Capacity and interface

The Seagate BarraCuda ST31000524AS is a 1 TB 3.5 inch desktop hard drive that spins at 7200 RPM with a 32 MB cache. It connects through a SATA 6.0 Gb/s interface and is sold as a bare drive in new condition. The series targets general desktop storage and server workloads that benefit from high sequential throughput.

Build integration

The drive fits any standard 3.5 inch bay and requires a SATA data cable plus a SATA power connector from the power supply. Native Command Queuing support helps the controller optimise request order, reducing latency during mixed workloads. The 6.0 Gb/s link provides twice the bus bandwidth of the previous 3.0 Gb/s revision, freeing headroom for sustained transfers.

Accessories and software

No cables, brackets or software utilities are included with the bare drive package. The unit has been erased to DoD 5220.22 M compliance and tested functional, though up to 25 bad sectors may be present and cosmetic markings can vary. Manufacturer warranty has ended; the seller provides a one year coverage instead.

Questions about this item

How many bad sectors might appear before the drive reaches its usable limit?

The supplier notes that up to 25 bad sectors may be present on a tested unit.

What is the predicted annual failure rate when the drive runs continuously?

The manufacturer highlights a predicted failure rate of .34% for the Barracuda 7200.12 series.

Which SATA revision must the host controller support for full 6.0Gb/s throughput?

The drive uses SATA Revision 3.0, so the controller must support that revision for maximum bus bandwidth.
