Seagate ST8000NM0055 8TB 3.5" 7200RPM Enterprise SATA/SAS Internal Hard Drive

Enterprise-class 8TB, 3.5-inch nearline drive using Seagate’s 6-disk architecture to deliver 33% more capacity in the same drive slot. Built for heavy, always-on environments, it combines performance, reliability and data integrity for large-scale storage deployments. Performance features: Advanced Write Caching with enhanced algorithms provides industry-leading nearline workload efficiency—delivering a 100% improvement in random write performance versus the previous-generation drive. The drive uses ninth-generation conventional perpendicular recording (CMR) for dependable access to unstructured bulk data. Interfaces and integration: Supports 12Gb/s SAS and SATA 6Gb/s interfaces in industry-standard advanced formats for straightforward integration into replicated and RAID multi-drive servers and storage systems. Data protection and reliability: Modern cache management, on-the-fly error-correction algorithms, super parity and end-to-end SAS-based data integrity mechanisms ensure accurate storage. Industry-leading rotational vibration tolerance helps maintain consistent performance in dense multi-drive enclosures. Durability and environmental features: Engineered for 24/7 workloads of 550TB/yr — 10× that of desktop drives — and designed with dual processors, ramp load technology, a top-cover-attached motor and a humidity sensor to optimize operation across chassis designs. Security and tools: Seagate Secure™ Self-Encrypting Drive with Instant Secure Erase provides secure data-at-rest protection and cost-effective drive retirement. Includes Seagate SeaTools™ diagnostic software for drive self-tests to reduce downtime and maximize TCO. Typical use cases: Hyperscale and cloud data centers with replicated storage, massive scale-out and big-data analytics clusters, high-density RAID arrays, mainstream enterprise external storage arrays (SAN, NAS, DAS), distributed file systems (including Hadoop and Ceph), enterprise backup/restore (D2D, virtual tape) and centralized surveillance.
