C 2. 10 Acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). Sound power measurements are taken under essentially free-field conditions over a reflecting plane. 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. · Temperatures outside the specifications in Section 2. 9 may reduce the product reliability. 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.

C 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 interrupt. [. . . ]
