Internal Hard Drive SEAGATE Barracuda ST8000DM004 — 8 TB 5400 RPM 256 MB SATA III 3.5"

SEAGATE Barracuda ST8000DM004 is an internal 3.5-inch hard drive with 8 TB capacity, 5400 RPM spindle speed and 256 MB cache. It connects via Serial ATA III (SATA 6 Gb/s) and is designed for desktop storage, backups and mass data archiving. The drive is suitable for single-drive desktop systems, external enclosures or RAID arrays where high capacity and energy-efficient operation are required.

Advantages

The drive offers a large 8 TB capacity combined with a 256 MB buffer for improved data throughput and Multi-Tier Caching Technology for better read/write responsiveness. Its 5400 RPM spindle speed provides a balance between lower power consumption and quiet operation, making it appropriate for energy-conscious desktop setups. The 3.5-inch form factor is standard for desktops and many external enclosures, simplifying upgrades and replacements.

Suitable for

• Desktop PCs requiring high-capacity storage for files, media and backups
• External desktop enclosures and personal NAS units
• Single-drive systems or RAID arrays where high capacity and low power draw are priorities

When it may not be suitable

This 5400 RPM drive is not optimized for applications that require sustained high IOPS or the lowest possible latency, such as high-frequency database servers or intensive virtualization hosts. If your workload depends on maximum random-write performance or very low latency, a higher-RPM HDD or an SSD would be more appropriate.

Key specifications

• Capacity: 8 TB
• Form factor: 3.5 inch
• Interface: Serial ATA III (SATA 6 Gb/s)
• Spindle speed: 5400 RPM
• Cache/buffer: 256 MB
• Typical use: Desktop storage, backups, archival
• Weight: 0.63 kg

How to use

Install the drive into a compatible 3.5-inch drive bay in your desktop, NAS or external enclosure and connect it to a SATA III port and power connector. Initialize and format the drive in your operating system to create partitions and file systems suitable for your use (for example NTFS for Windows or ext4 for Linux). For RAID configurations, follow your motherboard or controller manufacturer’s instructions to add the drive to an array and verify redundancy and rebuild settings.

What to consider before purchase

• Verify your system supports a 3.5-inch drive bay and SATA III interface
• Assess whether 5400 RPM performance meets your application needs versus higher-RPM drives or SSDs
• Check available physical space and cooling to ensure proper airflow for a 3.5-inch desktop drive

Usage recommendations

Use this 8 TB SEAGATE Barracuda drive for high-capacity desktop storage, regular backups and archival tasks. Pair it with adequate cooling, use it in appropriate single-drive or RAID configurations, and consider an SSD for OS or latency-sensitive applications.
