Table 4 System Environmental Limits Summary
Limits
-40º C to 70º C (-40º F to 158º F)
50% to 90%, non-condensing with a maximum wet bulb of 28° C (at
temperatures from 25° C to 35° C)
Trapezoidal, 25 g, velocity change is based on Product weight
5 Hz @ 0.0002 g2/Hz to 350 Hz @ 0.0002 g2/Hz
Input acceleration is 0.26 g RMS
10 minutes per axis for all 3 axes on all samples
Random control limit tolerance is ± 3 dB
International (CISPR 22) Radiated Limits for Radiating Class A & B Devices
Frequency range(MHz)/Class A and Class B(10 meters limits):
30MHz to 300 MHz / 40 dB ( V/m) and 30 dB ( V/m)
200MHz to 1000 MHz / 47 dB ( V/m) and 37 dB ( V/m)
HDD class
Class 1: Highest performance, reliability, and data integrity
Class 2: A second tier of performance, reliability, and data integrity
HDD I/O throughput degradation SPEC
Pass/Fail Criteria
No functional failure during test or post test diagnostics.
Requirement to pass test is based on IOMeter data throughput (in IO's per
second) expressed as a percent of Test HDD maximum theoretical baseline
performance
Class1: > 90% of baseline for 4K Random Writes and > 80% of baseline for 128K
Sequential Writes.
Class2: > 85% of baseline for 4K Random Writes and > 75% of baseline for 128K
Sequential Writes.
Mix: > 80% of baseline for 4K Random Writes and > 70% of baseline for 128K
Sequential Writes.
