Hitachi HTS543216L9A300 6.5.2Nonoperating vibration, 6.5.3Operating shock, Nonoperating shock

5K320 SATA OEM Specification

6.5.2Nonoperating vibration

The disk drive withstands the following vibration levels without any loss or permanent damage.

6.5.2.1Random vibration

The test consists of a random vibration applied in each of three mutually perpendicular axes for a duration of 15 minutes per axis. The PSD levels for the test simulating the shipping and relocation environment is shown below.

Hz	(m2/sec4)/Hz
2.5	0.096
5	2.88
40	1.73
500	1.73

Table 19. Random Vibration PSD Profile Breakpoints (nonoperating)

Note: Overall RMS level of vibration is 29.50 m/sec2 (3.01 G).

6.5.2.2Swept sine vibration

49 m/sec2 (5 G) (zero-to-peak), 10 to 500 to 10 Hz sine wave 0.5 oct/min sweep rate

25.4 mm (peak-to-peak) displacement, 5 to 10 to 5 Hz

6.5.3Operating shock

The hard disk drive meets the criteria in the table below while operating under these conditions: The shock test consists of 10 shock inputs in each axis and direction for a total of 60. There must be a minimum delay of 3 seconds between shock pulses.

The disk drive will operate without a hard error while subjected to the following half-sine shock pulse.

Duration of 1 ms	Duration of 2 ms
1960 m/sec2 (200 G)	3920 m/sec2 (400 G)

Table 20. Operating shock

The input level shall be applied to the normal disk drive subsystem mounting points used to secure the drive in a normal system.

6.5.4Nonoperating shock

The drive withstands the following half-sine shock pulse without any data loss or permanent damage.

Duration of 1 ms	Duration of 11 ms
9800 m/sec2 (1000 G)	1470 m/sec2 (150 G)

Table 21. Nonoperating shock

The shocks are applied for each direction of the drive for three mutually perpendicular axes, one axis at a time. Input levels are measured on a base plate where the drive is attached with four screws.
