Description

The Seagate® Exos™ 7E8 enterprise hard drive confidently stores up to 8 TB of data without sacrificing performance. The secure, highcapacity, high-performance drives are optimised for demanding enterprise bulk data applications.

Enterprise Drive for Bulk Data Applications
Exos 7E8 hard drives support up to 8 TB per drive, offering bulk data storage for data centre infrastructures requiring a highly reliable enterprise hard drive. Exos 7E8 provides cost effective, reliable access to unstructured data. Built on field-proven 9thgeneration conventional magnetic recording (CMR) technology, the Exos 7E8 drive helps to catalyse the datasphere, enabling data centre architects and IT professionals to deliver trusted performance, rock-solid reliability, ironclad security and low TCO for demanding 24×7 operations.

Robust Bulk Data Storage for a 24×7 World
Exos 7E8 drives are backed by a 2 million hour MTBF rating and support workloads of 550 TB per year — 10× that of desktop hard drives. With state-of-the-art cache, on-thefly error correction algorithms and rotational vibration design, the Exos 7E8 helps ensure consistent performance in replicated and RAID multi-drive systems.

High Performance for Mainstream Data Centre Applications
Meet your storage workload requirements in the most efficient and cost-effective data centre footprint on the market today. The Exos 7E8 delivers easy integration into bulk storage systems with 12 Gb/s SAS and SATA 6 Gb/s interface options. With userdefinable innovative technology advancements like PowerChoice™ and Seagate RAID Rebuild®, you can tailor your nearline storage requirements for even greater improvements in lowering your TCO.

Enhanced Enterprise Reliability, Data Protection and Security
Advanced security features help protect data where it lives — on the drive. Exos 7E8 prevents unauthorised drive access and safeguards stored data with security features that include Secure Downloads & Diagnostics, TCG-compliant Self-Encrypting Drive and government-grade FIPS/Common Criteria tamper-resistant hard drive. Seagate Secure™ drives simplify drive repurposing and disposal, help protect data-at-rest and comply with corporate and federal data security mandates.
