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.

NOTE
NOTE
Previous generations of Seagate Self-Encrypting Drive models were called Full Disk Encryption (FDE)
models before a differentiation between drive-based encryption and other forms of encryption was necessary.
The Self-Encrypting Drive models indicated on the cover of this product manual have provisions for “Security of Data
at Rest” based on the standards defined by the Trusted Computing Group (see www.trustedcomputinggroup.org).
For more information on FIPS 140-2 Level 2 certification see About FIPS on page 17.
For more information on SED drives see
About (SED) Self-Encrypting Drives on page 18.
These drives provide the following key features:
5400-RPM spindle speed.
64MB buffer.
8GB NAND flash (ST500LX012, ST500LX013, ST500LX014 & ST500LX015 models)
16GB NAND flash (ST500LX009, ST500LX010, ST500LX011 & ST500LX016 models)
NOTE
Quiet operation. Fluid Dynamic Bearing (FDB) motor.
High instantaneous (burst) data-transfer rates (up to 6Gb/s).
Perpendicular recording technology.
State-of-the-art cache and on-the-fly error-correction algorithms.

offers the industry’s most comprehensive protection for disk drives.
Support for S.M.A.R.T. drive monitoring and reporting.
Support for Read Multiple and Write Multiple commands.
Worldwide Name (WWN) capability uniquely identifies the drive.
Seagate Ultra Mobile SSHD Self-Encrypting Drive models have the following additional features
Automatic data encryption/decryption
Controlled access

There is no significant performance difference between Self-Encrypting Drive and standard (non-Self-Encrypting Drive)
models.
SEAGATE ULTRA MOBILE SSHD PRODUCT MANUAL, REV. D 2
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 are represented to host software as a
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.
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 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.

does not exceed the average annualized workload rate limit of 55TB/year. Workloads exceed-
Rated workload
ing the annualized rate may degrade the drive MTBF and impact product reliability. The
average annualized 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).

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-track 1.5
Average 13.0
Average latency 5.6
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
NOTE
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
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.
Table 4. Typical power measurements are based on an average
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.

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 steady state (after 200ms from transition)
