Seagate Exos 7E8 8TB 3.5´´ HDD

The Seagate® Exos® 7E8 enterprise hard drive confidently stores up to 8 TB of data without sacrificing performance. The secure, high-capacity, 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 centreinfrastructures requiring a highly reliable enterprise hard drive. Exos 7E8 provides costeffective, reliable access to unstructured data. Built on field-proven 10th-generation 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 TBper year — 10× that of desktop hard drives. With state-of-the-art cache, on-the-fly errorcorrection 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 user-definable innovative technology advancements like PowerChoice™ and Seagate RAID Rebuild ®, you can tailor your nearlinestorage requirements for even greater improvements in lowering your TCO.

Enhanced 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. 2 Seagate Secure™ drives simplify drive repurposing and disposal, help protect data-at-rest, and comply with corporate and federal data security mandates.
