www.seagate.com Drive Specifications 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 7: Table 7 Radio frequency environments Test Description Performance level Reference standard Electrostatic discharge Contact, HCP, VCP: ± 4 kV; Air: ± 8 kV B Radiated RF immunity 80MHz to 1,000MHz, 3 V/m, A 80% AM with 1kHz sine 900MHz, 3 V/m, 50% pulse modulation @ 200Hz Electrical fast transient ± 1 kV on AC mains, ± 0.5 kV on external I/O B EN61000-4-2: 95 EN61000-4-3: 96 ENV50204: 95 EN61000-4-4: 95 Surge immunity Conducted RF immunity ± 1 kV differential, ± 2 kV common, B AC mains 150kHz to 80MHz, 3 Vrms, 80% AM with A 1kHz sine EN61000-4-5: 95 EN61000-4-6: 97 Voltage dips, interrupts 0% open, 5 seconds 0% short, 5 seconds 40%, 0.10 seconds 70%, 0.01 seconds C EN61000-4-11: 94 C C B 2.12 Reliability The product shall achieve an Annualized Failure Rate (AFR) of 0.34% (MTBF of 0.75 million hours) when operated in an environment of ambient air temperatures of 25°C. Operation at temperatures outside the specifications in Section 2.9 may increase the product AFR (decrease MTBF). AFR and MTBF are population statistics that are not relevant to individual units. AFR and MTBF specifications are based on the following assumptions for desktop personal computer environments: • 2400 power-on-hours per year. • 10,000 average motor start/stop cycles per year. • Operations at nominal voltages. • Temperatures outside the specifications in Section 2.9 may reduce the product reliability. • Normal I/O duty cycle for desktop personal computers. Operation at excessive I/O duty cycle may degrade product reliability. The desktop personal computer environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR and MTBF. The AFR and MTBF will be degraded if used in an enterprise application Nonrecoverable read errors Annualized Failure Rate (AFR) Contact start-stop cycles Preventive maintenance 1 per 1014 bits read, max 0.34% (nominal power, 25°C ambient temperature) 50,000 cycles (at nominal voltage and temperature, with 60 cycles per hour and a 50% duty cycle) None required.
