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. The export or re-export of hardware or software containing encryption may be regulated by the U.S. Department of Commerce, Bureau of Industry and Security (for more information, visit www.bis.doc.gov), and controlled for import and use outside of the U.S. Seagate reserves the right to change, without notice, product offerings or specifications.

This manual describes the functional, mechanical and interface specifications for the following Seagate® Laptop Thin HDD model drives:
Standard models |
Self-Encryption models |
SED FIPS 140-2 models |
|
|
|
ST500LM021 - 1KJ152 |
ST500LM023 - 1RR152 |
ST500LM024 - 1RS152 |

Previous generations of Seagate Self-Encrypting Drive models were called Note Full Disk Encryption (FDE) models before a differentiation between drive-
based encryption and other forms of encryption was necessary.
For more information on SED drives see About (SED) Self-Encrypting Drives on page 22.
For more information on FIPS 140-2 Level 2 certification see About FIPS on page 21.
These drives provide the following key features:
•1000 Gs nonoperating shock and 400 Gs of operating shock.
•16MB buffer.
•5400-RPM spindle speed.
•Full-track multiple-sector transfer capability without local processor intervention.
•High instantaneous (burst) data-transfer rates (up to 6Gb/s).
•Native Command Queuing (NCQ) with command ordering.
•Perpendicular recording technology.
•Quiet operation. Fluid Dynamic Bearing (FDB) motor.
•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 Read Multiple and Write Multiple commands.
•Support for S.M.A.R.T. drive monitoring and reporting.
•The 3D Defense System™, which includes Drive Defense, Data Defense and Diagnostic Defense, offers the industry’s most comprehensive protection for disk drives.
•Worldwide Name (WWN) capability uniquely identifies the drive.
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 are represented to host software as a Device 0 (master) and Device 1 (slave) accessed at Note 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, 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 3.2). The specification can be downloaded from www.serialata.org.

Rated workload |
Average rate of <55TB/year. The MTBF specification for the drive assumes the I/O workload does |
||
|
not exceed the average annualized workload rate limit of 55TB/year. Workloads exceeding the |
||
|
annualized rate may degrade the drive MTBF and impact product reliability. The average annual- |
||
|
ized workload rate limit is in units of TB per year, or TB per 8760 power-on hours. Workload rate |
||
|
limit = TB transferred × (8760/recorded power-on hours). |

Drive Specifications
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.

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, Note 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.

The drive receives DC power (+5V) through a native SATA power connector (refer to Figure 2).
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 HIPM 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 mode 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.
