BarraCuda 7200.9 300GB Desktop Drive

The Seagate BarraCuda 7200.9 ST3300822AS is a 300GB 3.5-inch internal hard drive built for desktop computers. It spins at 7200 RPM with an 8MB cache and connects through a SATA 3.0Gb/s interface. The bare-drive unit includes NCQ support and a 3-D Defense System for mechanical protection. It suits users adding affordable bulk storage to an older SATA platform.

Ideal for Legacy SATA Upgrades

This drive fits systems that still rely on the SATA 3.0Gb/s bus and need a straightforward capacity increase. It works well for secondary storage, backups or a boot volume where solid-state speed is not required. Builders working with newer 6Gb/s controllers or compact 2.5-inch bays should look elsewhere, as the 3.5-inch form factor and 3Gb/s link limit throughput and physical compatibility.

300GB Capacity with 7200 RPM Headroom

The 300GB platter space handles operating systems, applications and media libraries for everyday desktop workloads. Average seek time of 8ms and latency of 4.16ms keep file access responsive for general use. Heavy multitasking, large video projects or modern gaming libraries will exhaust the available space and cache headroom quickly, so plan for additional drives if those demands apply.

Questions about this item

What SATA port and power cable do I need for the ST3300822AS?

The drive connects to a SATA 3.0Gb/s data port and requires a standard SATA power connector from your power supply.

Will the 8ms seek time and SATA 3.0Gb/s link feel slow next to a modern SSD?

Yes, the 7200 RPM platter and 8ms average seek are much slower than solid-state storage for boot and application loading.

How can I verify the 300GB capacity and 7200 RPM speed after installation?

Check the drive properties in your OS or BIOS; they should report 300GB and 7200 RPM for the ST3300822AS.
