320 GB desktop SATA hard drive

This 3.5 inch internal drive provides 320 GB of storage on a SATA 3 Gb/s interface. It spins at 7200 RPM and includes a 16 MB buffer for everyday desktop workloads. The unit is supplied new and weighs 2.0 pound.

Suits basic storage upgrades.

This drive fits older desktops or secondary storage roles where a modest 320 GB capacity is sufficient. Builders who need more space for modern games, media libraries or backups should look at larger drives. The 3 Gb/s SATA link also limits throughput compared with 6 Gb/s models.

The 320 GB capacity decides fit

At 320 GB this drive only matches lightweight storage requirements such as an operating system drive or a small file archive. If the project demands several hundred gigabytes or terabytes of space this capacity will fall short. Choose a larger model when the storage budget exceeds this figure.
