Drive specifications
for rated MTBF device operating condition requirements.
Temperature gradient (°C per hour max)
20°C (operating)
20°C (nonoperating)
Relative humidity
5% to 95% (operating)
5% to 95% (nonoperating)
Relative humidity gradient
20% per hour max
Altitude, operating
–304.8 m to 3,048 m
(–1000 ft to 10,000+ ft)
Altitude, nonoperating (below mean sea level, max) –304.8 m to 12,192 m
(–1000 ft to 40,000+ ft)
Operational Shock (2 ms)
50 Gs typical
Non-Operational Shock (2 ms)
200 Gs
Linear Random Operating Vibration
5–500 Hz: 0.70 Grms
Random Rotary Operating Vibration
20–1500Hz: 12.5 rads/s²
Linear Random Non-Operating Vibration
2–500 Hz: 2.27 Grms
Drive acoustics, sound power (bels)
Idle
2.8 (typical)
3.0 (max)
During periods of drive idle, some offline activity may occur according to the
SMART specification, which may increase acoustic and power to operational levels
.
Performance seek
3.2 (typical)
3.4 (max)
Nonrecoverable read errors
1 sector per 10
15
bits read
Annualized Failure Rate (AFR)
0.35% based on 8760 POH
Maximum Rated Workload
Maximum rate of <550TB/year
Workloads exceeding the annualized rate may degrade the drive MTBF and impact prod-
uct reliability. The Annualized Workload Rate is in units of TB per year, or TB per 8760
power on hours. Workload Rate = TB transferred * (8760 / recorded power on hours).
