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.

3.0 General description
These drives provide high performance, high capacity data storage for a variety of systems including engineering workstations, network
servers, mainframes, and supercomputers. The Serial Attached SCSI interface is designed to meet next-generation computing demands
for performance, scalability, flexibility and high-density storage requirements.
The hybrid functionality of the 15K drive provides improved performance over standard HDDs in real-world workloads. This improvement is
due to the addition of a solid state component that caches “hot” data for reads as well as protects write data via non-volatile cache (NVC).
These drives are random access storage devices designed to support the Serial Attached SCSI Protocol as described in the ANSI
specifications, this document, and the SAS Interface Manual (part number 100293071) which describes the general interface
characteristics of this drive. These drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the
ANSI SCSI-1 standard. The SAS connectors, cables and electrical interface are compatible with Serial ATA (SATA), giving future users the
choice of populating their systems with either SAS or SATA hard disk drives. This allows integrators to continue to leverage existing
investment in SCSI while gaining a 12.0Gb/s serial data transfer rate.
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
The head and disk assembly (HDA) is sealed at the factory. Air recirculates within the HDA through a non-replaceable filter to maintain a
contamination-free HDA environment.
Note. Never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads, media, actuator, etc.) as this
requires special facilities. The drive does not contain user-replaceable parts. Opening the HDA for any reason voids the
warranty.
www.trustedcomputinggroup.org).
Savvio drives use a dedicated landing zone at the innermost radius of the media to eliminate the possibility of destroying or degrading data
by landing in the data zone. The heads automatically go to the landing zone when power is removed from the drive.
An automatic shipping lock prevents potential damage to the heads and discs that results from movement during shipping and handling.
The shipping lock disengages and the head load process begins when power is applied to the drive.
These drives decode track 0 location data from the servo data embedded on each surface to eliminate mechanical transducer adjustments
and related reliability concerns.
The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design that provides
excellent performance with minimal power dissipation.

To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate rec ommends
product planning in one of two modes:
Seagate designs capacity points at certain block sizes that Seagate guarantees current and future products will meet. We recommend
customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward compatibility from
generation to generation. The current guaranteed operating points for this product are:

3.6 Programmable drive capacity
Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select (6) parameter
list table in the SAS Interface Manual, part number 100293071. A value of zero in the Number of Blocks field indicates that the drive will not
change the capacity it is currently formatted to have. A number other than zero and less than the maximum number of LBAs in the Number
of Blocks field changes the total drive capacity to the value in the Number of Blocks field. A value greater than the maximum number of
LBAs is rounded down to the maximum capacity.
3.7 Factory installed options
Integrators may order the following items which are incorporated at the manufacturing facility during production or packaged before
shipping. Some of the options available are (not an exhaustive list of possible options):
• Other capacities can be ordered depending on sparing scheme and sector size requested.
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit damage. Units
shipped individually require additional protection as provided by the single unit shipping pack. Users planning single unit distribution
should specify this option.
• The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM drive shipped,
but extra copies may be ordered.

4.3 Start/stop time
The drive accepts the commands listed in the SAS Interface Manual less than 3 seconds after DC power has been applied.
If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a ST AR T STOP UNIT command with
the START bit equal to 0, the drive becomes ready for normal operations within 20 seconds (excluding the error recovery procedure).
If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE SPINUP)
primitive, the drive waits for a ST ART ST OP UNIT command with the START bit equal to 1. After receiving a START STOP UNIT command
with the START bit equal to 1, the drive wa its for a NOTIFY (ENABLE SPINUP) primitive. After receiving a NOTIFY (ENABLE SPINUP)
primitive through either port, the drive becomes ready for normal operations within 20 seconds (excluding the error recovery procedure).
If the d rive r ece ive s a START STOP UN IT com man d wit h the START bi t and IM MED b it eq ual to 1 a nd do es not r ece ive a N OTIF Y
(ENABLE SPINUP) primitive within 5 seconds, the drive fails the START STOP UNIT command.
The START STOP UNIT command may be used to command the drive to stop the spindle. Stop time is 20 seconds (maximum) from
removal of DC power. SCSI stop time is 20 seconds. There is no power control switch on the drive.
4.4 Prefetch/multi-segmented cache control
The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system
performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the host sends the
Mode Select command with the proper values in the applicable bytes in page 08h. Prefetch and cache operations are independent
features from the standpoint that each is enabled and disabled independently using the Mode Select command; however, in actual
operation, the prefetch feature overlaps cache operation somewhat as described in sections 4.5.1 and 4.5.2.
All default cache and prefetch mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in Table
10 for 300GB, Table 11 for 450GB and Table 12 for 600GB.
4.5 Cache operation
Note. Refer to the SAS Interface Manual for more detail concerning the cache bits.
Of the 128MB physical buffer space in the drive, approximately 60,000KB are available as a data cache. The remaining buffer space is
reserved for internal drive use.
The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled (see RCD bit
in the SAS Interface Manual ), data requested by the host with a read command is retrieved from the buffer, if possible, before any disk
access is initiated. If cache operation is not enabled, the buffer is still used, but only as circular buffer segments during disk medium read
operations (disregarding Prefetch operation for the moment). That is, the drive does not check in the buffer segments for the requested
read data, but goes directly to the medium to retrieve it. The retrieved data merely passes through some buffer segment on the way to the
host. All data transfers to the host are in accordance with buffer-full ratio rules. See the explanation provided with the information about
Mode Page 02h (disconnect/reconnect control) in the SAS Interface Manual.
The following is a simplified description of the prefetch/cache operation:
Case A—read command is received and all of the requested logical blocks are already in the cache:
1. Drive transfers the requested logical blocks to the initiator.
Case B—A Read command requests data, and at least one requested logical block is not in any segment of the cache:
1. The drive fetches the requested logical blocks from the disk and transfers them into a segment, and then from there to the host in
accordance with the Mode Select Disconnect/Reconnect parameters, page 02h.
2. If the prefetch feature is enabled, refer to section 4.5.2 for operation from this point.
Each cache segment is actually a self-contained circular buffer whose length is an integer number of logical blocks. The drive dynamically
creates and removes segments based on the workload. The wrap-around capability of the individual segments greatly enhances the
cache’s overall performance.
Note. The size of each segment is not reported by Mode Sense command page 08h, bytes 14 and 15. The value 0XFFFF is always
reported regardless of the actual size of the segment. Sending a size specification using the Mode Select command (bytes 14
and 15) does not set up a new segment size. If the STRICT bit in Mode page 00h (byte 2, bit 1) is set to one, the drive
responds as it does for any attempt to change an unchangeable parameter.

4.5.1 Caching write data
Note. Write caching in this section is the traditional SCSI write caching (WCE=1) where writes are not protected on power loss.
Hybrid provides NVC-protected write caching when WCE=0 over a portion of the DRAM.
Note. Refer to the SAS Interface Manual for more detail concerning the cache bits.”
Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to be written to the medium is
stored while the drive performs the Write command.
If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made available for future read cache
hits. The same buffer space and segmentation is used as set up for read functions. The buffer segmentation scheme is set up or changed
independently , having nothing to do with the state of RCD. When a write command is issued, if RCD=0, the cache is first checked to see if
any logical blocks that are to be written are already stored in the cache from a previous read or write command. If there are, the respective
cache segments are cleared. The new data is cached for subsequent Read commands.
If the number of write data logical blocks exceed the size of the segment being written into, when the end of the segment is reached, the
data is written into the beginning of the same cache segment, overwriting the data that was written there at the beginning of the operation;
however, the drive does not overwrite data that has not yet been written to the medium.
If write caching is enabled (WCE=1), then the drive may return Good status on a write command after the data has been transferred into
the cache, but before the data has been written to the medium. If an error occurs while writing the data to the medium, and Good status
has already been returned, a deferred error will be generated.
The Synch roni ze Cac he comm and ma y be use d to forc e the dr ive to w rite a ll cach ed wri te data t o the me dium . Upon c omple tion o f a
Synchronize Cache command, all data received from previous write commands will have been written to the medium.
in Table 10 for 300GB, Table 11 for 450GB and Table 12 for 600GB shows the mode default settings.
4.5.2 Prefetch operation
If the Prefetch feature is enabled, data in contiguous logical blocks on the disk immediately beyond that which was requested by a Read
command are retrieved and stored in the buffer for immediate transfer from the buffer to the host on subsequent Read commands that
request those logical blocks (this is true even if cache operation is disabled). Though the prefetch operation uses the buffer as a cache,
finding the requested data in the buffer is a prefetch hit, not a cache operation hit.
To enable prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0 enables prefetch.
The drive does not use the Max Prefetch field (bytes 8 and 9) or the Prefetch Ceiling field (bytes 10 and 11).
When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous blocks from the disk when it
senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is not likely to occur.
4.5.3 Hybrid caching operations
Hybrid caching operation Read data that has been promoted into the hybrid read cache does not persist through a power cycle. The read
data can always be retrieved from the rotating media.
When WCE=0, Hybrid 10K provides NVC-protected write caching over the portion of the DRAM used to coalesce writes. Write data only
goes into NVC when there is an unexpected power loss to the drive. The NVC has 90-day data retention.
If WCE=1, then a hybrid drive will operate on writes like a standard HDD–writes in cache are not protected by NVC and may be lost with
power loss.”

5.1.1 Recoverable Errors
Recoverable errors are those detected and corrected by the drive, and do not require user intervention.
Recoverable Data errors will use Error Correction when needed.
Recovered Data e rror rat e is deter mined usi ng read bi ts trans ferred f or recove rable er rors occ urring d uring a rea d, and usi ng write bits

5.1.2 Unrecoverable Errors
An unrecoverable data error is defined as a failure of the drive to recover data from the media. These errors occur due to head/media or
write problems. Unrecoverable data errors are only detected during read operations, but not caused by the read. If an unrecoverable data
error is detected, a MEDIUM ERROR (03h) in the Sense Key will be reported. Multiple unrecoverable data errors resulting from the same
cause are treated as 1 error.
5.1.3 Seek errors
A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive
automatically performs an error recovery process. If the error recovery process fails, a seek positioning error (Error code = 15h or 02h) will
be reported with a Hardware error (04h) in the Sense Key. Recoverable seek errors are specified at Less than 10 errors in 10
Unrecoverable seek errors (Sense Key = 04h) are classified as drive failures.
5.1.4 Interface errors
An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port connected to the
receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC error.

5.2 Reliability and service
Integrators can enhance the reliability of Enterprise Performance 15K HDD and Enterprise Turbo SSHD disk drives can be enhanced
by ensuring that the drive receives adequate cooling. Section 6.0 provides temperature measurements and other information
that may be used to enhance the service life of the drive. Section 10.2 provides recommended air-flow information.
SEAGATE ENTERPRISE PERFORMANCE 15K HDD V5 AND TURBO SSHD V2 PRODUCT MANUAL, REV. B 12
5.2.1 Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF)
The production disk drive shall achieve an annualized failure-rate of 0.44% (MTBF of 2,000,000 hours) over a 5 year service life when
used in Enterprise Storage field conditions as limited by the following:
• 8760 power-on hours per year.
• HDA temperature as reported by the drive <= 50C
• Ambient wet bulb temp <= 26°C
• The AFR (MTBF) is a population statistic not relevant to individual units.
• ANSI/ISA S71.04-2013 G2 classification levels and dust contamination to ISO 14644-1 Class 8 standards (as measured at the device)
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal drive temperature and humidity.
The rated MTBF is based upon a sustained drive temperature of up to 122°F (50°C) and wet bulb temperature up to 78.8°F (26°C).
Occasional excursions in operating conditions between the rated MTBF conditions and the maximum drive operating conditions may occur
without significant impact to the rated MTBF. However continual or sustained operation beyond the rated MTBF conditions will degrade the
drive MTBF and reduce product reliability.
5.2.2 Preventive maintenance
No routine scheduled preventive maintenance is required.
5.2.3 Hot plugging the drive
When a disk is powered on by switching the power or hot plugged, the drive runs a self test before attempting to communicate on its’
inte rfac es. W hen t he sel f tes t comp let es su cces sfu lly, the dr ive in iti ate s a Link R ese t star tin g wit h OOB. An at tach ed de vice s hould
respond to the link reset. If the link reset attempt fails, or any time the drive looses sync, the drive initiated link reset. The drive will initiate
link reset once per second but alternates between port A and B. Therefore each port will attempt a link reset once per 2 seconds assuming
both ports are out of sync.
If the self-test fails, the drive does not respond to link reset on the failing port.
Note. It is the responsibility of the systems integrator to assure that no temperature, energy, voltage hazard, shorting of PCBA to
ground, or ESD potential hazard is presented during the hot connect/disconnect operation. Discharge the static electricity
from the drive carrier prior to inserting it into the system.
Caution. The drive motor must come to a complete stop prior to changing the plane of operation. This time is required to insure data
integrity.
5.2.4 S.M.A.R.T.
S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that
indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow an application to back up the data before an
actual failure occurs.
Note. The drive’s firmware monitors specific attributes for degradation over time but can’t predict instantaneous drive failures.
Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating performance of the drive and the
thresholds are optimized to minimize “false” and “failed” predictions.
Controlling S.M.A.R.T.
The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Informational Exceptions Control mode page (1Ch).
Use the DEXCPT bit to enable or disable the S.M.A.R.T. feature. Setting the DEXCPT bit disables all S.M.A.R.T. functions. When enabled,
S.M.A.R.T. collects on-line data as the drive performs normal read and write operations. When the PERF bit is set, the drive is considered
to be in “On-line Mode Only” and will not perform off-line functions.
Applications can measure off-line attributes and force the drive to save the data by using the Rezero Unit command. Forcing S.M.A.R.T.
resets the timer so that the next scheduled interrupt is in one hour.
Applications can interrogate the drive through the host to determine the time remaining before the next scheduled measurement and data
logging process occurs. To accomplish this, issue a Log Sense command to log page 0x3E. This allows applications to control when
S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the RTZ command resets the timer.
SEAGATE ENTERPRISE PERFORMANCE 15K HDD V5 AND TURBO SSHD V2 PRODUCT MANUAL, REV. B 13
Performance impact
S.M.A.R.T. attribute data is saved to the disk so that the events that caused a predictive failure can be recreated. The drive measures and
saves parameters once every hour subject to an idle period on the drive interfaces. The process of measuring off-line attribute data and
saving data to the disk is interruptable. The maximum on-line only processing delay is summarized below:
Maximum processing delay
Fully-enabled delay DEXCPT = 0
S.M.A.R.T. delay times 70 milliseconds
Reporting control
Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting method. For
example, if the MRIE is set to one, the firmware will issue to the host an 01-5D00 sense code. The FRU field contains the type of predictive
failure that occurred. The error code is preserved through bus resets and power cycles.
Determining rate
S.M .A. R. T. m oni to rs th e rat e at wh ich e rro rs oc cu r and s ign als a p red ict iv e fai lur e if th e rat e of de gr ade d err ors i ncr eas es t o an
unacceptable level. To determine rate, error events are logged and compared to the number of total operations for a given attribute. The
interval defines the number of operations over which to measure the rate. The counter that keeps track of the current number of operations
is referred to as the Interval Counter.
S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of errors for the
current interval. This counter is referred to as the Failure Counter.
Error rate is the number of errors per operation. The algorithm that S.M.A.R.T. uses to record rates of error is to set thresholds for the
number of errors and their interval. If the number of errors exceeds the threshold before the interval expires, the error rate is considered to
be unacceptable. If the number of errors does not exceed the threshold before the interval expires, the error rate is considered to b e
acceptable. In either case, the interval and failure counters are reset and the process starts over.
Predictive failures
S.M.A.R.T. signals predictive failures when the drive is performing unacceptably for a period of time. The firmware keeps a running count
of the number of times the error rate for each attribute is unacceptable. To accomplish this, a counter is incremented each time the error
rate is unacceptable and decremented (not to exceed zero) whenever the error rate is acceptable. If the counter continually increments
such that it reaches the predictive threshold, a predictive failure is signaled. This counter is referred to as the Failure History Counter.
There is a separate Failure History Counter for each attribute.
5.2.5 Thermal monitor
Enterprise Performance 15K HDD and Enterprise Turbo SSHD drives implement a temperature warning system which:
1. Signals the host if the temperature exceeds a value which would threaten the drive.
2. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.
A temperature sensor monitors the drive temperature and issues a warning over the interface when the temperature exceeds a set
threshold. The temperature is measured at power-up and then at ten-minute intervals after power-up.
The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the specified limit in compliance with
the SCSI standard.
This feature is controlled by the Enable Warning (EWasc) bit, and the reporting mechanism is controlled by the Method of Reporting
Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page (1Ch).
