1.8.6.1 Operating vibration
The following table lists the maximum vibration levels that the drive may expe- rience while meeting the performance standards specified in this document.
0.5 Gs acceleration (zero to peak) | |
0.25 Gs acceleration (zero to peak) |
1.8.6.2 Nonoperating vibration
The following table lists the maximum nonoperating vibration that the drive may experience without incurring physical damage or degradation in performance when subsequently put into operation.
5.0 Gs acceleration (zero to peak) | |
1.0 Gs acceleration (zero to peak) |
1.9 Drive acoustics
Drive acoustics are measured as overall
Note. For seek mode tests, the drive was 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)
Acoustic mode | Idle mode | Seek mode |
Sound power (bels) | 3.2 (typ) 3.6 (max) | 3.5 (typ) 3.9 (max) |
