Page 11: Media Description
Supported block sizes are 512 for 512 emulation drives and 4096 for 4096 native drives. 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. -

Page 13: General Performance Characteristics
An unexpected power loss event, spin up at cold or hot temperature extremes may cause the drive to exceed the typical and max time to ready by 5 to 20 seconds. Extended time to ready is dependent on cache state and environmental conditions prior to the unexpected power loss and during the subsequent power on. Seagate Exos 2X18 SAS Product Manual, Rev.

Page 15: Caching Write Data
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. Seagate Exos 2X18 SAS Product Manual, Rev. A... -

The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage, and digital communications industry. Seagate’s SED models comply with the standards published by the TCG.

Page 33: Data Bands
In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files which have been cryptographically signed by the appropriate Seagate Design Center. Three conditions must be met before the drive will allow the download operation: The download must be an SED file. -
Page 34: Defect Error Management
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). In addition, Seagate provides the following technologies used to increase data integrity and drive reliability: •... -
Page 35: Sas System Errors
This is in contrast to the system having to use the Reassign Command to reassign a location that was unreadable and then generate a write command to rewrite the data. DAR is most effective when AWRE and ARRE are enabled—this is the default setting from the Seagate factory. With AWRE and ARRE disabled DAR is unable to reallocate the failing location and will report an error sense code indicating that a write command is being attempted to a previously failing location. -

The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the drive in horizontal (discs level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.
