Seagate Barracuda 4TB 5400 RPM Hard Drive

The Seagate Barracuda ST4000DM004 is a 3.5-inch internal hard drive designed for desktop PCs, all-in-one systems, home servers, and entry-level direct-attached storage devices. With 4 TB of formatted capacity and a multisegmented 256 MB cache, it provides ample room for operating systems, application libraries, large media collections, and project archives — all accessible over a SATA 6 Gb/s interface that supports transfer rates of 6.0, 3.0, and 1.5 Gb/s for broad compatibility with modern and legacy motherboards. Running at 5,400 RPM, the drive balances sequential throughput with reduced acoustic output and lower power draw compared with higher-speed alternatives. The maximum sustained transfer rate from the outer diameter reaches 190 MB/s, which is sufficient for everyday desktop workloads, backup tasks, and local media streaming. Advanced Power modes allow the drive to step down to idle (2.5 W average) or standby/sleep (0.25 W) when not actively in use, helping to lower system energy consumption without impacting responsiveness during active periods. The Barracuda ST4000DM004 uses 4,096-byte sectors (Advanced Format) and is rated for a workload of up to 55 TB per year, making it appropriate for typical personal-computing use. Load/unload cycle endurance is rated at 600,000 cycles, and the non-recoverable read error rate is specified at no more than 1 per 10^15 bits read — a standard reliability metric for desktop-class drives. The drive is halogen-free and RoHS-compliant, reflecting adherence to common environmental standards. Physical dimensions are 146.99 mm (D) × 101.85 mm (W) × 20.20 mm (H) with a weight of 490 g, fitting the standard 3.5-inch drive bay found in most desktop towers and compatible enclosures. Operating temperature range spans 0 °C to 60 °C (drive case, max), with non-operating storage rated from −40 °C to 70 °C.
