The Seagate ST8000AS0003 is an 8TB internal hard drive built for administrators and integrators who need dependable, energy-aware capacity in servers, JBOD arrays, and large desktop enclosures. It uses a 3.5 inch form factor and connects through a SATA 6Gb/s interface, making it a direct drop-in for any system that accepts standard SATA drives.

Designed for round-the-clock duty, the drive supports workloads up to 180TB per year and carries a mean time between failures of 800,000 hours. This level of durability allows it to sit comfortably in data center racks, surveillance back ends, or enterprise NAS appliances where continuous operation is the rule rather than the exception.

A 5400 RPM spindle works alongside a 256MB cache to deliver reliable sequential throughput while generating less heat and vibration than faster-spinning alternatives. When paired with Seagate PowerChoice, the drive can transition into lower-power states during idle periods, trimming energy costs and easing thermal load in densely populated enclosures.

Typical use cases include cold or warm archive tiers, backup repositories, and compliance storage where data is written once and accessed occasionally. Home lab builders and small businesses can also deploy the drive in RAID arrays to consolidate large media libraries or long-term project files without the power draw of higher-speed disks.

Compatibility is straightforward: any chassis that accepts a 3.5 inch by 1.0 inch SATA drive can house the ST8000AS0003. Standard SATA power and data connectors mean there is no need for proprietary cables or adapters, keeping installation simple and maintenance predictable.

Highlights:
  • 8TB capacity in a 3.5 inch form factor
  • SATA 6Gb/s interface with 256MB cache for steady data flow
  • 5400 RPM spindle helps reduce heat, noise, and vibration
  • Workload rating of 180TB per year for 24/7 operation
  • Mean time between failures of 800,000 hours supports long service life
  • PowerChoice technology lowers energy use during idle periods
  • Fits any bay that accepts a 3.5 inch SATA drive
