The IronWolf ST4000VN008 is a 3.5-inch 4 terabyte (4,000GB) hard drive designed by Seagate for long-lasting, long-lasting use in NAS servers or home server systems.The drive has a state-of-the-art SATA 6G interface, a 64MB cache, and the platters rotate at 5,900rpm. Due to the reduced speed, the HDD has a low power consumption of only 4.8 watts and can simultaneously transmit data with a sustained data throughput of brisk 180MB/s.The IronWolf series NAS hard drives feature Seagate\'s AgileArray technology. This provides improved disk balance, RAID optimization and reduced power consumption. Advanced troubleshooting ensures that your hard drive meets NAS system requirements for better data integrity.Reducing the vibration effects typically associated with multi-disk solutions improves reliability. This is made possible by integrated sensors for measuring rotational vibrations (RV). Optimised power profiles enable low power consumption for NAS applications with continuous operation.Technical details:- Dimensions: 101.6 x 26.1 x 147mm (W x H x D)- Format: 3.5 inches- Weight: about 610g- Capacity: 4TB- Speed: 5,900rpm- Cache: 64MB- Maximum sustained data transfer rate: 180MB/s- Connection: SATA 6G- Power consumption (idle / operation): 3.95 / 4.8W- Starting current : max. 2.0A- Shock resistance (during operation): 70 G for 2ms- Operating temperature: 0-60C- Life expectancy: 1 million h (MTBF)- Recovery: 3 Years Data Recovery - Manufacturer\'s warranty: 3 years
