1 TB SATA desktop drive
The Seagate BarraCuda LP ST31000520AS is a 3.5 inch internal hard drive with 1 TB capacity, 5900 RPM spindle speed and 32 MB cache. It connects over a SATA 3.0 Gb/s interface and is supplied as a bare drive. The low-power design targets desktop systems that prioritise reduced energy draw over peak throughput.
Low power and cooler running
The drive consumes up to 50 percent less power than standard desktop models, which lowers heat output and can reduce component stress over time. Average latency is 5.1 ms at the rated spindle speed. The unit has been erased to DoD 5220.22 M compliance and tested functional; up to 25 bad sectors may be present.
Upgrade from smaller or hotter drives
This drive replaces lower-capacity desktop disks or higher-power units where a cooler, quieter 1 TB volume is preferred. The jump is worthwhile when the system can accept a SATA 3.0 Gb/s device and does not require the faster access times of solid-state storage. It is not suited for workloads demanding sustained high transfer rates or enterprise-grade reliability.

Questions about this item
How do I install the ST31000520AS 3.5" SATA drive and what step is often missed?
Mount the 3.5" drive in a bay, attach a SATA data cable to the motherboard and a SATA power connector from the PSU, then initialise and format the 1TB volume in Disk Management — the step often missed is creating the partition and file system after the drive appears in BIOS.
What maintenance or replacement will this 5900 RPM drive need later?
As a mechanical drive, the ST31000520AS may develop bad sectors over time; the supplier notes up to 25 bad sectors can be present on used units, so monitor SMART health and replace the drive if reallocated sector counts rise.
What limit appears first under sustained use on this 32MB cache SATA 3.0Gb/s drive?
The 5900 RPM spindle speed and 5.1ms average latency set the sustained throughput ceiling, so long sequential workloads will hit the mechanical transfer limit before the SATA 3.0Gb/s interface saturates.
