2.9.2 Humidity 2.9.2.1 Relative humidity Operating: Nonoperating: 5% to 90% noncondensing (30% per hour max) 5% to 95% noncondensing (30% per hour max) 2.9.3 Altitude Operating: Nonoperating: -60.96 m to 3,048 m (-200 ft. to 10,000+ ft.) -60.96 m to 12,192 m (-200 ft. to 40,000+ ft.) 2.9.4 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis. 2.9.4.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 70 Gs (read) and 40 Gs (write) based on half-sine shock pulses of 2ms. Shocks should not be repeated more than two times per second. 2.9.4.2 Nonoperating shock 1TB and 500GB models The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 350 Gs based on a nonrepetitive half-sine shock pulse of 2ms duration. 2TB models The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 300 Gs based on a nonrepetitive half-sine shock pulse of 2ms duration. 2.9.5 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. 2.9.5.1 Operating vibration The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below. 5-22 Hz 22-350 Hz 350-500 Hz 20 - 1500Hz *(RROV) 0.25 Gs 0.50 Gs 0.25 Gs 12.5 rads/s2 w/RVFF * Rotary Random Operating Vibration 2.9.5.2 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. 10-500 Hz 4.9 Grms ref Linear Random CONSTELLATION ES SERIAL ATA PRODUCT MANUAL, REV.
