Capacity and interface

This is a new 80 GB 3.5-inch internal hard drive with a SATA 3.0 Gb/s interface. It suits desktop builds that need a small amount of storage for an operating system or legacy applications. The bare-drive packaging means no cables or brackets are included.

Sustained throughput and latency

The drive spins at 7200 RPM with a 2 MB cache and delivers a maximum sustained data transfer rate of 78 MB/s. Average latency is 4.16 ms. Perpendicular recording technology supports capacity and reliability during continuous operation.

Compatibility checks

Verify that your motherboard or controller provides a free SATA 3.0 Gb/s port and that the power supply has an available SATA power connector. Ensure the chassis has a 3.5-inch drive bay with mounting points for a bare drive.

Questions about this item

How much power and heat does the 7200 RPM BarraCuda 7200.10 generate during all-day operation?

The drive uses perpendicular recording technology and Enhanced G-Force Protection for reliable operation, with whisper-quiet acoustics and a 4.16 ms average latency at 7200 RPM.

What cables or host interface must I already have to install this ST380215AS?

It requires a SATA 3.0 Gb/s data cable and a standard SATA power connector from the system power supply.

Will this 80 GB SATA 3.0 Gb/s drive work alongside an older IDE hard drive in the same PC?

Yes, it connects via SATA 3.0 Gb/s while an IDE drive uses a separate PATA interface, so both can coexist on a motherboard that provides both connectors.
