  • 12TB capacity stores massive datasets in a single 3.5in drive
  • 7200 RPM spindle delivers fast sequential throughput for heavy workloads
  • 256MB cache with Advanced Write Caching and TurboBoost boosts burst performance and protects data during power loss
  • 24x7 rated reliability handles continuous operation in demanding environments
  • SATA interface ensures broad compatibility and easy integration

12 TB SATA drive for desktop storage

The Seagate ST12000NM0007 is a 3.5-inch internal hard drive that delivers 12 TB of capacity over a standard SATA interface. It spins at 7200 RPM and includes a 256 MB cache to support sustained read and write workloads. The drive is designed for continuous 24x7 operation in desktop and entry-level server environments.

Suits high-capacity archival and bulk-data workloads

This drive fits users who need a single large volume for media libraries, backups or surveillance footage and who can work within SATA throughput limits. It is not for systems that only accept 2.5-inch bays or that require the lower latency of solid-state storage. Builders without a free 3.5-inch mount and a SATA power and data connection should look elsewhere.

7200 RPM spindle speed defines sustained throughput

The 7200 RPM rotation rate sets the baseline sequential transfer rate that the SATA bus can deliver. If your workload demands higher random IOPS or lower access times than a mechanical drive provides, this specification indicates the drive will not meet that requirement.

Questions about this item

How much power does the 12TB 7200 RPM drive draw during continuous 24x7 operation?

The drive includes a customizable power option designed to reduce total cost of ownership during sustained 24x7 workloads, though the exact wattage figure is not supplied.

Which host interface and physical bay does this 3.5in SATA drive require?

It connects via a standard SATA data and power cable and fits any 3.5in internal drive bay with matching SATA ports on the motherboard or controller.

Will the 256MB cache and TurboBoost write caching work with an older SATA 3Gbps controller?

The drive is SATA compatible and its Advanced Write Caching with TurboBoost functions on any SATA link, but peak throughput will be limited by the older controller's 3Gbps ceiling.
