HDD Hewlett Packard Enterprise 4TB 3.5 SAS 12G 7.2K 833928-S21

The Hewlett Packard Enterprise 4TB 3.5" SAS 12G 7.2K hard disk drive provides 4 terabytes of storage capacity in a 3.5-inch form factor, intended for use in enterprise servers and storage arrays. The drive uses a 12Gb/s SAS interface and a 7,200 RPM spindle speed to balance sustained throughput and predictable latency for mixed read/write workloads. Built to operate in multi-drive systems, it targets environments that require consistent performance, high capacity and compatibility with server-class storage controllers.

Advantages

This 4TB SAS drive delivers a combination of high capacity and enterprise-grade connectivity with a 12G SAS interface for faster data transfers compared with earlier interfaces. The 7,200 RPM speed helps maintain steady sequential throughput while supporting moderate random I/O common in virtualization, databases and backup applications. Its 3.5-inch form factor and enterprise design provide compatibility with rack-mounted servers and storage enclosures, and it is engineered for continuous operation in data center conditions.

Suitable for

• Primary and secondary storage in rack and tower servers
• High-capacity storage arrays and JBOD enclosures
• Backup and archival systems requiring large sequential capacity
• Database and virtualization workloads with mixed I/O patterns
• Enterprise applications that need durable, continuously-operable drives

Key specifications

• Capacity: 4 TB
• Form factor: 3.5-inch
• Interface: 12 Gb/s SAS
• Rotational speed: 7,200 RPM
• Optimized for enterprise server and storage array operation

How to use

Install the drive into a compatible server chassis or storage enclosure that supports 3.5-inch SAS drives and 12Gb/s SAS connectivity. Ensure the enclosure or controller firmware and driver stack are up to date before introducing the drive into production. Configure RAID or logical volume settings according to your storage policy and monitor initial rebuild or synchronization processes when the drive is added to an array. Follow your organisation’s procedures for secure data migration, and perform health checks via management tools after installation to confirm the drive is recognized and operating within expected parameters.

Usage recommendations

To maximize reliability, deploy this HDD in environments with appropriate cooling and vibration control, and use it alongside enterprise-class controllers and monitoring tools for SMART and array health. For mixed workloads, consider combining these high-capacity drives with lower-latency flash tiers or SSD caches to improve overall system responsiveness while retaining bulk storage on the 4TB SAS drives.
