Internal Hard Drive HP Enterprise 861683-B21 4 TB 7200 RPM 3.5" SATA

HPE 861683-B21 internal hard drive is a 4 TB, 3.5-inch Serial ATA (SATA) midline HDD designed for bulk storage in HPE ProLiant server environments. It combines higher capacity with 7,200 RPM performance and is validated through HPE’s qualification process for compatibility and reliability. The drive supports standard monitoring features and is intended for use where large-volume data storage is required without compromising predictable performance.

Advantages

The drive offers a balance of capacity and performance with 4 TB storage and 7,200 RPM spindle speed in a 3.5-inch form factor, making it suitable for dense bulk storage. It is firmware-optimized and tested for HPE platforms, includes support for drive health and pre-failure alerts through HPE management tools, and benefits from HPE’s signed firmware and carrier reporting for improved security and monitoring.

Suitable for

• Archival and bulk data storage on HPE ProLiant servers
• Cloud and web infrastructure requiring high-capacity drives
• Backup repositories and nearline storage

When it may not be suitable

This midline SATA drive is not intended for the highest I/O workloads such as heavy transactional databases or latency-sensitive applications where enterprise-class SAS SSDs or NVMe storage would be more appropriate. It is optimized for capacity and predictable throughput rather than maximum random IOPS.

Key specifications

• Capacity: 4 TB (4000 GB)
• Form factor: 3.5-inch (Large Form Factor)
• Interface: Serial ATA (SATA), 6 Gbit/s
• Rotational speed: 7,200 RPM
• Typical weight: 1.36 kg

How to use

Install the 3.5-inch drive into a compatible HPE ProLiant server bay or storage enclosure following HPE installation guidelines. Use the HPE Smart Array controllers and HPE Systems Insight Manager or your preferred monitoring tools to enable drive health reporting and pre-failure alerts. Configure RAID or storage pools as required by your deployment and perform regular backups according to your data protection policy.

What to consider before purchase

• Ensure physical compatibility with 3.5-inch drive bays in your server or enclosure.
• Confirm your server controller supports SATA 6 Gbit/s and the drive’s features.
• Assess whether 4 TB at 7,200 RPM meets performance needs versus SAS or SSD options for high I/O workloads.

Usage recommendations

Use this HPE 4 TB 7200 RPM SATA drive for capacity-focused deployments such as backups, archival storage, and cloud/web infrastructure. Pair with HPE-supported controllers and monitoring tools to maintain predictable performance and enable pre-failure alerts.
