BarraCuda LP 1.5TB Desktop Drive

The Seagate BarraCuda LP ST31500541AS is a 3.5 inch internal hard drive with 1.5TB capacity. It runs at 5900 RPM with 32MB cache and connects through a SATA 3.0Gb/s interface. The drive is supplied as a bare unit in new condition.

Suits bulk storage and quiet builds

This drive suits desktop PCs that need large, low-cost capacity for archives, media libraries or backup volumes. Its 5900 RPM spindle and 25dB idle acoustics keep noise and heat low. It is not for systems that need higher spindle speeds for active workloads, nor for devices that only accept 2.5 inch drives.

5900 RPM spindle speed

The 5900 RPM rotation rate determines the drive's sustained transfer performance and acoustic profile. Buyers who need faster sequential throughput should consider drives with higher RPM ratings.

Questions about this item

Will the 1.5TB SATA 3.0Gb/s drive work in a system that only has SATA 1.5Gb/s ports?

Yes, the SATA 3.0Gb/s interface is backward compatible with SATA 1.5Gb/s controllers, so the drive will operate at the slower 1.5Gb/s speed.

How can I confirm the 5900 RPM drive is healthy after installation?

Run the manufacturer's SeaTools diagnostic or check SMART attributes for reallocated sectors; the drive was tested DoD 5220.22 M compliant and may have up to 25 bad sectors.

Does the bare drive include a SATA data cable, power adapter or mounting screws?

No, the bare drive packaging supplies only the 3.5" hard drive itself; cables, adapters and screws must be purchased separately.
