Enterprise bulk-data capacity

The Seagate ST8000NM0055 is an 8TB 3.5-inch enterprise hard drive built for bulk-data applications. It uses 7200 RPM spindle speed and a 256MB cache on a SATA 6.0Gb/s interface. The six-disk design delivers 33% more storage in the same slot. It is suited for storage arrays, backup targets and archival workloads that prioritise capacity over latency.

Compatibility checks

Verify that your system has a free 3.5-inch drive bay and a SATA data and power connection. The drive measures 147.00mm long, 101.85mm wide and 26.10mm high, so confirm clearance in compact chassis. Ensure your host controller supports SATA/600 for full throughput. This is a bare OEM drive without cables or mounting hardware.

Thermals and power

Enterprise drives run continuously, so provide adequate airflow across the 3.5-inch form factor. The 7200 RPM spindle and six platters generate more heat than lower-speed models. PowerChoice technology helps manage draw during idle periods. Self-encrypting drive hardware and Instant Secure Erase add security without a measurable performance penalty. Expect typical enterprise acoustic levels under sustained loads.

商品問答

What comes in the box and what cables or brackets must be bought separately?

The drive ships as a bare 3.5-inch unit without SATA data or power cables, mounting screws or a tray; those items must be sourced separately.

Which version or capacity of the Enterprise Capacity 3.5 series should I choose?

This model is the 8TB variant with 7200 RPM, 256MB cache and SATA 6.0Gb/s; other capacities in the same series differ in storage size but share the same interface and form factor.

What does the 7200 RPM spindle speed mean for real-world throughput in a desktop or server?

The 7200 RPM rotation yields an average latency of 4.16ms and supports sustained transfers up to the SATA 6.0Gb/s link limit, making it suited for bulk-data workloads in enterprise storage arrays.
