Capacity and Interface

This Seagate BarraCuda 7200.11 desktop internal hard drive provides 750GB of storage on a SATA 3.0Gb/s interface. The 3.5 inch form factor fits standard drive bays and the bare drive packaging is intended for system integrators. It spins at 7200 RPM with a 32MB cache to handle everyday workloads.

Server Focus

The manufacturer highlights suitability for server deployments where sustained throughput matters. Buyers who need a faster interface than SATA 3.0Gb/s or a larger capacity than 750GB should consider other options. Those requiring a 2.5 inch form factor for compact chassis will also need a different drive.

Deciding Specification

The SATA 3.0Gb/s interface speed is the single specification that determines compatibility with your host controller. Verify that your motherboard or backplane supports this revision before purchase. The 4.16ms average latency and 7200 RPM spindle speed are fixed characteristics of this model.
