300 GB 7200 RPM desktop drive

This 3.5 inch Seagate BarraCuda 7200.8 model ST3300831AS provides 300 GB of storage on a SATA 1.5Gb/s interface. It spins at 7200 RPM with an 8 MB cache and 4.16 ms average latency. The bare drive includes NCQ support, a SoftSonic motor and Enhanced G-Force Protection. Condition is new.

Suits older SATA desktops not faster interfaces

This drive fits systems built for SATA 1.5Gb/s where a 300 GB 7200 RPM mechanical disk matches the original specification. Builders who need higher throughput or larger volumes should look at newer interfaces. The bare drive packaging means no cables or brackets are included.

SATA 1.5Gb/s interface decides compatibility

The single specification that determines fit is the SATA 1.5Gb/s interface; the host must provide this exact connection. Capacity of 300 GB and 7200 RPM speed follow from the drive design but the interface is the deciding factor.

商品問答

What size drive bay does the 3.5" BarraCuda 7200.8 need?

The ST3300831AS fits a standard 3.5-inch internal bay and uses the regular SATA data and power connectors found on desktop motherboards and power supplies.

Which jumper or BIOS step is often missed when installing this SATA 1.5Gb/s drive?

No jumper is required for SATA operation; the common mistake is leaving the SATA controller disabled in BIOS so the 300GB drive does not appear at boot.

When should the 8MB cache drive be replaced under normal desktop use?

Plan replacement if SMART attributes show reallocated sectors, seek errors climb, or the SoftSonic motor develops unusual noise after several years of 7200 RPM operation.
