The Iron Wolf ST6000VN001 is a 3. 5-inch hard disk with 6 terabytes (6, 000 GB) of storage space, designed by Seagate specifically for long-lasting continuous use in NAS servers or home server systems. The drive features a state -of-the- art SATA 6G interface , a 256 MB cache, and platters rotate at 5, 400 rpm . Due to the reduced speed, the HDD has a low power consumption of only 9 watts and can simultaneously transmit data with a sustained data throughput of brisk 210 MB / s. The Iron Wolf series NAS hard drives feature Seagate s Agile Array technology. This offers improved Hard 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). Optimized power profiles enable low power consumption for NAS applications with continuous operation.
