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.
