Capacity and interface

This Seagate BarraCuda 7200.12 drive provides 1TB of storage on a 3.5 inch form factor with a SATA 3.0Gb/s interface. It spins at 7200 RPM and includes 32MB of cache for desktop workloads.

Suitable uses and limits

The drive suits builders adding bulk storage to a desktop system that accepts a SATA 3.0Gb/s connection and a 26.10mm drive height. Buyers who need a drive without any bad sectors or who require a larger cache should look elsewhere.

Deciding specification

The SATA 3.0Gb/s interface is the single specification that determines whether this drive will connect to your motherboard or controller. Verify that your system supports this interface before purchase.

Soalan tentang produk ini

How long before the 7200 RPM spindle and 32MB cache hit their sustained throughput ceiling?

The 7200 RPM spindle and 32MB cache deliver consistent desktop performance; sustained throughput is limited by the SATA 3.0Gb/s interface and the drive's mechanical latency of 4.16ms.

What noise, heat or power profile should I expect when the 3.5" drive runs all day?

The 3.5" form factor at 7200 RPM produces typical desktop drive acoustics and heat; adequate case airflow keeps temperatures in normal operating range during continuous use.

Which existing SATA port and power connector must my system already have for this bare drive to work?

Your motherboard needs a free SATA 3.0Gb/s port and the power supply must provide a standard SATA power connector for the bare drive to operate.
