40 GB 7200 RPM SATA drive

The Seagate Barracuda 7200.7 ST340014AS is a 3.5 inch internal hard drive with a 40 GB capacity and a 7200 RPM spindle speed. It connects via a SATA 1.5 Gbps interface and includes a 2 MB cache buffer. This new drive suits legacy desktop builds or replacement scenarios where a small SATA drive is required.

SATA 1.5 Gbps interface limit

The SATA 1.5 Gbps interface caps the maximum theoretical transfer rate at 1.5 Gbps, which is well below the throughput of later SATA revisions. The 7200 RPM rotational speed and 2 MB buffer help sustain performance within that ceiling, but the interface itself remains the bottleneck for sequential and random access alike.

40 GB capacity and headroom

With 40 GB of storage, the drive accommodates a lightweight operating system, essential applications and a modest collection of documents. It runs out quickly when storing media libraries, modern games or large project files, making it unsuitable for users who need more space for current workloads.

Questions about this item

Should I choose the 40 GB version or look for a larger capacity?

This model is the 40 GB capacity; the listed part number ST340014AS refers specifically to that size.

What does the 7200 RPM spindle speed mean for daily use?

The 7200 RPM rotation gives faster data access than slower desktop drives, improving boot and application load times.

How does the SATA 1.5 Gbps interface affect real-world throughput?

The SATA 1.5 Gbps link caps the maximum transfer rate at that bus speed, so sustained reads and writes cannot exceed the interface limit.
