipt of the S.M.A.R.T. Save Attribute Values subcommand from the host, the device writes any updated Attribute Values to the Attribute Data sector.

14.40.1.5S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h)

This subcommand causes the device to immediately initiate the set of activities that collect Attribute data in an off-line mode (off-line routine) or execute a self-test routine in either captive or off-line mode.

The LBA Low register shall be set to specify the operation to be executed.

HTS541640J9SA00, HTS541616J9SA00, HTS541680J9SA00, HTS541612J9SA00, HTS541660J9SA00 specifications

The Hitachi HTS541660J9SA00, HTS541640J9SA00, HTS541616J9SA00, HTS541680J9SA00, and HTS541612J9SA00 are a series of hard disk drives that showcase Hitachi's commitment to high-performance storage solutions. These drives belong to the Travelstar series, which is designed primarily for mobile computing applications, such as laptops and external storage devices. Their compact design and reliable performance make them suitable for users seeking efficient storage in portable settings.

One of the primary features of these drives is their SATA interface, which allows for fast data transfer rates, thereby enhancing overall system performance. The SATA II interface provides a maximum transfer rate of up to 3.0 Gbps, ensuring that these drives can keep up with the demands of modern computing.

The storage capacity of these models varies, with options such as 160GB, 250GB, and 320GB, catering to diverse user needs for both personal and professional use. The HTS541660J9SA00 provides a generous 160GB capacity, while the HTS541680J9SA00 offers up to 320GB, making them suitable for users who require significant storage space for media files, applications, and documents.

In terms of performance, these hard drives boast a rotational speed of 5400 RPM, striking an optimal balance between speed and energy efficiency. This speed ensures relatively quick access times while consuming less power compared to faster 7200 RPM drives, making them ideal for battery-powered devices.

Another significant characteristic of these drives is the use of Hitachi’s Advanced Format technology. This technology increases the physical sector size of the drives to 4KB, enhancing error correction and overall data integrity. This larger sector size allows for greater data efficiency, significantly reducing the overhead associated with data storage.

Furthermore, these drives are designed with Shock Protection technology, which helps to safeguard the drive's internal components from physical shocks caused by accidental drops or bumps. This feature is especially important for mobile storage solutions, where portability can lead to unintentional impacts.

In conclusion, the Hitachi HTS541660J9SA00, HTS541640J9SA00, HTS541616J9SA00, HTS541680J9SA00, and HTS541612J9SA00 hard disk drives are exemplary choices for anyone seeking reliable, efficient, and portable storage solutions. With their combination of adequate capacity, enhanced data management technologies, and robust design, these drives effectively meet the demands of today’s mobile computing needs.
