Seagate ST8000NM0055 8TB 7200RPM Enterprise HDD

The Seagate ST8000NM0055 is an enterprise-grade 3.5-inch hard drive offering 8TB of storage capacity at 7200 RPM. Designed for bulk-data applications in data centers and hyperscale environments, it uses Conventional Magnetic Recording (CMR) technology, which provides predictable and consistent write performance — an important distinction from SMR drives that can experience write slowdowns during sustained operations. The 256MB cache buffer helps smooth out data transfers, and the SATA 6Gb/s interface ensures broad compatibility with standard server and NAS hardware.

Built for around-the-clock operation, the drive carries a 550TB/year workload rating, placing it firmly in the enterprise tier for sustained read and write duties. Rotational vibration tolerance is built in, which is essential for maintaining performance and reliability when the drive is mounted in dense, multi-drive enclosures where vibration from neighboring drives is unavoidable. Seagate also includes Secure Self-Encrypting Drive (SED) technology, enabling hardware-level encryption without the performance overhead of software-based solutions. Advanced write caching further optimizes throughput for sequential workloads common in archival, surveillance, and large-scale data storage scenarios.
