SATA Interface
The Serial ATA (SATA) interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include:
- Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jumpers or other configuration options.
- Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
- Scalability to higher performance levels.
In addition, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was designed to allow users to install a SATA host adapter and SATA disk drive in the current system and expect all of the existing applications to work as normal.
The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is no master/slave relationship with SATA devices like there is with parallel ATA. If two drives are attached on one SATA host adapter, the host operating system views the two devices as if they were both "masters" on two separate ports. This essentially means both drives behave as if they are Device 0 (master) devices.
The SATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward compatibility with existing host systems and software. The Command and Control Block registers, PIO and DMA data transfers, resets, and interrupts are all emulated.
The SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA emulates parallel ATA, refer to the "Serial ATA International Organization: Serial ATA Revision 3.0". The specification can be downloaded from www.sata-io.org.
Hot-Plug Compatibility:
SkyHawk drives incorporate connectors which enable users to hot plug these drives in accordance with the SATA Revision 3.2 specification. This specification can be downloaded from www.serialata.org.

Table 6 summarizes the signals on the SATA interface and power connectors.

Power Specifications:
The drive receives DC power (+5V or +12V) through a native SATA power connector.
Power Consumption:
Power requirements are listed in tables for 8TB/6TB and 4TB/3TB/2TB models, detailing power dissipation in watts and typical amps for various states (Spinup, Idle, Operating, Standby, Sleep).
Conducted Noise:
Input noise ripple is measured at the host system power supply. Using 12-volt power, the drive expects a maximum of 120 mV peak-to-peak square-wave injected noise at up to 10MHz. Using 5-volt power, the drive expects a maximum of 100 mV peak-to-peak square-wave injected noise at up to 10MHz.
Voltage Tolerance:
Voltage tolerance (including noise) is ±5% for 5VDC and ±10% for 12VDC.
Power-Management Modes:
The drive provides programmable power management modes:
- Active mode: Drive is active during read/write and seek operations.
- Idle mode: Electronics remain powered; drive accepts commands and returns to Active mode when disk access is necessary.
- Standby mode: Drive enters Standby mode via command or inactivity timer. Electronics are in low power mode, heads are parked, spindle is at rest. Drive accepts commands and returns to Active mode when disk access is necessary.
- Sleep mode: Drive enters Sleep mode via command. Electronics are in low power mode, heads are parked, spindle is at rest. Drive exits Sleep mode upon Hard Reset or Soft Reset, entering Standby mode.
Environmental Specifications:
This section provides temperature, humidity, shock, and vibration specifications. Ambient temperature is the environment surrounding the drive. Temperature derates by 1°C per 1000 ft above 1000 ft.
- Ambient Temperature: Non-operating: -40° to 70°C; Operating ambient (min): 0°C; Operating (Drive case max): 70°C. (Sustained operation above 60°C is not recommended).
- Temperature gradient: 20°C per hour (operating, max), 30°C per hour (non-operating, max).
- Humidity: Operating: 5% to 90% non-condensing (30% per hour max); Non-operating: 5% to 95% non-condensing (30% per hour max).
- Wet bulb temperature: Operating: 30°C / 86°F (rated); Non-operating: 40°C / 104°F (rated).
- Altitude: Operating: -304m to 3048m (-1000 ft. to 10,000 ft.); Non-operating: -304m to 12,192m (-1000 ft. to 40,000+ ft.).
- Shock: Operating: 80 Gs (read) / 70 Gs (write) at 2ms (half-sine pulses); Non-operating: 300 Gs at 2ms (non-repetitive half-sine pulse).
- Vibration: Operating: 0.25 Gs (10-22Hz), 0.50 Gs (22-350Hz), 0.25 Gs (350-500Hz); Non-operating: 3.0 Gs (5-500Hz).
Acoustics:
Drive acoustics are measured as overall A-weighted sound power levels per ISO 7779. Idle acoustics are typically 2.6 bels, while seek acoustics are typically 2.7 bels.
Electromagnetic Immunity:
The drive operates without errors when subjected to specified RF environments, including electrostatic discharge, radiated RF immunity, electrical fast transient, surge immunity, conducted RF immunity, and voltage dips/interrupts, as defined by relevant standards (e.g., EN61000-4-x).
Configuring and Mounting the Drive
Handling and Static-Discharge Precautions:
Handle drives with care to prevent electrostatic discharge (ESD). Use a grounded wrist strap and touch grounded surfaces frequently. Handle drives by edges or frame only, avoid pressing the top cover, and rest on an antistatic surface.
Configuring the Drive:
SATA drives use a point-to-point connection, eliminating the need for master/slave configurations. If a "drive not detected" error occurs, the host adapter's chipset might not support SATA speed autonegotiation.
SATA Cables and Connectors:
The SATA interface cable consists of four conductors in two differential pairs plus ground connections. Cable size is 30 to 26 AWG with a maximum length of one meter. Drives support latching SATA connectors.
Drive Mounting:
Drives can be mounted in any orientation using four screws in side-mounting or bottom-mounting holes. Ensure a minimum clearance of 0.030 inches (0.76mm) for cooling. Use only 6-32 UNC mounting screws, inserted no more than 0.140 inch (3.56mm). Do not overtighten (max torque: 6 inch-lb).
SATA Interface Details
Hot-Plug Compatibility:
SkyHawk drives support hot-plugging in accordance with the SATA Revision 3.2 specification.
SATA Device Plug Connector Pin Definitions:
Table 6 details the signals on the SATA interface and power connectors, including ground, differential signal pairs (A, B), and power pins (3.3V, 5V, 12V).
Supported ATA Commands:
This section lists SATA standard commands supported by the drive, including their hexadecimal command codes. Key commands include Identify Device, Set Features, and S.M.A.R.T. commands.
Identify Device Command:
The Identify Device command (ECH) transfers drive information to the host, organized in a 512-byte block. This includes configuration, logical geometry, serial number, firmware revision, and model number.
Set Features Command:
This command controls various drive features, such as write cache, transfer modes (PIO, DMA, Ultra DMA), and power management settings.
S.M.A.R.T. Commands:
S.M.A.R.T. provides near-term failure prediction. The drive monitors attributes susceptible to degradation. If a failure is likely, S.M.A.R.T. reports status to the host. SeaTools diagnostic software includes a drive self-test (DST) command.
