Desktop storage for everyday computing
This Seagate BarraCuda 7200.10 drive provides 320GB of internal storage for desktop PCs. The 3.5 inch form factor fits standard drive bays and the SATA 3.0Gb/s interface connects directly to compatible motherboards. It suits users adding a secondary drive for documents, media or backup tasks. Builders needing higher capacities or faster interfaces should consider other options.
Thermals noise and power in normal use
The drive spins at 7200 RPM with an average latency of 4.16ms and is described by the manufacturer as whisper-quiet during operation. Perpendicular recording technology helps maintain reliability while the 8MB cache buffers routine read and write requests. No specific power-draw figures are supplied so thermal output under sustained load cannot be quantified.
Included accessories and software impact
The product is supplied as a bare drive without cables, mounting screws or installation software. Enhanced G-Force Protection guards against handling shocks before the drive is mounted. Clean Sweep calibration and Directed Offline scan diagnostics run in the background to maintain data integrity. RoHS compliance confirms restricted substances are limited in the manufacturing process.

Fragen zu diesem Artikel
How do I install this 3.5" SATA drive and what step is often missed?
Mount the drive in a 3.5" bay, connect the SATA data cable to a 3.0Gb/s port and attach a SATA power connector; the step often missed is ensuring the motherboard SATA controller is set to AHCI mode in BIOS for full 78 MB/s sustained transfer performance.
What maintenance or replacement will this ST3320820AS need over time?
As a mechanical 7200 RPM drive with perpendicular recording, it requires no scheduled maintenance; plan replacement when SMART attributes report reallocated sectors or when the 4.16ms average latency rises noticeably during sustained workloads.
What limit appears first during sustained use of this 320GB BarraCuda?
The 78 MB/s maximum sustained data transfer rate of the SATA 3.0Gb/s interface becomes the bottleneck before the 8MB cache or 7200 RPM spindle can saturate the bus during large sequential reads or writes.
