BarraCuda 7200.11 1TB desktop drive
The Seagate BarraCuda 7200.11 ST31000333AS is a 1TB 3.5-inch internal hard drive built for desktop computers. It spins at 7200 RPM with a 32MB cache and connects through a SATA 3.0Gb/s interface. The drive arrives as a bare unit without cables or mounting hardware.
SATA 3.0Gb/s integration and build space
Installation requires a standard 3.5-inch drive bay and a SATA data cable plus power connector from the power supply. The SATA 3.0Gb/s link works with any motherboard or controller that supports the interface. Using this mechanical drive for bulk storage leaves faster solid-state slots free for the operating system and applications.
Suited for high-capacity secondary storage
This drive suits builders who need a terabyte of affordable space for media libraries, backups or archival files. It is not for systems that require the low latency and high throughput of solid-state storage. Buyers who want faster boot and load times should look at solid-state alternatives. Those needing more than 1TB on a single drive will need a higher-capacity model.

Questions about this item
What sustained throughput can I expect from the SATA 3.0Gb/s interface on this ST31000333AS?
The SATA 3.0Gb/s link caps theoretical throughput at 3.0 Gb/s, so real-world sustained transfers will sit below that ceiling.
How much heat and noise does the 7200 RPM mechanism produce during all-day operation?
A 7200 RPM 3.5" drive generates noticeable warmth and audible seek noise under continuous load; ensure your case has adequate airflow.
Which power and data cables must I already have to install this bare 3.5" SATA drive?
You need a standard SATA data cable and a SATA power connector from your PSU; no adapter is required for the 3.5" form factor.
