6.5.4.2
Vibration
a. Operating—normal
The drive as installed for normal operation, shall comply with the complete specified performance while subjected to continuous
vibration not exceeding
5-500 Hz @ 0.5 G (zero to peak)
Vibration may be applied in the X, Y, or Z axis.
Operating normal translational random flat profile
10 - 500 Hz (translational random flat profile)
0.5 GRMS
b. Non-operating
The limits of non-operating vibration shall apply to all conditions of handling and transportation. This includes both isolated
drives and integrated drives.
The drive shall not incur physical damage or degraded performance as a result of continuous vibration not exceeding
5-500 Hz @ 3.0 G (zero to peak)
Vibration may be applied in the X, Y, or Z axis.
Non-operating translational random flat profile
10 - 500 Hz
(translational random flat profile)
2.4 GRMS
6.5.5
Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
6.5.6
Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial
environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing
cannot duplicate every potential application environment.
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as
electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used
in hard disk drives are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the
most damaging. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be
minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with
sulfide-free alternatives.
Seagate recommends that data centers be kept clean by monitoring and controlling the dust and gaseous contamination. Gaseous
contamination should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured on copper and silver coupons), and dust
contamination to ISO 14644-1 Class 8 standards, and MTBF rated conditions as defined in the Annualized Failure Rate (AFR) and
Mean Time Between Failure (MTBF) section.
6.5.7
Acoustics
Sound power during idle mode shall be 3.1 bels typical when measured to ISO 7779 specification.
There will not be any discrete tones more than 9 dB above the masking noise on typical drives when measured according to Seagate
specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.
6.5.8
Electromagnetic susceptibility
See Section 2.1.1.1.
