Introduction ® This manual describes the functional, mechanical and interface specifications for the following DiamondMax 20 Serial ATA model drives: STM3160811AS STM380811AS STM340211AS STM3160211AS STM380211AS These drives provide the following key features: • 7,200 RPM spindle speed. • High instantaneous (burst) data-transfer rates (up to 300 Mbytes per second). •...
About the Serial ATA interface The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include: • Easy installation and configuration with true plug-and-play connectivity. • Thinner and more flexible cabling for improved enclosure airflow and ease of installation. •...
Drive specifications Unless otherwise noted, all specifications are measured under ambient conditions, at 25°C, and nominal power. For convenience, the phrases the drive and this drive are used throughout this manual to indicate the following drive models: STM3160811AS STM380811AS STM340211AS STM3160211AS STM380211AS Specification summary tables...
Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows: • Track-to-track seek time is an average of all possible single-track seeks in both directions. •...
Power specifications The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 22. 2.8.1 Power consumption Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.
2.8.1.1 Typical current profiles Figure 1. Typical 5V startup and operation current profile Figure 2. Typical 12V startup and operation current profile 2.8.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line.
2.8.4 Power-management modes The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control power management through the system setup program. The drive features the following power-management modes: Power modes Heads Spindle Buffer Active Tracking Rotating Enabled...
Environmental specifications 2.9.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions for standard models, or 64°C (147°F) within the operating ambient conditions for all models. Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).
2.9.6 Vibration All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis. 2.9.6.1 Operating vibration The maximum vibration levels that the drive may experience while meeting the performance standards speci- fied in this document are specified below.
2.11 Electromagnetic immunity When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the radio frequency (RF) environments defined in the following table: Table 5: Radio frequency environments Test Description Performance level Reference standard Electrostatic...
2.13 Agency certification 2.13.1 Safety certification The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections of IEC950 and EN 60950 as tested by TUV North America. 2.13.2 Electromagnetic compatibility Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Elec- tromagnetic Compatibility Directive (89/336/EEC).
2.13.3 FCC verification These drives are intended to be contained solely within a personal computer or similar enclosure (not attached as an external device). As such, each drive is considered to be a subassembly even when it is individually mar- keted to the customer.
2.15 Corrosive environment Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment. Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation environment.

Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic dis- charge (ESD) hazards. Observe the following standard handling and static-discharge precautions: Caution: •...
Configuring the drive Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationship. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters”...
Drive mounting You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 5 for drive mounting dimensions. Follow these important mounting precau- tions when mounting the drive: •...

Advanced Power Management (APM) and Automatic Acoustic Management (AAM) features are not supported Note. See the bit descriptions below for words 63, 88, and 93 of the Identify Drive data. Description (if bit is set to 1) Word 63 Multiword DMA mode 0 is supported.
4.3.2 Set Features command This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an inter- rupt. If the value in the register does not represent a feature that the drive supports, the command is aborted. Power-on default has the read look-ahead and write caching features enabled.
4.3.3 S.M.A.R.T. commands S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive moni- tors predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T.
