Seagate

Seagate ST8000NM0055 8TB SATA 6Gbps 3.5in Enterprise Hard Drive

SKU CH-QTCC-H1B3W

An 8 TB 3.5-inch enterprise hard drive with SATA 6 Gbps interface, 33 % more capacity per slot and 100 % faster random writes than the previous generation

  • 8TB capacity fits bulk-data workloads in a single 3.5in slot
  • 33% more storage from six-disk design without extra space
  • 100% random-write performance gain over previous generation
  • 550TB per year workload rating for 24×7 operation
  • SATA 6Gbps and SAS 12Gbps interfaces for RAID integration

Capacity and Interface

The Seagate ST8000NM0055 is an 8TB 3.5-inch enterprise hard drive built for bulk-data workloads. It uses a SATA 6Gbps interface and six-disk helium technology to deliver 33 percent more capacity in the same slot.

Workload Suitability

This drive suits operators running 24/7 nearline storage servers that demand 550TB per year endurance and high rotational-vibration tolerance. It is not for desktop users who need only occasional access or who require the lower power draw and acoustics of consumer drives.

Deciding Specification

The 550TB per year workload rating is the single figure that determines fit; systems expecting lighter or heavier annual write volumes should evaluate a different drive class.

Highlights

  • 8TB capacity fits bulk-data workloads in a single 3.5in slot

  • 100% random-write performance gain over previous generation
  • 550TB per year workload rating for 24×7 operation
  • SATA 6Gbps and SAS 12Gbps interfaces for RAID integration

Questions about this item

Will the ramp-load mechanism and top-cover-attached motor need replacement during the 550 TB yearly workload?

The ramp-load technology and top-cover-attached motor are built for continuous 24x7 operation at the 550 TB per year rating, so no scheduled replacement is required within that workload.

What workload limit appears first when the drive runs at the full 550 TB per year rating?

The 550 TB per year workload rating is the primary limit; sustained writes at that level will reach the rated endurance before any other specified threshold.

How much heat and power should I expect when the drive operates 24 hours a day in a multi-drive chassis?

Engineered for 24x7 workloads with industry-leading rotational vibration tolerance, the drive maintains consistent performance in dense systems without exceeding enterprise thermal or power envelopes.
