Hard Drive HP 4TB SAS 3.5" 872291-002

HP 4TB SAS 3.5" hard drive is an enterprise-class serial attached SCSI (SAS) storage device designed for use in servers and storage arrays. With a 4TB capacity in a 3.5-inch form factor, this drive provides block-level storage suitable for demanding workloads such as databases, virtualization hosts, backup targets and archival systems. The drive is built to fit systems that accept 3.5" SAS drives and is engineered for compatibility and reliability within HP server platforms.

Advantages

This 4TB SAS drive offers high-capacity storage with enterprise-grade interface performance and sustained throughput for sequential and random workloads. It provides durability features and error recovery suitable for 24/7 server environments, and its 3.5" form factor makes it straightforward to deploy in standard server bays and storage chassis. Compatibility with HP platforms reduces integration effort and supports predictable behavior in managed data center environments.

Suitable for

• Database servers requiring large block storage
• Virtualization hosts and hyper-converged nodes
• Backup repositories and nearline archival storage
• RAID arrays in enterprise storage systems

When it may not be suitable

This drive is oriented to enterprise SAS environments and may not be appropriate for desktop or consumer systems that only support SATA or 2.5" form factors. It is not intended for use where very low power consumption or extreme noise constraints are primary requirements. For workloads that require the lowest possible latency and maximum IOPS, solid-state storage may be more suitable.

Key specifications

• Form factor: 3.5 inch
• Interface: Serial Attached SCSI (SAS)
• Raw capacity: 4 TB
• Designed use: Enterprise/server-class block storage
• Compatibility: Fits systems and arrays that support 3.5" SAS drives

How to use

Install the drive into a compatible 3.5" SAS bay in a server or storage enclosure following the server manufacturer's mounting and hot-swap guidelines. Configure the drive within the server BIOS/RAID controller or storage array management interface, and include it in RAID groups or as a standalone volume according to your redundancy and performance requirements. Initialize and format the drive in the operating system using appropriate file system and partitioning tools for your workload.

What to consider before purchase

• Ensure your server or enclosure supports 3.5" SAS drives and the required SAS interface speed.
• Confirm compatibility with your RAID controller or storage array firmware and drivers.
• Plan for cooling and power requirements in dense server configurations.
• Decide on RAID level or redundancy strategy to meet performance and fault-tolerance needs.

Usage recommendations

For reliable operation, deploy the drive in systems with proper airflow and monitoring, use supported firmware and drivers, and include the drive in a tested backup and redundancy strategy appropriate for enterprise workloads.
