About Seagate Exos 7E10 4TB

The Seagate Exos 7E10 4TB (ST4000NM001B / ST4000NM025B) is an enterprise-grade hard drive built for high-density data centers and mission-critical applications. Unlike consumer drives, the Exos series is engineered for extreme reliability and performance in high-vibration, multi-drive environments.Enterprise-Level PerformanceThe drive operates at a robust 7,200 RPM spindle speed and utilizes the 12Gb/s SAS (Serial Attached SCSI) interface. This combination allows for a maximum sustained data transfer rate of up to 250 MB/s. With a large 256MB cache and advanced write caching (using internal NOR flash), the Exos 7E10 excels in handling the random I/O workloads common in server environments and RAID arrays.Built for 24/7 ReliabilityDesigned for continuous operation, the Exos 7E10 features a workload rating of 550TB per year—roughly 10 times that of a standard desktop drive. It boasts a 2 million-hour Mean Time Between Failures (MTBF) and a low annualized failure rate (AFR) of 0.44%.FeatureSpecificationInterfaceSAS 12Gb/s (Dual Port)Capacity4TBSpindle Speed7,200 RPMMax Transfer Rate250 MB/sWorkload Rate550TB / yearWarranty5-Year LimitedKey TechnologiesRotational Vibration (RV) Sensors: Maintains performance in dense, multi-drive enclosures by compensating for external vibrations.PowerChoice™ & PowerBalance™: Allows IT managers to customize power consumption for better energy efficiency and lower Total Cost of Ownership (TCO).Seagate Secure™: Provides options for self-encrypting drive (SED) models to protect data-at-rest and simplify drive decommissioning.This drive is ideal for hyperscale applications, cloud data centers, and massive scale-out RAID storage.
