SEAGATE Surveillance Skyhawk 8Tb Hdd

Sustained data transfer rate OD (MiB/s max): 200 (210 MB/s max). Non-Operating temperature -40`b0 to 70`b0C (Ambient Temperature, see sections 2.6 and 2.11).

Key features

• Areal density, (Gb/in2, @ 0 skew mid-disk): 930
• ATA data-transfer modes supported
• Altitude, nonoperating: -304.8 m to 12,192 m (-1000 ft to 40,000+ ft)
• Operational Shock (max at 2 ms - typical): Read 70 Gs / Write 40 Gs
• Non-Operational Shock (max at 2 ms - typical): 300 Gs
• Drive acoustics, sound power (bels): Idle
• During periods of drive idle, some offline activity may occur according to the
• Smart specification, which may increase acoustic and power to operational levels.
• Maximum Rated Workload: Maximum rate of - Workloads exceeding the annualized rate may degrade the drive MTBF and impact
• product reliability.
• The Annualized Workload Rate is in units of TB per year or TB per 8760 power on
• hours. Workload Rate = TB transferred x (8760 / recorded power-on hours).
