1TB SATA 3.0Gb/s Desktop Drive

The Seagate BarraCuda 7200.11 ST31000340AS is a 1TB 3.5-inch internal hard drive for desktop computers. It spins at 7200 RPM with a 32MB cache and connects through a SATA 3.0Gb/s interface. The drive uses second-generation perpendicular recording technology and supports Native Command Queuing.

Suits Capacity-Focused Desktop Builds

This drive suits users adding bulk storage to a desktop that accepts a 3.5-inch SATA drive. It is not for systems limited to 2.5-inch bays or laptops. Buyers needing an out-of-the-box formatted volume should look elsewhere, as the drive ships unformatted and unpartitioned. It also does not suit anyone requiring a pristine cosmetic appearance, since labels may show markings or colour variation.

25-Bad-Sector Allowance Is The Deciding Factor

The supplier notes that units may contain up to 25 bad sectors and are sold as tested working used drives despite the new condition flag. This tolerance is the single specification that determines whether the drive matches your reliability requirements. If your workload cannot accept any defective sectors, choose a different drive.

Perguntas sobre este artigo

What size drive bay and interface does the 3.5" ST31000340AS need to mount and connect?

The drive fits a standard 3.5" bay and connects via a SATA 3.0Gb/s data cable plus a SATA power connector from the PSU.

How is the BarraCuda 7200.11 installed, and what step is often missed?

Secure the drive with four 6-32 screws, attach both SATA data and power cables, then initialise and format the 1TB volume in Disk Management before use.

When will the ST31000340AS need maintenance or replacement?

Replace the drive if SMART reallocated sectors approach the 25-sector threshold or if seek errors appear, as the 7200 RPM mechanism ages.
