The block size is selectable at format time. Supported block sizes are 512, 520, 524, and 528 for 512 emulation drives and 4096, 4160, 4192, and 4224 for 4096 native drives. Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed.
4.0 Performance characteristics This section provides detailed information concerning performance-related characteristics and features of Enterprise Capacity 3.5 HDD v7 drives. 4.1 Internal drive characteristics Drive capacity Read/write data heads Bytes/track Bytes/surface Tracks/surface (total) Tracks/in Peak bits/in Areal density Internal data rate Disk rotation speed Avg rotational latency 4.1.1 12TB models 16 2,265,088 714,500 395,250 392,000 2,283,000 923 2685 7200 4.
4.1.3 General performance characteristics Minimum sector interleave 1 to 1 Maximum Internal data rate* 2.7 Gb/s Sustained transfer rate 103 to 248 MiB/s ** SAS Interface maximum instantaneous transfer rate 1200MB/s* per port (dual port = 2400MB/s*) Logical block sizes 512 (default), 520, 524 or 528. 4096, 4160, 4192 or 4224.
4.4 Cache operation . Note Refer to the SAS Interface Manual for more detail concerning the cache bits. The buffer is divided into logical segments from which data is read and to which data is written. 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.
5.0 Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all interface timings, power supply voltages, environmental requirements and drive mounting constraints. Seek error rate: Read Error Rates1 Recovered Data Unrecovered Data Miscorrected Data Interface error rate: Mean Time Between Failure (MTBF): Annualized Failure Rate (AFR): Preventive maintenance: 1.
5.2 Reliability and service Users can enhance the reliability of Enterprise Capacity 3.5 HDD v7 disk 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 9.2 provides recommended air-flow information. 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.
5.2.3 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 users 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.
5.2.4 Thermal monitor Enterprise Capacity 3.5 HDD v7 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.
5.2.5.2 Implementation This section provides all of the information necessary to implement the DST function on this drive. 5.2.5.2.1 State of the drive prior to testing The drive must be in a ready state before issuing the Send Diagnostic command. There are multiple reasons why a drive may not be ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing a format, or another DST.
5.2.5.2.4 Log page entries When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a new self-test parameter block at the beginning of the self-test results log parameter section of the log page. Existing data will be moved to make room for the new parameter block. The drive reports 20 parameter blocks in the log page. If there are more than 20 parameter blocks, the least recent parameter block will be deleted.
6.0 Physical/electrical specifications This section provides information relating to the physical and electrical characteristics of the drive. 6.1 PowerChoiceTM power management Drives using the load/unload architecture provide programmable power management to tailor systems for performance and greater energy efficiency. The table below lists the supported PowerChoice modes. The further down the user goes in the table, the more power savings the user gets.
6.2 Power Balance • Mode page 01h byte 6 bits 0 & 1 define the Active Level • Active Levels - 00b Default,11b Lowest active power level 6.3 AC power requirements None. 6.4 DC power requirements The voltage and current requirements for a single drive are shown below. Values indicated apply at the drive connector.
[1] Measured with average reading DC ammeter. Instantaneous +12V current peaks will exceed these values. Power supply at nominal voltage. N (number of drives tested) = 6, 35 Degrees C ambient. For +12 V, a –10% tolerance is allowed during initial spindle start but must return to ± 10% before reaching 7200 RPM. The ± 10% must be maintained after the drive signifies that its power-up sequence has been completed and that the drive is able to accept selection by the host initiator.
6.4.3 Current profiles The +12V (top) and +5V (bottom) current profiles for the Enterprise Capacity 3.5 HDD drives are shown below. Figure 1. Note 12TB model current profiles. All times and currents are typical. See Table 3 for maximum current requirements. Seagate Enterprise Capacity 3.5 HDD v7 SAS Product Manual, Rev.
6.5 Power dissipation 12TB models in 12Gb operation Please refer to Table 3 for power dissipation numbers. To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 2.). Locate the typical I/O rate for a drive in the system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3.4123. Figure 2. 12TB models (12Gb) DC current and power vs.
6.6 Environmental limits Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C). Note 6.6.1 To maintain optimal performance drives should be run at nominal drive temperatures and humidity Temperature a.
6.6.4 Shock and vibration Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize drive movement.

7.0 About self-encrypting drives Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as “protection of data at rest.” These drives are compliant with the Trusted Computing Group (TCG) Enterprise Storage Specifications as detailed in Section 2.4. The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital communications industry.
7.5 Data bands When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data Band) which comprises LBA 0 through LBA max. The host may allocate Band1 by specifying a start LBA and an LBA range. The real estate for this band is taken from the Global Band.
8.0 Defect and error management Seagate continues to use innovative technologies to manage defects and errors. These technologies are designed to increase data integrity, perform drive self-maintenance, and validate proper drive operation. SCSI defect and error management involves drive internal defect/error management and SAS system error considerations (errors in communications between the initiator and the drive).

Valid range setting is 1-20. e.g.
8.6 Protection Information (PI) Protection Information is intended as a standardized approach to system level LRC traditionally provided by systems using 520 byte formatted LBAs. Drives formatted with PI information provide the same, common LBA count (i.e. same capacity point) as non-PI formatted drives. Sequential performance of a PI drive will be reduced by approximately 1.
9.0 Installation Enterprise Capacity 3.5 HDD v7 disk drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on the drive. SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to accommodate the drive. In such systems, the host system typically provides a carrier or tray into which users need to mount the drive.
9.2 Cooling Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding the drive will not exceed temperature conditions specified in Section 6.6.1, "Temperature." The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and head and disk assembly (HDA). Users should confirm that adequate heat removal is provided using the temperature measurement guidelines described in Section 6.6.1.
