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.

3.0General description

Seagate 1200 SSD drives provide high performance, high capacity data storage for a variety of systems with a Serial Attached SCSI (SAS) interface. The Serial Attached SCSI interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density storage requirements.

Seagate 1200 SSD 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. Seagate 1200 SSD 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 drives. This allows users to continue to leverage existing investment in SCSI while gaining a 12Gb/s serial data transfer rate.

[1] Warranty terms will vary based on type of warranty chosen: “Managed Life” or “Limited Warranty with Media Usage”. Consult the Seagate sales representative for warranty terms and conditions.

3.5Formatted capacities

Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time. Supported block sizes are 512, 520, 524, 528, 4096, 4160, 4192, and 4224. Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed.

To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends product planning in one of two modes:

Seagate designs specify 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 shown below. The Capacity stated is identical when the drive is formatted with or without PI enabled.

3.6Programmable 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.

3.7Factory-installed options

OEMs 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 LBA size requested and other factors.

•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.

3.8Thin Provisioning

3.8.1Logical Block Provisioning

The drive is designed with a feature called Thin Provisioning. Thin Provisioning is a technique which does not require Logical Blocks to be associated to Physical Blocks on the storage medium until such a time as needed. The use of Thin Provisioning is a major factor in SSD products because it reduces the amount of wear leveling and garbage collection that must be performed. The result is an increase in the products endurance. For more details on Logical Block Provisioning and Thin Provisioning, Reference the SBC-3 document provided by the T-10 committee.

3.8.2Thin Provisioning capabilities

The level of Thin Provisioning support may vary by product model. Devices that support Thin Provisioning are allowed to return a default data pattern for read requests made to Logical Blocks that have not been mapped to Physical Blocks by a previous WRITE command.

In order to determine if Thin Provisioning is supported and what features of it are implemented requires the system to send a READ CAPACITY 16 (9Eh) command to the drive. Thin Provisioning and the READ CAPACITY 16 (9Eh) command is defined in the Seagate SCSI Command Reference 100293068.

Product Configuration	LBPME	LBPRZ
Non-SED	Supported	Supported
SED	Supported	Not Supported

A logical block provisioning management enabled (LBPME) bit set to one indicates that the logical unit implements logical block provisioning management. An LBPME bit set to zero indicates that the logical unit is fully provisioned and does not implement logical block provisioning management.

A logical block provisioning read zeros (LBPRZ) bit set to one indicates that, for an unmapped LBA specified by a read operation, the device server sends user data with all bits set to zero to the data-in buffer. An LBPRZ bit set to zero indicates that, for an unmapped LBA specified by a read operation, the device server may send user data with all bits set to any value to the data-in buffer.

3.8.3UNMAP

The UNMAP command requests that the device server break the association of a specific Logical Block address from a Physical Block, thereby freeing up the Physical Block from use and no longer requiring it to contain user data. An unmapped block will respond to a READ command with data that is determined by the setting of the LBPRZ bit in the READ CAPACITY parameter data.

3.8.4FORMAT UNIT command

A device which supports Thin Provisioning will be capable of performing a SCSI FORMAT UNIT command which allocates Logical Blocks Addresses that are not linked to Physical Block Locations. A FORMAT command will cause all LBAs to become unmapped.

3.8.5Protection Information (PI) and Security (SED)

The requirements in this section apply to any device which supports LBA unmapping.

Seagate 1200 SSD Product Manual, Rev. C

13

In SCSI devices, umapped LBAs are defined as part of the Thin Provisioning model. Support of the Thin Provisioning model is indicated by the LBPME bit having a value of '1' in the READ CAPACITY (16) parameter data.

When a region of LBA's are erased via cryptographic erase, as part of the erase, the drive shall unmap those LBAs.

If the host attempts to access an unmapped or trimmed LBA, the drive shall return scrambled data. For a given LBA, the data shall be identical from access to access, until that LBA is either updated with actual data from the host or that LBA is cryptographically erased. The drive shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16) parameter data.

If the host attempts to access an unmapped LBA on a drive that has been formatted with Protection Information (PI), the drive shall return scrambled PI data for that LBA. Depending on the value of the RDPROTECT field in the data-access command CDB, this may result in the drive returning a standard PI error to the host.

If the host reduces the addressable capacity of the drive via a MODE SELECT command, the drive shall unmap or trim any LBA within the inaccessible region of the device.

Additionally, an UNMAP command is not permitted on a locked band.

Peak performance is defined as the typical best case performance that the product will be able to achieve when the product is preconditioned as mentioned and host commands are aligned on 4KB boundaries.

Sustained performance is defined as the worst case performance that the product will be able to achieve when the product is preconditioned as mentioned and host commands are aligned on 4KB boundaries. For models that support Lifetime Endurance Management, write values also take into account the worst case performance throttling that may occur to ensure the product meets specified reliability specifications.

Due to the nature of Flash memory technologies there are many factors that can result in values different than those stated in this specification. Some discrepancies can be caused by bandwidth limitations in the host adapter, operating system, or driver limitations. It is not the intent of this manual to cover all possible causes of performance discrepancies.

When evaluating performance of SSD devices, it is recommended to measure performance of the device in a method that resembles the targeted application using real world data and workloads. Test time should also be adequately large to ensure that sustainable metrics and measures are obtained.

4.3Start/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 START STOP UNIT command with the START bit equal to 0, the drive becomes ready for normal operations within 10 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 START STOP 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 waits for a NOTIFY (ENABLE SPINUP) primitive. After receiving a NOTIFY (ENABLE SPINUP) primitive through either port, the drive becomes ready for normal operations within 10 seconds (excluding the error recovery procedure).

If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does not receive a NOTIFY (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. Stop time is 3 seconds (maximum) from removal of DC power. SCSI stop time is 3 seconds. There is no power control switch on the drive.

4.4Cache control

All default cache mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in Section 11.3.2.

4.4.1Caching write data

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 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.

Data that has not been written to the medium is protected by a back up power source which provides the ability of the data to be written to non-volatile medium in the event of an unexpected power loss.

The SYNCHRONIZE CACHE command may be used to force the drive to write all cached write data to the medium. Upon completion of a SYNCHRONIZE CACHE command, all data received from previous WRITE commands will have been written to the medium. Section 11.3.2 shows the mode default settings for the drive.

4.4.2Prefetch operation

If the Prefetch feature is enabled, data in contiguous logical blocks on the medium 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 medium 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.

1.Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated.

2.As NAND Flash devices age with use, the capability of the media to retain a programmed value begins to deteriorate. This deterioration is affected by the number of times a particular memory cell is programmed and subsequently erased. When a device is new, it has a powered off data retention capability of up to several years. With use the retention capability of the device is reduced. Temperature also has an effect on how long a Flash component can retain its programmed value with power removed. At high temperature the retention capabilities of the device are reduced. Data retention is not an issue with power applied to the SSD. The SSD drive contains firmware and hardware features that can monitor and refresh memory cells when power is applied.

3.Endurance rating is the expected amount of host data that can be written by product when subjected to a specified work-

load at a specified operating and storage temperature over the specified product life. For the specific workload to achieve this level of endurance, please reference JEDEC Specification JESD218. TBW is defined as 1x1012 Bytes.

4.Limited Warranty with Media Usage provides coverage for the warranty period or until the SSD Percentage Used Endurance Indicator, as defined in Section 5.2.7, reaches 100 whichever comes first.

Seagate 1200 SSD Product Manual, Rev. C

5.1Error rates

The error rates stated in this manual assume the following:

•The drive is operated in accordance with this manual using DC power as defined in paragraph 6.3, "DC power requirements."

•Errors caused by host system failures are excluded from error rate computations.

•Assume random data.

•Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry time.

5.1.1Unrecoverable Errors

An unrecoverable data error is defined as a failure of the drive to recover data from the media. These errors occur due to read 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.

5.1.2Interface 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.

5.2Endurance Management

Customer satisfaction with Solid State Drives can be directly related to the internal algorithms which an SSD uses to manage the limited number of Program-Erase (PE) cycles that NAND Flash can withstand. These algorithms consist of Wearleveling, Garbage Collection, Write Amplification, Unmap, Data Retention, Lifetime Endurance Management.

5.2.1Wear Leveling

Wear Leveling is a technique used by the drive to ensure that all Flash cells are written to or exercised as evenly as possible to avoid any hot spots where some cells are used up faster than other locations. Wear Leveling is automatically managed by the drive and requires no user interaction. The Seagate algorithm is tuned to operate only when needed to ensure reliable product operation.

5.2.2Garbage Collection

Garbage Collection is a technique used by the drive to consolidate valid user data into a common cell range freeing up unused or obsolete locations to be erased and used for future storage needs. Garbage Collection is automatically managed by the drive and requires no user interaction. The Seagate algorithm is tuned to operate only when needed to ensure reliable product operation.

5.2.3Write Amplification

While Write Amplification is not an algorithm, it is a major characteristic of SSD's that must be accounted for by all the algorithms that the SSD implements. The Write Amplification Factor of an SSD is defined as the ratio of Host/User data requested to be written to the actual amount of data written by the SSD internal to account for the user data and the housekeeping activities such as Wear Leveling and Garbage Collection. The Write Amplification Factor of an SSD can also be directly affected by the characteristics of the host data being sent to the SSD to write. The best Write Amplification Factor is achieved for data that is written in sequential LBA's that are aligned on 4KB boundaries. The worst case Write Amplification Factor typically occurs for randomly written LBA's of transfer sizes that are less than 4KB and that originate on LBA's that are not on 4KB boundaries.

5.2.4UNMAP

A new SCSI command has been added to the SSD as part of the Thin Provisioning feature set. Use of the UNMAP command reduces the Write Amplification Factor of the drive during housekeeping tasks such as Wear Leveling and Garbage Collection. This is accomplished because the drive does not need to retain data which has been classified by the host as obsolete.

Seagate 1200 SSD Product Manual, Rev. C

21

5.2.5Data Retention

Data Retention is another major characteristic of SSD's that must be accounted for by all the algorithms that the SSD implements. While powered up, the Data Retention of SSD cells are monitored and rewritten if the cell levels decay to an unexpected level. Data Retention when the drive is powered off is affected by Program and Erase (PE) cycles and the temperature of the drive when stored.

5.2.6Lifetime Endurance Management (Available on select models)

As stated in Section 5.2, an SSD has a limited number of Program and Erase (PE) cycles that are capable. In worse case applications, the write workload could be such that the drive experiences a high Write Amplification Factor that could lead to potential wear out prior to the drive achieving it's expected field life. Additionally, the Data Retention spec of the SSD needs to be considered to ensure the spec is met once the drive is worn out. Seagate has implemented a Lifetime Endurance Management technique which helps OEMS and user to avoid early wear out. By monitoring the write workload being sent to the drive, the drive can add additional response time to WRITE commands to provide a sustainable level of performance that is capable of being sustained for the life of the drive. Most users may never see this added response time in their applications.

5.2.7SSD Percentage Used Endurance Indicator

An application can interrogate the drive through the host to determine an estimate of the percentage of device life that has been used. To accomplish this, issue a LOG SENSE command to log page 0x11. This allows applications to read the contents of the Percentage Used Endurance Indicator parameter code. The Percentage Used Endurance Indicator is defined in the T10 document SBC-3 available from the T10 committee.

5.3Reliability and service

Integrators can enhance the reliability of Seagate 1200 SSD drives 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.

5.3.1Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF)

The production drive shall achieve an AFR of 0.44% (MTBF of 2,000,000 hours) when operated in an environment that ensures the case temperatures do not exceed the values specified in Section 6.5. Operation at case temperatures outside the specifications in Section 6.5 may increase the product AFR (decrease the MTBF). The AFR (MTBF) is a population statistic not relevant to individual units.

The AFR (MTBF) specification is based on the following assumptions for Enterprise Storage System environments:

•8760 power-on hours per year.

•250 average on/off cycles per year.

•Operations at nominal voltages.

•Systems will provide adequate cooling to ensure the case temperatures specified in Section 6.5 are not exceeded. Temperatures outside the specifications in Section 6.5 will increase the product AFR and decrease the MTBF.

5.3.2Preventive maintenance

No routine scheduled preventive maintenance is required.

5.3.3Hot plugging the drive

When a drive is powered on by switching the power or hot plugged, the drive runs a self test before attempting to communicate on its’ interfaces. When the self test completes successfully, the drive initiates a Link Reset starting with OOB. An attached device should 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, 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.

Seagate 1200 SSD Product Manual, Rev. C

5.3.4S.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 administrators 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.

An application 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.

An application 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 REZERO UNIT command resets the timer.

Performance impact

S.M.A.R.T. attribute data is saved to the media 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 media is interruptible. The maximum on-line only processing delay is summarized below

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. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors increases to 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 appropriate 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 be acceptable. In either case, the interval and failure counters are reset and the process starts over.
