Medalist 8641, 6531, 4321, 3221 and 2110, Rev. B Read/Write power and current are measured with the heads on track, based on a 16-sector write followed by a 32-msec delay, then a 16-sector read followed by a 32-msec delay. Operating power and current are measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10 reads), and 20 percent drive inactive.
Medalist 8641, 6531, 4321, 3221 and 2110, Rev. B 1.7.1.1 Typical current profile Figure 1 shows a typical current profile Current (Amps) Time (seconds) Figure 1. Typical startup and operation current profile 1.7.2 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.
These drives provide programmable power management to provide greater energy efficiency. In most systems, you can control power management through the system setup program. These Seagate drives feature several power-management modes, which are summarized in the following table and described in more detail below:...
Medalist 8641, 6531, 4321, 3221 and 2110, Rev. B 1.8 Environmental tolerances 1.8.1 Ambient temperature Operating 5° to 55°C (41° to 131°F) Nonoperating –40° to 70°C (–40° to 158°F) Note. Above 1,000 feet (305 meters), the maximum temperature is der- ated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).
Medalist 8641, 6531, 4321, 3221 and 2110, Rev. B 1.8.5.1 Operating shock These drives comply with the performance levels specified in this docu- ment when subjected to a maximum operating shock of 15.0 Gs (based on half-sine shock pulses of 11 msec). Shocks are not to be repeated more than two times per second.
Medalist 8641, 6531, 4321, 3221 and 2110, Rev. B 1.9 Drive acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are generally consistent with ISO document 7779. Sound power measurements are taken under essentially free-field conditions over a reflecting plane.
Communications Commission verification or certification of the device is required. Seagate Technology, Inc. has tested this device in enclosures as de- scribed above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of the FCC rules.
