[. . . ] 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 specified in this document are specified below. 5­22 Hz 22­350 Hz 350­500 Hz 0. 25 Gs (Limited displacement) 0. 50 Gs 0. 25 Gs 2. 9. 6. 2 Nonoperating vibration The maximum nonoperating vibration levels that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation are specified below. 5­22 Hz 22­350 Hz 350­500 Hz 0. 25 Gs (limited displacement) 5. 0 Gs 1. 0 Gs 24 DiamondMax 21 Serial ATA Product Manual, Rev. C 2. 10 Acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are consistent with ISO document 7779. Sound power measurements are taken under essentially free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward. For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined by the following equation: (Number of seeks per second = 0. 4 / (average latency + average access time) Table 8: Fluid Dynamic Bearing (FDB) motor acoustics Idle* Seek 3. 7 bels (typ)** 3. 9 bels (max)** 3. 0 bels (typ)** 3. 2 bels (max)** 3. 4 bels (typ)** 3. 6 bels (max)** 2. 7 bels (typ)*** 2. 8 bels (max)*** 3. 0 bels (typ)*** 3. 2 bels (max)*** STM3500630AS STM3320620AS, STM3320820AS, and STM3250820AS STM3250824AS STM3250310AS STM3160815AS, STM3160215AS, STM380815AS STM380215AS and STM340215AS 2. 8 bels (typ) 3. 0 bels (max) 2. 5 bels (typ) 2. 9 bels (max) 2. 7 bels (typ) 2. 9 bels (max) 2. 6 bels (typ) 2. 7 bels (max) 2. 8 bels (typ) 3. 0 bels (max) *During periods of drive idle, some offline activity may occur according to the S.

C 25 2. 12 2. 12. 1 Reliability Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF) The product shall achieve an Annualized Failure Rate (AFR) of 0. 34% (MTBF of 0. 7 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 a enterprise application.
