Drive specifications:
Unless otherwise stated, all specifications are measured
under ambient conditions, 25°C, and nominal power. For suitability, the terms
drive and this drive are used in this physical to refer to the Seagate Skyhawk Surveillance AI
serial ATA drive model.
Compared with the traditional (parallel) ATA interface, the
serial ATA interface has several advantages. The main advantages include: Easy to install and configure, true plug-and-play connection. No need to set
any jumpers or other configuration options. Thinner and more flexible wiring,
which can improve the airflow of the cabinet and is easy to install.

Scalable to higher performance levels. In addition, Serial
ATA makes it easy to convert from Parallel ATA by providing traditional
software support. Serial ATA is intended to allow users to install Serial ATA
host connectors and Serial ATA disk drives in their current systems and expect
all existing requests to work properly. The Serial ATA interface connects each
disk drive to the Serial ATA host adapter in a point-to-point configuration.
Serial ATA devices do not have a master/slave relationship like parallel ATA.
If two drives are connected to a serial ATA host adapter, the host operating
system will treat the two devices as "master devices" on two separate
ports. This essentially means that the two drives behave as if they are device
0 (primary) devices.
Serial ATA host devices and drives share the ability to
simulate the conduct of parallel ATA devices to deliver backward compatibility with
existing host systems and software. Knowledge and control block registers, PIO
and DMA data transmission reset, and interrupts are all replicated.
Extended power supply conditions:
Utilize load/unload architecture to provide a programmable
power management interface to customize the system to reduce power consumption
and performance requirements. The following table lists the supported power
conditions available in Power Choice. Power conditions are sorted from highest
power consumption (and shortest recovery time) to lowest power consumption.
Each power disorder has a set of current, saved, and default
locations. The default settings cannot be modified. The default settings and
saved settings remain unchanged after the power-on reset. The current settings
will not remain untouched after the power-on reset. At the time of
manufacturing, the default saved and current settings are matched in the power
condition log.
Use one of the following two methods to
call Power Choice:
• Automatic power conversion is triggered by the expiration
of various power condition timers. You can use the Extended Power Condition
(EPC) the feature set to customize and enable these timer values using a
standardized setting function command interface.
• You can use the EPC setting function "Go to Power
Condition" sub-command to initiate an instant power conversion commanded
by the host to enter any supported power condition. The old-style power instructions
Standby Instant and Idle Instant also provide a way to directly convert the
drive to an armor-plated power disorder.
Drive installation:
The user can install the drive in any direction using the
four screws in the side mounting holes or the four screws in the bottom
mounting holes. Refer to Figure 3 for drive installation dimensions. When
installing the drive, please observe the following important installation
precautions:
• Leave a minimum clearance of 0.030 inches (0.76 mm) around the entire periphery of the drive for cooling.

• Use only 6-32 UNC mounting screws the screw should be
inserted into the bottom or side mounting hole to a depth no more than 0.140
inches (3.56 mm).
• Do not overtighten the mounting screws (maximum torque: 6-inch
pounds)
Test for prominent discrete tones:
Seagate follows the ECMA-74 standard to measure and identify
PDT. An exception to this process is the use of absolute hearing thresholds.
Seagate uses this inception curve (derived from ISO 389-7) to identify pitch
audibility and compensate for the inaudible mechanisms of the sound before
calculating the pitch ratio according to Annex D of the ECMA-74 normal.
The serial ATA interface cable involves four wires in two
differential pairs and three ground influences. The cable size maybe 30 to 26
AWG and the maximum length is 1 meter (39.37 inches).
