ST3400832AS Seagate Barracuda 0.4TB SATA 8 MB 3.5" Consumer HDD

Enterprise 3.5in SATA Internal HDD featuring CMR reliability with the ST3400832AS

The ST3400832AS is a 3.5in internal SATA hard drive designed for predictable, low-latency rotational storage in server and workstation platforms where a dedicated OS/application volume or local scratch space is required. In mixed CPU environments and legacy enterprise boards, the SATA interface integrates cleanly with standard host controllers and backplanes, keeping PCIe lanes available for NICs, HBAs, or accelerators rather than consuming them with add-in storage.

Architecturally, ST3400832AS uses CMR recording to preserve consistent write behavior under sustained workloads, supporting dependable queue management through NCQ and operational visibility via S.M.A.R.T. monitoring. The 7200RPM class profile and onboard cache help smooth burst traffic from application launches, patch cycles, and temporary data staging, making ST3400832AS a practical fit for systems that prioritize compatibility, serviceability, and clear failure telemetry over advanced encryption or flash-tier performance.

Why Choose the ST3400832AS?

The ST3400832AS delivers a balanced density-to-performance ratio for 3.5in bays, enabling straightforward scaling in towers, rackmount chassis, and lab enclosures without changing storage architecture. For IT teams standardizing spares, ST3400832AS supports repeatable deployment and predictable behavior across SATA fleets, with CMR write characteristics that reduce operational variance in backup targets and bulk storage roles.

Seagate designs the Barracuda family with an engineering focus on long-term mechanical stability, broad controller interoperability, and manufacturing controls aligned with modern data center expectations for traceability, environmental compliance, and lifecycle continuity.

Key Applications:

• OS and application drive for workstations
• Local scratch and staging storage
• SMB and legacy server SATA bulk storage
• Backup target volumes
• Lab spares and replacement media for 3.5in SATA bays
