Hard Drives in Extreme Settings
Entertainment, navigation and productivity/control data live side by side in emerging applications that are exposed to extreme conditions but expected to be accessible on demand. Automotive, marine and aircraft systems increasingly carry audio and video content; military systems and ruggedized computers deliver (literally) mission-critical information; and all require the hard drive’s capacity and value, even in hostile, extreme environments.
The second generation of 2.5-inch EE25 Series™ drives from Seagate® is designed for the temperature, vibration, humidity and other environmental requirements of these applications.
- Operating temperature specifications of –30°C to 85°C make the EE25 Series drive resistant to environmental conditions that would cause lesser drives to fail.
- Operating altitude as high as 16,400 feet (5000 meters) and as low as –1000 feet (–305 meters)below sea level.
- Delivers reliability in environments with operating vibration up to 2.2 Gs
- RunOn™ technology reliably delivers multimedia content under high-vibration, highhumidity, extreme-temperature conditions.
Markets and Applications
- Automotive, military, aerospace, marine, industrial and commercial applications requiring storage solutions capable of operating in extreme environments.
- Embedded fanless computing systems (EE25 Series drives do not need add-on heaters or cooling devices.)
Partnership—Seagate Design Service Centers assist OEMs with integrating the drive into hardened computing and entertainment systems designed for use in extreme environments.
Reliable Performance in Extreme Environments
The second-generation Seagate EE25 Series drive provides affordable, rugged digital storage with high reliability, in capacities up to 80 GB, with full operating capability from –30°C to +85°C and 2-G vibration robustness from 5 to 500 Hz, at altitudes from –1000 to 16,400 feet (–305 to 5000 meters). The EE25.2 Series drive, available in native PATA and SATA configurations, helps avoid the high costs of solid-state storage. The world of rugged storage is expanding quickly; take advantage of the growth with this extreme-environment hard drive.
