Seagate BarraCuda 320GB 3.5" SATA Drive

This 3.5-inch internal hard drive provides 320GB of storage on a SATA 6.0Gb/s interface. It spins at 7200 RPM with a 16MB cache and is supplied as a bare drive. The BarraCuda series is built for desktop and server workloads.

Suited for capacity expansion in desktops

This drive fits systems that need a 3.5-inch SATA mechanical disk for bulk storage or boot duties. It is not for builds that require solid-state speed, larger capacities, or a 2.5-inch form factor.

7200 RPM spindle speed

The 7200 RPM rotation rate sets the baseline throughput and access latency for this model. Buyers should confirm that this speed matches the performance target of their workload before purchasing.

商品問答

Does the 3.5" form factor fit a standard desktop drive bay?

Yes, the 3.5 inch form factor matches standard desktop drive bays and uses the common SATA data and power connectors.

What is the correct way to connect the SATA 6.0Gb/s interface, and what step is often missed?

Attach both the SATA data cable to the motherboard port and the SATA power cable from the power supply; the step often missed is connecting the power cable.

How often will the 16MB cache or mechanical parts need replacement under the 0.34% predicted failure rate?

The 0.34% predicted failure rate indicates high reliability; mechanical drives have no user-serviceable cache or parts, so replacement is only needed if the drive itself fails.
