Seagate BarraCuda 7200.12 160GB Desktop Drive

The Seagate BarraCuda 7200.12 ST3160318AS is a 160GB 3.5-inch internal hard drive built for desktop computers. It operates at 7200 RPM with an 8MB cache and connects through a SATA 3.0Gb/s interface. This bare drive suits users replacing a failed drive or adding modest storage to an older system.

SATA 3.0Gb/s Interface Throughput Limit

The SATA 3.0Gb/s interface caps the maximum theoretical transfer rate at 300 MB/s. Real-world sustained speeds will be lower due to the mechanical nature of the drive and protocol overhead. Builders needing the higher bandwidth of SATA 6.0Gb/s should verify their motherboard supports the faster standard before relying on this drive for throughput-sensitive tasks.

160GB Capacity Determines Fit

With 160GB of formatted space, this drive accommodates a lightweight operating system, essential applications and a small collection of documents. It will not hold modern game libraries, large media collections or extensive virtual machines. Buyers who need more storage must select a higher-capacity model.

商品問答

How do I know if the 160 GB capacity is right for my build?

The 160 GB capacity suits a boot drive for a lightweight operating system or as a secondary store for documents and older applications.

What does the 7200 RPM speed actually deliver in daily use?

The 7200 RPM spindle and 4.16 ms average latency give snappy file access and quicker program launches compared with slower desktop drives.

Will the SATA 3.0 Gb/s interface limit performance on a modern motherboard?

The SATA 3.0 Gb/s link caps the maximum transfer rate at 300 MB/s, so the drive cannot saturate a 6 Gb/s port but will still operate normally.
